Absopulse announces LTH-65R-F3TH DC-DC converters

Nov. 17, 2016 – The LTH-65R-F3TH series of heavy-duty, railway quality DC-DC converters with pure convection cooling from Absopulse Electronics delivers up to 200W output power.

Designed to float charge hold-up batteries for on-train electrical equipment, the units are also suitable for a range of other transportation and industrial applications. The converters operate from a 12Vdc (10.5-16V) input and deliver 12Vdc, 24Vdc, 48Vdc or the corresponding float voltages. Other input values and output voltages up to 125Vdc are available. An optional built-in redundancy diode allows for paralleling and N+1 operation or back-up battery connection. An output fail alarm (Form C) is also available on request. The units are rated for operation over a -25 C to 55 C temperature range for full specification with no derating required; wider temperature ranges are available on request.
