Inverter SJ-1K0-2K3 with built-in bypass

Inverter SJ-1K0-2K3 with built-in bypass is designed to power devices that require the input voltage 230V/50Hz with maximum power 1000VA. The input voltage range for this invertor is 48/60VDC. This device allows to connect the AC device into DC power system. AC output voltage is purely sinusoidal with low distortion. It's actively controlled, so the voltage course is always adequate to reference sinusoidal even in case of non-linear loads. Versions with integrated bypass allows you to connect AC power supply to its output, and thus implement a backup supply in case of power failure. It is possible to set the preferred power source (INVERTER Mode / MAINS) and thereby determine which input is connected to the output if both inputs are ready. Bypass switch-time is less than 15ms, which does not cause power supply failure in the connected device. The inverter automatically synchronizes the output phase, in accordance to the input "MAINS" phase.

Device includes a status display that indicates its status, alarms and displays, the DC load input and output AC voltage.

The device is intended for mounting into 19" rack, height is 2U and it has a forced ventillation with a front suction and regulation. All Connections are located on the front panel.
