Operating from a universal AC input, the PQE75-155 series units from Powersolve provide 1-3DC outputs with battery charger suitable for 12 or 24V battery systems. Powersolve’s PQE75-155 Series of AC-DC battery backed power supplies are designed specifically for applications like security systems where constant power is a prerequisite.
Output voltages are 13.8V or 27.6V DC and models are also available with an auxiliary +5V 3A output. Output power ratings are 75, 100 or 155W.
The PQE75-155 Series power supplies from Powersolve 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 PQE75-155 Series meet all relevant safety and EMI/EMS standards.
Operating temperature range is up to 70⁰C with derating and cooling for most models is by free air convection while the 155W models are fan cooled.
