A series of ac-dc switching supplies developed by ConTech offers a flexible wrinkle to power design thanks to use of a chassis mount case. The CM25 series offers 25 W of fully regulated power. An easily accessible terminal block and output-voltage adjustment potentiometer build in the versatility for the switches’ use in a wide range of applications. Available output voltages are 5, 12, 24, and 48 V dc, with efficiencies up to 83%. Universal input voltage ranges from 88 to 264 V ac. All models integrate short-circuit, overvoltage, and overload protection. The metal-cage chassis mount case is designed for free air-convection cooling. The series is rated for 3000-V ac isolation and is RoHS-compliant.
