Absopulse has introduced the LTH-65R-F3TH series of heavy-duty, railway quality DC-DC converters with pure convection cooling deliver 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 parallelling and N+1 operation or back-up battery connection. An output fail alarm (Form C) is also available on request.
Cooling is via heat-sink fins on the top of the unit, which makes the design ideal for installations where surface mounting is not possible. 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.
The LTH-65R-F3TH converters meet the requirements of EN50155 for electronic equipment used on railway rolling stock, as well as EN50121-3-2 (EMI), EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-6 and EN45545. Protection features include 3000VDC input-output isolation, reverse polarity protection, overload protection, rectangular current limiting with short-circuit protection and thermal shutdown in case of insufficient cooling.
