H Series 50 Watt DC-DC Converters have rugged electrical and mechanical design, regulated output 1, tracking outputs 2 and 3, operating ambient temperature range -25.71°C with convection cooling
The H Series 50 W DC‑DC converters from Power-One accept a wide input voltage range up to 60 V DC and can deliver 1, 2 or 3 regulated outputs up to 48 V DC. They feature a rugged electrical and mechanical design, with output 1 regulated and outputs 2 and 3 tracking, and achieve efficiencies up to 86 %.
The converters meet extensive safety and environmental standards, including EN 60950, UL 1950, CSA C22.2 approvals, IP40 protection, and overtemperature shutdown with auto‑restart at 100 °C. Options such as extended temperature range, undervoltage monitoring, and various mounting accessories are available.
