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.

● Output Current up to 5.5A ● Fixed Switching Frequency ● Six-Sided Continuous Shielding ● 20 Watts Maximum Output Power ● 4:1 Ultra Wide Input Voltage Range ● Options: Negative Logic Remote ON/OFF ● Call Factory for More Output Power Options ● Compliant to RoHS EU Directive 2002/95/EC ● CE Mark Meets 2006/95/EC, 93/68/EEC, and 89/336 EEC ● Chassis Mount Options: Open Frame, U Channel, and Enclosed Types Available
