1U – 19″ Rack Mount Inverter 3.5 kVA/3kW

RM-PSW3K5VA Series – 24V & 48VDC Input Voltage Options

The RM-PSW3k5VA Series are 1U Rack Mount 3.5kVA sine-wave inverters. 24/48VDC models with 230 or 120VAC output. The Bypass / Transfer function, allows for automatic transfer of the load ( in the event of inverter or DC Failure ) from the inverter to the utility AC supply, thus providing a high level of system reliability.

A range of protection features such as ‘Auto shutdown’ that prevents total battery discharge and the extremely low input current draw when output is not powering equipment ensures maximum battery capacity at all times. The voltage is user selectable: 220/230/240V RMS  3%, allowing for the best setting for customer equipment. In normal operation these inverters isolate the load from wide voltage swings, transients and noise usually present in the mains and which can cause equipment reliability problems. Output voltage and frequency are programmable from the front panel, as well as from the RS232 communications interface which can be used for remote monitoring.
