The PB256 Series is a family of 13.8Vdc and 27.6Vdc, 110W / 140W off-line battery chargers / DC uninterruptible power supplies which operate from 220/240Vac mains power. When connected to a lead-acid battery. These units provide uninterrupted power to a DC load in the event of mains failure.
The PB256 Series contains a two-step current limited float charger, battery charge current limiting, a battery low voltage disconnect, and mains/charger and battery alarms. It employs high-efficiency technology, combined with very low output noise that makes it suitable for powering a broad range of loads such as security, radio, scada, control equipment, alarm systems, etc.
The PB256 is available in a chassis mount enclosure and can be fitted into the WMBB wall mount box. A supplementary heat sink is needed for 140W models to operate at maximum power. All models employ natural convection cooling.
