PB-300P Series - 300W PFC Single Output Battery Charger



Designed for lead-acid batteries featuring 3 stage charging characteristics and the automated derating capability for charging current under high ambient temperatures, these intelligent chargers will quickly and efficiently feed your hungry batteries and ensure the lifetime of them at the same time. With the passive PFC function, PB-300 can comply with the harmonic requirements of EN61000-3-2 & equipped with an IEC320 C14 AC Inlet and ON/OFF switch this unit is very convenient for both household and general consumer use. The 48.5mm low profile design also solves a lot of installation troubles and space issues.
