Description

The system is built from modules in a chassis, so capacity is added in blocks without replacing the whole UPS. Up to eight UPS units are connected in parallel. The permissible input voltage is 138–485 V AC, so the UPS stays in mode even under deep sags and grid imbalance, without going to batteries. KLi lithium-ion racks take less space than lead-acid banks of the same capacity, which reduces the floor area for equipment. A module is replaced in 5 minutes, so recovery after a fault does not need a long shutdown.

How to choose

System capacity is set by the number of modules in the chassis, from 40 to 150 kVA on the HPM3300E. For loads up to 1200 kW a parallel system of several UPS units is assembled. If you need less power, look at the YDC3300 at 10–200 kVA (efficiency up to 95.8%, also up to 8 UPS units in parallel) or the UD at 10–80 kVA. For small systems there is the MEMOPOWER-III at 1–10 kVA. There is only one battery type here, lithium-ion racks.
