Cosel Co., Ltd. R150U-12 AC-DC Power Supply Module

The COSEL R150U-12 AC-DC power supply module provides a reliable, compact source of 12 VDC power for industrial control systems. It accepts 85–132 VAC (1 phase) or 110–170 VDC input with an input frequency range of 47–440 Hz and delivers 12 VDC at up to 13 A (156 W), with an adjustable output from 10.8 to 13.2 VDC to suit load conditions. The unit is panel-mount, measures 44.5 × 93 × 175 mm, and relies on natural convection cooling, while including protection features such as inrush current limiting, overcurrent protection, and overvoltage protection. Certified for UL60950-1, CSA C22.2 No. 60950-1, and EN60950-1, it’s well-suited for industrial automation, control cabinets, telecommunications equipment, and process lines that require a stable 12 V supply for PLCs, relays, sensors, and field devices. Common replacements in COSEL's R150U family include the R150U-12, R150U-12-N, and PBA150F-12-N.
