The New LDP pulsed laser diode drivers are the second generation of precision pulsed diode drivers offered by Lumina Power. Building on more than a decade of experience in laser diode driver technol-ogy the new LDP drivers are capable of outputting up to 300 amps . Pulse widths of 30µs. through CW operation are now possible at rep-rates to 10kHz. The LDP incorporates new technology that en-hances pulsed performance while reducing circuit complexity shrinking the size of the package and increases reliability.

Offered in 2 packages, the “S” version for high cur-rent pulse widths to 3ms. and the “L” version for high current pulse widths to 30ms*. The new LDP series pulsed laser diode drivers give the laser designer maximum versatility in a low cost compact package.

Note: 100 to 240VAC ±10% input can be used if average power does not exceed 1000 watts. Average power levels above 1000watts require an input of 200 to 240VAC ±10%. Power supply will shut down if power exceeds 1kW while operating from an input below 200 to 240VAC ±10%





Pin # Pin Name Functional Voltage Level Description

1Enable

(input)

High = RUN = +5 to +15V

Low = OFF = 0V

Default/NC = OFF

The Enable function turns the output section of the power supply ON and OFF. When the power supply is enabled, current is delivered to load as programmed via Iprogram(+), Pin 7. Rise times resulting from Enable are approximately 25msec.

Enable signal must be asserted or toggled after AC power has been applied because the power supply starts up in disabled state disregarding the status of the Enable signal. 10kΩ input impedance.

2 Fault Fault = LOWFault occurs when max energy exceeded, load voltage is too high, no load or over temp. Toggle pin 1 to clear if fault has been removed.

3Interlock

(input)

Open = OFF

Connect to GND = RUN

The Interlock function can be connected to external interlock switches such as door or overtemp switches. Less than 0.3V = ground

4, 9 GND Interface RTN

5 Vout Monitor: (output) 0 – 10V = 0 – Voutmax

Monitor real time output voltage.

1k output impedance

6 Iout Monitor: (output) 0 – 10V = 0 – Ioutmax

Monitor real time output current.

1k output impedance

7Iprogram(+):

(input) 0 – 10V = 0 – Ioutmax

The power supply output current is set by applying a 0-10V analog signal to Iprogram(+).

50k input impedance

8Pulse Control

(input)

TTL/CMOS High = On

TTL/CMOS Low = OFF

Default/NC = OFF

The output is OFF by applying a TTL 0 to Pulse Control, pin 8. When a TTL 1 is applied to pin 8, the amplitude of the output current pulse is determined by the current level programmed via Pin 7, Iprogram(+). There will be a fixed propagation delay of output current vs. Pulse.

ModelsThe “S” Version

The LDP-2000-XX-YY-S is the “short pulse” version of the series and can output up to 300A over a pulse width range of 30µs to ≈3ms. derating to 100A through CW. The LDP series is capable of repetition rates to 10kHz and can be operated from 100 to 240VAC for a maximum of 1000W average and 2000W average when operating from 200 to 240VAC .

The LDP-2000-XX-YY-L is the “long pulse” version of the series and can output up to 300A over a pulse width range of 30µs to ≈30ms. derating to 100A through CW.

Performance Level “E” Safety Standard

The new LDP series Laser Diode Drivers can be specified to include the optional Safety Relay board and interface that allows the laser designer the ability to monitor the power supplies per-formance and signal the user if a fault occurs. This feature by redundant, forcibly guided relay contacts, is made to comply with external machine peripherals up to the highest safety standards of IEC/EN 13849-1 or IEC/EN 62061 and can be used to replace manually operated safety shut-ters in some applications. When ordering or inquiring about this feature please refer to the “SR” option.
