The PB256 Series is a range of 13.8Vdc and 27.6Vdc off-line battery chargers / DC uninterruptible power supply that run on 220/240Vac mains electricity. These devices, when linked to a lead-acid battery, offer continuous power to a DC load in the case of a power outage.
A two-step current restricted float charger, battery charge current limiting, a battery low voltage disconnect, and mains/charger and battery alarms are all included in the PB256 Series. It uses high-efficiency technology and produces very low output noise, making it suited for powering a wide range of loads like security, radio, scada, control equipment, and alarm systems, among others.
The PB256 comes with a chassis mount enclosure that fits into the WMBB wall mount box. To run at maximum power, 140W models require a supplemental heat sink. Natural convection cooling is used in all models.
