Inverter

The TECNED OM(SF/D) inverter series is available with input voltages from 24Vdc to 220Vdc nominal and single phase output. The OM(SF/D) inverters are available in capacities from 5 kVA up to 100 kVA depending on DC voltage levels.

OM (SF/D) inverter can be supplied as standard or fault tolerant systems within a single enclosure to meet customer requirements for safety and reliability.

The OM-SF (software free) model is a strictly analog inverter available with natural convection and forced air cooling depending on rating. Standard features include DC-high/low, output out of limits and general alarm, output V/A metering, potential free contacts and input/output fuse monitoring.

The OM-D model includes an additional digital controller with LCD display that shows the systems current state of operation and system values, allows setting of system parameters and includes event and alarm logs.

Option list (OM-SF/D)
  • Extend to 12x PFC (NO/NC) with LED
  • Fan failure alarm
  • Individual fuse failure indicator
  • DC ground fault
  • Over temperature
  • Up to 6 (DIN 96) meters / cabinet
  • RS485 / Modbus communication (OM-D only)
