Three-phase UPS DELPHYS MX

from 250 to 900 kVA

• Parallel system with modular units.• Powerful central bypass for power extension

or redundancy.• Tier 3 and Tier 4 compatible.• Designed for optimal use with STS in

downstream network.

Easy to Service and Maintain

• Specially designed graphic touch screen for easy and ergonomic operation.

• 7 com-slots plug-in communication interfaces for upgrading your operating requirements.

• easy remote monitoring via web browser or via customer’s supervision systems (web, intranet, extranet…).

• Very open connectivity (Modbus / Jbus, Jbus tunnelling, LAN…).

• front accessibility for all components.• Reduced MTTR thanks to extractible power

bridges or fans on “cassette”.

User-friendly operation and remote communication

Flexible architecture

• Internal fault tolerant architecture with internal redundancies and fan failure localisation.

• Intelligent embedded battery monitoring with failed block localisation and preventative remote alarm.

• Able to withstand an output short circuit and overload, ensuring the systems safety under extreme conditions.

• Reliable and robust paralleling mode.• Multisystem automatic cross synchronisation

(ACS) for an optimised use with STS.• Output isolation transformer to reduce

the influence of N-GND (Neutral Line-to-Ground) voltage and load harmonic current on UPS inverter.

• Minimised running costs, by: - Very high efficiency of up to 93.5 %

(lower energy dissipation and cooling costs) equals energy saving in full on line conversion,

- ‘energy saver’ on-line mode allows the number of running units of the system to adapt automatically to the real load,

- free cooling compatible to save cooling costs.

• Valuable space saving with its reduced footprint and exceptional high power density (the most compact unit of its class): 900 kVA in less than 3.2 meters (width) per unit including the by-pass. DELPHYS MX units can also be installed without side or rear access (dependant on requirements).

• Lower infrastructure installation costs benefit from PfC “clean input” rectifier (without filters) with a lasting high input power factor whatever the operation conditions. It means lower input current, in comparison with traditional UPS, therefore no need to oversize upstream transformers or generator sets.

• Intelligent built-in battery monitoring system interacts with “charging mode” to prolong battery lifetime (reduced battery stress thanks to a very low ripple current). The independent charger permanently isolates the batteries from the inverter DC bus in normal mode.

• Designed to match latest IT load requirement.

• Leading power factor load compatible without derating.

Fault tolerant architecture

DELPHYS MX integrates internal redundancy that ensures permanent power supply even during system failure:• redundant ventilation system,• ring bus synchronisation,• no single point of failure since the

synchronisation bus uses a fault tolerant token ring topology that accepts an accidental opening of the synchronisation loop, without UPS malfunctioning or load losses and an alarm is given to the operator at the first fault.

• “Cascade failure” protection function eliminates fault propagation downstream of a module in parallel system when configured with central bypass,

• internal or external “backfeed” protection eliminates any risk of energy feedback upstream of the UPS,

• hardware and software watchdog ensures that the power supplied to applications is secure in case of a circuit and control software fault,

• redundancy of the power supplied to the electronics, locating ventilation faults, preventative detection of faults on a battery component on request.

Protecting your battery investment

EBS (expert Battery System) technology significantly prolongs the battery life:• charge according to an algorithm which

adapts to the environment and the condition of the battery,

• eliminates overloading effects due to permanent floating, which accelerates the corrosion of the positive plates and causes the separators to dry out,

• isolation of the DC battery bus, (independent charger function). Premature ageing, caused by residual ripple from the inverter bridge is eliminated.

Guaranteed battery availability

• the battery and DC circuit are regularly tested automatically and the operator is notified of their condition,

• Available as option, BHC Interactive (Battery Health Check), a battery monitoring system that provides permanent monitoring of the battery system, simplifies maintenance (either preventative or curative) and optimises battery lifetime.

Interacting proactively with the battery charger recharging system (EBS), it optimises battery capacity, increases charger precision, performs automatic battery testing and automatic procedure to recover a block when becoming weaken before it is totally unusable.

DELPHYS MX ensures your power supply is of the utmost quality by using Space Vector Modulation (SVM) digital regulation:• perfectly sinusoidal output voltage THDV <  2 %  with  linear  loads  and  <  3 %  with non-linear loads,

• output voltage precision even when load is completely unbalanced between phases,

• an immediate response to major variations in load, without deviating the output voltage (± 2% in less than 5 ms),

• a very high short circuit capacity up to 4 In (Ph / N) allows selectivity.

Components and power bridges (integrating the latest high performance IGBT) enable the supply:• non-linear loads with high crest factor up

to 3,• loads with a leading power factor up to

0.9 lagging without de-rating of the active power (900 kVA / 800 kW).

DELPHYS MX guarantees total compatibility with your low voltage electrical power supply system and, in particular, with generating sets:• sinusoidal current at rectifier THDI input:

4.5 % without filter,• increased power factor upstream of the

rectifier: 0.93 without filter, reducing the current consumed, and therefore the size of cables and protective devices,

• gradual, sequential start-up of the rectifiers in parallel, facilitating take up by the generating set,

• delayed battery recharge when running on generating set to reduce power consumption.
