A FEATURES ● CE Mark ● 100% Burn In ● Isolated and Regulated ● Wide Input Voltage Ranges ● Fixed Operating Switching Frequency ● Short Circuit and Over Voltage Protected ● Input and Output Filtering Integral to Supply ● UL1950, cUL950, TUV EN60950 File E155800 ● 50, 66, 75, and 100 Watt Output Rating from Same Package DESCRIPTION The CMSP & CMSPW series consists of single output half brick DC/DC converters on a chassis mount that offer up to 100 watts of output power in an industry standard package and footprint. It is intended to provide power and isolation for pc board and chassis mount applications requiring high power density. Some features include wide input voltage ranges, positive or negative remote on/off, remote sense, output trim, short circuit protection, and over voltage protection. Being encapsulated, these supplies have improved thermal dissipation and protection for ruggedized environments. All models are 100% burned-in.
