The Cosel RMB15A-2-J is an AC/DC power supply converter from the RMB15A series, designed for ITE (Commercial) applications. This open-frame unit provides dual outputs: +5V with a continuous current of 0.8A and +24V with a peak current of 0.65A. It operates with an input voltage range of 85-132 VAC or 110-170 VDC and boasts a typical efficiency of 68% at 100V AC input.
Key electrical specifications include a maximum line regulation of 20mV for the +5V output and 96mV for the +24V output. Load regulation is a maximum of 150mV for both outputs. The device features overcurrent protection that automatically recovers and overvoltage protection for the +5V output via zener diode clamping.
Designed for convection cooling, the RMB15A-2-J has a compact chassis mount form factor with dimensions of 28mm (W) x 80mm (H) x 100mm (D) and weighs a maximum of 250g. Its operating temperature range is -10°C to +60°C. The unit complies with UL60950-1 and C-UL standards, and meets FCC-B and VCCI-B conducted noise regulations.
The input voltage range is 85-132VAC (47-440Hz) or 110-170VDC.
The converter provides +5V at 0.8A and +24V at 0.65A (peak 0.65A).
The operating temperature range is -10°C to +60°C (non-condensing).
The case size is 28mm x 80mm x 100mm and the maximum weight is 250g (without cover).
It is approved to UL60950-1, C-UL, and complies with DEN-AN, FCC-B, and VCCI-B.
Typical efficiency is 68% at AC 100V input and full load.
Overcurrent protection works above 105% of rating with automatic recovery. Overvoltage protection is provided by zener diode clamping on the +5V output.
