Battery charger generates 500W
Constant voltage switch mode battery charger with automatic temperature compensation for industrial and other harsh environments uses advanced high frequency conversion topology.
Absopulse Electronics' BCH501-BTC is a constant voltage switch mode battery charger with automatic temperature compensation for use in industrial and other harsh environments It uses advanced high frequency conversion topology to generate 500W from a jumper selectable 110/220V AC (+/-15%) input and provides standard output float DC voltages of 13.8V/36A, 27.6V/18A or 55.2V/9A for 12, 24 or 48V DC batteries respectively

Convertor provides high power gate drive
The HIS120 is a high voltage isolated DC/DC convertor developed for high power gate drivers and similar applications in oil and gas, mining, railway track-side and industrial environments.
Other output voltages are available on request.
The battery temperature compensation function ensures optimum charging at various temperatures.
The temperature sensor signals the charger to fine tune its output voltage: as the battery temperature rises, the charge voltage is automatically reduced, when the batteries cool, the charge voltage increases.
The adjustment rate (slope) is about 3mV/cell/C for lead acid batteries.
BCH501-BTC is ruggedised, has a low battery disconnect function, a built-in charger fail alarm and a low battery alarm, both Form C.
It is natural convection and conduction cooled and is rated for operation over a -40 to +50C temperature range.
The unit also has inrush current limiting, overvoltage protection, rectangular current limiting with short circuit protection, self-resetting thermostat for thermal protection and battery reverse polarity protection.
This battery charger is housed in a 15.2 x 6.7 x 35.1cm chassis and weighs 2.6kg.
