Bel Power Solutions, a Bel group company, (NASDAQ: BELFA and BELFB) and premier global manufacturer of power management devices, announces the release of its MELCHERTM HP Series DC-DC converter (4TE) with an input voltage range greater than 10:1. The converters deliver up to 192 watts with typical efficiency up to 93% over input and load range with no derating over the operating ambient temperature range of -40° to 70°C.
Just one power supply covers all nominal battery voltages from 24 V to 110 V, making it particular suitable for railway applications. The continuous input voltage range is 16.8 V –137.5 V with dynamic transient deviations to 12.5 V and 154 V for 2 seconds respectively. The HP Series complies with EN 50155, EN 50121, fire and smoke standard EN 45545 and all common national and international railway and safety standards, is packaged in a rugged cassette case for 19″ rack or chassis mounting, and all the PCB boards are protected by lacquer, which is perfect for harsh, convection cooled environments in the traditional MELCHERTM style. They are also safety-approved to IEC/EN 60950-1 and UL/CSA 60950-1 2nd Edition.
The HP Series output covers 5 V to 96 V in single, dual, triple or quad output configurations. Standard features include current share, 10 ms interruption time, reverse polarity protection, inrush current limitation, over-voltage and user-programmable under-voltage lockout, remote on/off, adjustable output voltage, fully self-protecting and fully featured. A variety of electrical and mechanical accessories are also available, including a universal mounting bracket for DIN Rail and chassis mounting, a mounting plate for wall mounting and a front panel kit for accommodating 2 HP units for a 19″ DIN rack with 6U, 5TE.
