Parallel Processing UPS E33A ( 100 - 300 kVA / 90 - 270 kW)


A UPS that featires high efficiency, high quality, high reliability operation.It suplies high quality power to devices such as telecommunications equipment since an inverter connected in parallel absorbs noise and adjust voltage while providing power from commercial power supply at normal times.

Input    : AC 380V, 400V, 415V, 420V (3 phase 3 wires/4wires)
Output : AC 380V, 400V, 415V, 420V (3 phase 3 wires/4wires)

Parallel Operation: 100kVA, 200kVA, 300kVA
Parallel redundant: 100kVA, 200kVA

High Efficiency

  • achieves 98% efficiency, running costs can be drastically reduced
  • contribute on protecting the environment.

High Quality

No interruption of output power
Suplies power in sine wive and completely without interruption of output even when there is a power outage, such as black out instantaneous power break or voltage dip.
when a surge generates by injection of a static capacitor etc, the power feeding is switched temporally mode which supplies power from inverter.
This power supply is not from battery, so stress is not placed on the battery.

Active filter function
A bi-directional inverter makes the UPS input current into a sine wive. it removes harmonic current. At the same time, power factor is improved and becomes approx 1.0.

High reliability

Parallel redundant operation
E33A is the industry's first parallel processing UPS, that can perform parallel redundant operation.
