Just one power supply covers all nominal battery voltages from 24V to 110V, making it particular suitable for railway applications. The continuous input voltage range is 16.8V-137.5V with dynamic transient deviations to 12.5V and 154V for 2s 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 19in rack or chassis mounting, and all the PCB boards are protected by lacquer, which is perfect for harsh, convection cooled environments in the traditional MELCHER™ style. They are also safety-approved to IEC/EN 60950-1 and UL/CSA 60950-1 2nd Edition.

The HP Series output covers 5V to 96V in single, dual, triple or quad output configurations. Standard features include current share, 10ms 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 19in DIN rack with 6U, 5TE.
