Batteries are external and a 2U battery rack can also be provided if required. Battery capacity depends on output load power required and length of hold up time in the event of a power failure. Every unit incorporates an intelligent interface which allows the user to
monitor the battery condition, input power condition and load status via an LED-based front panel display. Monitoring is achieved via dry contacts, RS232, USB and the optional SNMP Card.
Models in the PFD Series meet the requirements of EN60950, measure 1U x 19in x 250mm deep and weigh 3.5kg (150W) and 4.5kg (300W). This product is ideal for any application where battery back up is required in the event of an AC power failure.
