Batteries are external and capacity depends on output load power required and length of hold up time in the event of a power failure. The batteries can also be hot-swapped.
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 which can allow computer monitoring even from a mobile phone.
For protection, the unit’s multi-channel outputs use independent fuses. Rapid response short-circuit protection limits the maximum output current which in turn prevents the fuse from blowing. 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).
