CMDBW
The CMDBW series of high efficiency chassis mount DC/DC converters are single output modules with up to 40 watts of output power. This product is ideal for telecom and networking applications, and is designed for a 4:1 input range of 9VDC-36VDC or 18VDC-75VDC. Some features include 1600VDC isolation, remote on/off, and output adjustability. All models are short circuit, over load, and over voltage protected. Chassis mounts come in open frame, U channel, and enclosed types.
