EH9335 Three Phase Series (10-80KVA)

High Frequency Three Phase(3/3) Online UPS

The EH9335 series of 3/3 Phase Online UPS adopts double-change online design, with input power factor correction (PFC), which makes the input power factor as high as 0.99. It has a high energy density ratio, which greatly reduces its own volume and floor space of the computer room. Using digital control, the system is highly stable, with selfprotection and fault diagnosis capabilities. This series of UPS can better solve power supply problems such as instantaneous voltage drop, damping oscillation, high voltage pulse, surge voltage, harmonic distortion, clutter interference, and frequency fluctuation for users.

• Double conversion high frequency online design.

• Using digital control, the system is more stable.

• With input power factor correction (PFC), the input power factor is 0.99.

• The number of battery cells can be set according to user needs: ±16/17/18/19/20 cells.

• With parallel interface, 4 units can be paralleled, and battery packs can be shared in parallel.

• The charging current can be set, and the three-stage charging management of constant voltage, constant current, and floating charge can be automatically switched.

• With LCD and LED dual display, users can intuitively understand the working status and parameters of the UPS.

• With a maintenance bypass switch, which can be maintained when the power is uninterrupted.

• The output load capacity is strong, which can adapt to the unbalanced three-phase load.

• With RS232 communication interface and SNMP (optional) card.

• With emergency shutdown (EPO) button interface, in an emergency, press the EPO button to emergency shutdown.
