The Cosel RMB50A-2-GN is an enclosed AC/DC power supply designed for ITE (Commercial) applications. It features dual outputs, providing +5V at up to 0.8A and +24V at up to 0.5A (peak 0.65A).
This power supply operates with an efficiency of 74% and is designed for chassis mounting. The input voltage range is AC85 - 132V or DC110 - 170V, with an input frequency range of 47 - 440Hz or DC. It has an operating temperature range of -10°C to +60°C and meets UL60950-1 and C-UL standards.
Key specifications include a start-up time of 100ms maximum and a hold-up time of 10-20ms typical. Isolation is rated at AC2,000V between input-output and input-FG/Cover, and AC500V between output-FG/Cover. The unit measures 155.0mm x 31.0mm x 93.0mm and weighs a maximum of 250g.
The input can be 85-132 VAC (47-440 Hz) or 110-170 VDC.
Output V1: +5V, 0-0.8A. Output V2: +24V, 0-0.5A (peak 0.65A).
The operating temperature range is -10 to +60°C.
Dimensions are 28mm x 80mm x 100mm. Weight is 250 g maximum without cover.
Overcurrent protection activates above 105% of rated current and recovers automatically. Overvoltage protection is provided by a zener diode clamp on the +5V output.
It is approved to UL60950-1, C-UL, and complies with Conducted Noise limits for FCC-B and VCCI-B.
Typical efficiency is 68% at 100 VAC input and full load.
