CMYF/CMYFW
The CMYF/CMYFW Series of single output chassis mount DC/DC converters offers up to 20 watts of output power. These converters perform over an ultra-wide input voltage range (2:1 and 4:1), providing indefinite short circuit and overvoltage protection. Some features include 1600VDC isolation, positive or negative remote on/off, and output adjustability. These current mode control forward converters are designed for improved transient response and reduced stress on switching components and do not require external input filtering, making it a preferred source over industry alternatives. Chassis mounts come in open frame, U channel, and enclosed types.
