Fig. 10: Operating principle

3.1 AC Input

Input over current protection

The SWC has a fuse in both AC lines. The fuses are non-replacable.

Power factor correction

The SWC has a near perfect power factor throughout it’s AC Input voltAge rAnge when connected to resistive loading.

AC Input under voltage

The SWC will not operate when the input voltage is < (130VAC to 144VAC).

Line voltage drop-out, sags and surges

The SWC has no energy storage. Therefore, the AC Out-put is not expected to remain within specified limits during an AC line drop-out or disturbance. No damage will occur to the converter during a line disturbance event.

Brownout and brownout recovery

Brownout and Brownout Recovery takes place within the 130Vac to 144Vac Under Voltage protection band.

NOTEBy design, the output voltage level of the SWC can never be more than the input voltage level. The SWC should be operated within the specified operating input voltage range to achieve defined outputs.

Total Harmonic Distortion (THD) - AC supply provided to SWC

With the input AC supply line waveform suffering 12% THD (flat-top), the SWC can operate continuously under this condition.

3.2 DC Input

+24 VDC supply voltage

The SWC requires +24vDC Supply voltAge for the PWM signal, the internal protection relay and to power the internal fan.

The +24vDC Supply voltAge is to be provided at the Auxil-iary DC Input connector, J1.1

If the +24vDC Supply voltAge is turned off while the AC input voltage is still applied, the SWC will turn off.

To ensure a successful restart, the +24vDC Supply voltAge must not be turned on again for a minimum of 2 seconds.

If the AC Input voltAge is turned off, it is also recommended to turn off the ++24vDC Supply voltAge for a minimum of 2 seconds. This de-energizes circuits and ensures a success-ful restart when the AC Input voltAge is turned on again.

3.3 AC Output

Relationship between AC Output voltage and PWM duty cycle

The amplitude of the AC output voltAge is lineraly propor-tional to the duty cycle of the PWM signal and is defined by the following formula:

a) For nominal AC Input voltAge rAnge: 200 VAC to 240 VAC

V_OUTrms = (230 V * PWM_Duty_cycle) ± 5 Vrms

for the following conditionsPWM_Duty_cycle ≤ 76 % 7.8 Ω ≤ Load impedance ≤ 60 Ω

b) For wider AC Input voltAge rAnge: 176 VAC to 269 VAC

V_OUTrms = MIN [230 V * PWM_Duty_cycle OR V_OUT-rms_LIMIT] ± 5 Vrms

whereV_OUTrms_limit = (0.9 * V_INrms) +2.8

for the following conditions0% < PWM_Duty_cycle ≤ 90% ± 2% 7.8 Ω ≤ Load impedance ≤ 12 ΩOutside the range 7.8 Ω to 12 Ω, the value of V_OUTrms_limit will increase with higher load impedance and reduce with lower impedance.

Fig. 13: Relationship between pWM Duty CyCle and AC output voltAge

NOTEConverter saturation is possible when pWM Duty CyCle > 70% and AC Input voltAge < 230 VAC. This condition is managed by the SWC and will not damage the SWC.



NOTEThe above relationship between pWM Duty CyCle and AC output voltAge for load impedances ≤ 60 Ω. Consult Delta for applications with unusual or non-linear loads.

Linearity specification: 2% over the pWM Duty CyCle rAnge 9% to 76%.Waveform: AC Output is a Sinewave when pWM Duty CyCle is > 9%Response time from PWM signal change: < 21 ms.

Standby mode

To put the SWC in Stand-by mode, switch off the +24 vDC Supply voltAge. In Stand-by mode, the AC power consumption is less than 0.2 W.To change back to operation mode, switch on +24 vDC Sup-ply voltAge again.

AC Output overshoot at start-up

Depending on the AC Input voltAge and the pWM Duty CyCle, the AC output voltAge may overshoot the set level when the SWC is turned on. A large change in pWM Duty CyCle may also cause an AC output voltAge overshoot.

Signals AC/AC Sine Wave Converter SWC 4300

4. Signals

4.1 500 Hz PWM control signal

The SWC output level is determined by a Pulse Width Modulated (PWM) control signal. The PWM control signal is driven by an open-collector driver in the host system which pulls the PWM control signal to ≤ 1 V, from the +24vDC SourCe voltAge, and indicates the AC output voltAge of the SWC must be active. The PWM control signal frequency must be 500 Hz ± 10 Hz.

The SWC limits the maximum PWM signal drive current (IPWM) to < 10 mA through an integrated pull-up resistor.

When the open-collector driver of the host system is off, the AC output voltAge of the SWC is 0 V.

Host system Sine wave converter

Fig. 16: PWM drive circuit

For system loads with impedance < 12 Ω, particularly when the load has previously been inactive (cold start), soft-start strategies should be employed using the PWM to prevent the SWC turning off due to output over current protection. This can happen due to a combination of increased cold resistance and/or AC output voltAge overshoot.

