Inverter SJ-2K0-2K3/DT_4kV

Inverter SJ-2K0-2K3/DT is designed to power devices, that require the input voltage 230 V/50 Hz with maximum continuous power output 2000 W. Input voltage range for this inverter is 48/60 V DC or 110 V DC. This device allows to connect the AC device into DC power system. AC output voltage is pure sine wave with low distortion. It is actively controlled, so it is allways corresponding with sinus reference, even in case with non-linear loads.

An optional LCD control display can be added for alarm, state, load, DC and AC voltage indications.

The device is desktop, with frontal forced ventilation. All Connections are located on the front panel.
