Powersolve has announced the PQE Series of AC-DC battery-backed power supplies designed specifically for applications where constant power is key. Typical installations will include security systems. The PQE Series accepts a universal AC input and provides 1 – 3 DC outputs with battery charger. They can be used with 12V and 24V battery systems.
Output voltages are 13.8V or 27.6VDC and models are also available with an auxiliary +5V 3A output. Output power ratings are 75, 100 or 155 Watts.
PQE Series power supplies incorporate a number of features designed to ensure that constant power is available in the event of mains failure. These include “auto switch” when power off, battery low protection, battery polarity protection, brown-out (AC input low) protection and an integral constant current limiting circuit.
Other significant features include alarm signals for AC OK and battery low, as well as short circuit, overload and overvoltage protection. The PQE Series meet all relevant safety and EMI/EMS standards.
Operating temperature range is up to +70°C with derating and cooling is by integral fan or by an optional external fan mounted on top of the enclosure.
