CMMDW
The CMMDW series of chassis mount DC/DC converters are single output modules with up to 20 watts of output power. This product is ideal for telecommunications, industrial, mobile, and test equipment applications. These converters are designed for a 4:1 input voltage range of 9VDC-36VDC, or 18VDC-75VDC. Some features include 1600VDC isolation, positive or negative 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.
