When space and cost are at a premium, the RECOM RACPRO1-S120 DIN-Rail PSU is the solution. Offering 120W output power from -40°C to +60°C ambient in convection-only cooling, the part is just 100mm high, 112mm deep, and 28mm wide, achieving 500W/liter power density and an efficiency of up to 93.3%. As a bonus, up to 144W is available to 45°C, with a further power boost to 150% for five seconds for surge loads. Adjustable output voltages are available at 12V, 24V, or 48VDC, each with an extended return voltage capability of more than 35V at 24V and 63V at 48V, for immunity to back-feed from inductive and motor loads. A DC-OK signal is also provided. Input is universal single-phase AC, or 88 to 370VDC with active inrush limiting.
