1 / 8 page  C ® US E156931 85-264Vac or 110-340Vdc Universal Input Murata Power Solution’s DMS-PS-CM Series of high-efficiency, chassis mount AC/DC power supplies feature low noise (40mV on main, 8mV on auxiliaries), fully-isolated +24, +12V, and +5V outputs, making them perfect for powering today’s complex instrumenta- tion. A high-current main output is isolated from the AC line by 3000Vac. In dual- and triple-output models, the low-current auxiliary outputs are isolated from the main output by 1000Vdc, and from each other by 2000Vdc, effectively providing double isolation from the AC line! This unprecedented isolation elimi- nates ground loop problems in complex, multiple-instrument applications. Full-load efficiencies of up to 80% and output-power ratings of 5, 10 or 16 Watts, combine to ensure minimal ac power con- sumption. For intermittent use or low-power applications, the 5-Watt model’s no-load quiescent consumption with a nominal 120Vac input is a mere 0.6 Watts---that’s nearly seven times less than a standard 4W night light! These low cost, high-efficiency power supplies can significantly reduce long-term electricity costs in low (<5Watts) to medium (<16Watts) power applications. All DMS-PSX-CM power supplies fea- ture universal inputs of 85-264Vac 50/60Hz, built-in line fuses, and on-board ‘Power On’ LED indicators. At full rated load, hold-up time is typically 20ms at 120Vac, and 80ms at 230Vac. All outputs provide indefinite short-circuit protection and, for added reli- ability, the main high-current output also includes overvoltage protection. A rugged, vibration-proof, chassis mount package incorporates large, shock-resistant terminal blocks for all I/O connections. Multiple outputs, low noise, low cost, high efficiency, double isolation, and rugged construction combine to make DMS-PSX- CM Series AC/DC power supplies the ideal choice for powering today’s sensitive instrumentation, and any electronic device that requires a reliable dc voltage!
