February 13, 2017 – Bel Power Solutions, a manufacturer of power management devices, announced the release of its MELCHER HP Series DC-DC converter (4TE) with an input voltage range greater than 10:1. The converters deliver up to 192 watts with efficiency up to 93% over input and load range with no derating over the operating ambient temperature range of -40° to 70°C.
One power supply covers 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. 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 and adjustable output voltage. 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.
