Back-up DC source with inverter IMCO POWER PSI15.JS, SNMP

The IMCO POWER PSI15 series is an unique solution for power backup. It has 12, 24 or 48 V DC output, but also includes an inverter module that produces pure sine 230 V / 50 Hz. The advantage of this solution compared to conventional UPS is the possibility of connecting common lead / GEL / AGM / LiFePO4 batteries with a large capacity and simultaneous power supply of the device with DC voltage. The power supply also allows direct start from connected batteries without the need of the 230 V.

Thanks to the built-in Ethernet interface it is possible to monitor the power status via the web interface or SNMP or perform a remote battery capacity test. The UPS supports temperature compensation for battery charging and allows you to set 4 different charging currents to ensure long battery life. The programmable inputs / outputs can then be used, for example, to switch ventilation in the rack or as alarm inputs.

The PSI15 designed for mounting in 19" rack / 2U position. The mains connection is via a flexible supply, the inverter output is via a standard socket on the back. The battery and outputs are connected via the terminals on the front.