For soft-start, turn on the AC Output using a low pWM Duty CyCle and increase it gradually over several seconds. Typical halogen lamp warm-up times are around 1 to 1.5 seconds.

The PWM signal is fail-safe. If a PWM duty cycle of ≥ 90 % (± 2 %) is detected, the SWC will assume the PWM signal has failed due to a short circuit and will shut down the AC Output.

1) If the pWM Duty CyCle exceeds 76%, the AC output voltAge exceeds the maximum rated 175 VAC.

4.2 FAULT signal

The FAULT signal output indicates to the host system whether the SWC has developed an internal fault or not. In the event of a fault, the FAULT signal will be asserted HIGH. The FAULT signal is available at J1.3.

The FAULT signal is an open collector output that must be pulled-up in the host system.

The FAULT signal will be asserted after the following events:

● Over temperature protection activated ● Over current protection activated for AC Output ● Over voltage protection activated for AC Output ● PWM duty cycle protection activated

4.3 ACOK signal

The ACOK signal output indicates to the host system whether the AC Input voltAge is high enough to enable SWC operation or not. If the AC Input voltAge is > (130 VAC to 144VAC), the signal will be asserted LOW (< 0.4 VDC) to indi-cate SWC is enabled for operation.

The ACOK signal is an open collector output that must be pulled-up in the host system.

Leakage current 0.3 µA

4.4 I_MON signal (Current monitor)

The I_MON signal provides the host system with a DC output voltAge proportional to the AC output Current. The I_MON signal is available at pin J1.6. No pull-up resistor is necessary in the host system.

The scaling factor is 0.1 V/Arms, so for example, 1 V is equiv-alent to 10 A. The voltage range of the I_Mon signal is from 0 VDC to 3.3 VDC with an error of ± 8 %.

The maximum value of 3.3 VDC (which is equivalent to 33 A) is only a theoretical value as the maximum rated output cur-rent of the SWC is 25 A.

4.5 V_MON signal (Voltage monitor)

The V_MON signal provides the host system with a DC output voltAge proportional to the AC Input voltAge. The V_MON signal is available at pin J1.7. No pull-up resistor is necessary in the host system.

The scaling factor is 0.01 V / 1 VAC, so for example, 1 V is equivalent to 100 VAC. The voltage range of the v_Mon signal is from 0 VDC to 3.3 VDC with a tolerance of ± 5 %.

The maximum value of 3.3 VDC (which is equivalent to 330 VAC) is only a theoretical value as the maximum AC Input voltAge of the SWC is 240 VAC nominal.

6.2 AC Input under voltage protection

The SWC will be disabled when the AC Input voltAge is < (130 VAC to 144 VAC).

The AC Input under voltage protecion is not latched. The SWC resumes operation once line voltage conditions return within operating limits.

6.3 AC Output over voltage protection (OVP)

The AC Output will be turned off when an AC Output over voltage event happens.

After triggering, OVP is latched. To unlatch OVP, +24vDC Supply voltAge has to be switched off for a minimum of 2 seconds and then on again.

The OVP trip point is nominally 280 VAC ± 10 VAC.

6.4 AC Output over current protection (OCP)

The AC Output will be turned off when an AC Output over current event happens.

After triggering, OCP is latched. To unlatch OCP, +24vDC Supply voltAge has to be switched off for a minimum of 2 seconds and then switched on again.

The OVP trip point is 30 A ± 1.5 A.

6.5 Short circuit protection

The AC Output will be turned off when there is a short cir-cuit (typically around 300 mΩ) between the AC Output lines or between either of the AC Output lines and protective Earth (chassis).

Fast response circuits are included such that the converter is very likely to survive these short circuits without damage. If damage does occur, the converter will fail safely.

Assuming no damage, once the short is cleared, the SWC can be restarted by switching off the +24vDC Supply volt-Age for a minimum of 2 seconds and then switched on again.

6.6 Over temperature protection (OTP)

The AC Output will be turned off when OTP is activated. OTP can be due to failure of the internal fan or excessive ambient temperature.

OTP is not latched. The SWC resumes operation once ther-mal conditions return within operating limits.

6.7 PWM protection

The AC Output will be turned off when the PWM duty cycle is > 90 % ± 2 %.

After triggering, PWM protection is latched. To unlatch the PWM protection, +24vDC Supply voltAge has to be switched off for a minimum of 2 seconds and then switched on again.

10. Disposal

Do not dispose of electrical appliances as unsorted munici-pal waste, use separate collection facilities instead . Contact your local authorities for information regarding the collection systems available. If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being. When replacing old appliances with new ones, the retailer is legally obligated to take back your old appliance for disposal.
