DPS — industrial IGBT UPS
Country: France · Model: DPS
The industrial DPS UPS on IGBT transistors belongs to class VFI-SS-111 under IEC/EN 62040 and is designed for harsh operating conditions. Its main distinction is high tolerance to short-circuit currents, so a faulty line can be selectively disconnected by a breaker without stopping the whole UPS.

Description
The rectifier and inverter have separate control loops on a dual DSP and PLD programmable logic. The charger works in 5 automatic modes and supports manual control for vented serviced batteries and temperature compensation of the charge voltage. Manual mode is needed for equalizing charge, when staff service the battery in a separate room. The fans are redundant and their flow is monitored, so the failure of one of them does not lead to overheating and shutdown. For integration into process control systems there is Modbus over RS232 or RS485 and an Ethernet port. Protection selectivity means that a short circuit in one outgoing line does not de-energize the other consumers.
How to choose
The power and battery voltage for DPS are agreed per project, so the request should state the load, the battery type and the short-circuit current needed for selectivity. Vented batteries require the manual charge mode, while sealed ones work in the automatic modes. For ordinary server rooms with no selectivity requirements, the modular HELIOS-TH of 10–100 kVA or IRIS+TT of 10–30 kVA will be simpler.

FAQ
Why is short-circuit tolerance important for an industrial UPS?
The DPS UPS delivers a short-circuit current sufficient to trip the branch breaker, so only the faulty line is disconnected.
What battery charging modes does the DPS UPS have?
There are 5 automatic modes, a manual mode for vented batteries and temperature compensation of the charge voltage.
What communication protocols does DPS support?
Modbus over RS232 or RS485, and also Ethernet for connection to SCADA.
How is cooling of the DPS UPS arranged?
The fans are redundant and fitted with airflow monitoring, so the failure of one does not stop the UPS.
Which class under IEC/EN 62040 does DPS belong to?
It is an online UPS of class VFI-SS-111, whose output does not depend on mains voltage and frequency.
