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 are available with either 150W or 300W output power and they meet the requirements of EN60950. They measure 1U x 19in x 250mm deep and weigh 3.5kg (150W) and 4.5kg (300W).
