The Cosel PMA100F-48-RN is an off-board AC/DC power supply module designed to convert universal AC line voltage into a stable 48VDC output. Rated for 100.8W of continuous power delivery, this unit supplies up to 2.1A of output current, making it suitable for powering industrial control systems, telecommunications equipment, and medical devices that require isolated DC power rails.
Electrical performance centers on a wide input acceptance range of 85 to 264VAC at 50/60Hz, ensuring compatibility with global power grids. The converter achieves typical efficiencies of 86% at 100VAC and 89% at 200VAC operation. It incorporates 2kV of reinforced isolation voltage between input and output circuits. Cold start inrush current is specified at 15A under 100VAC and 30A under 200VAC conditions, while leakage current remains within 0.05mA maximum at 100VAC per IEC60601-1 standards.
Thermal management supports continuous operation across an ambient temperature range of -10°C to 70°C without derating. The module utilizes a standard DIN rail or panel mount form factor typical of the PMA series, facilitating straightforward integration into enclosures and control panels. Design engineers should account for the specified inrush characteristics when sizing upstream circuit breakers or fuses to prevent nuisance tripping during initial power-up.
