DESCRIPTION
The DCMUA series of isolated DC/DC power converters provides 5 Watts of continuous output power in a 2.0” x 1.0” x
0.4” shielded metal case. This series consists of single and dual output models with 2:1 input voltage ranges of 9-18VDC,
18~36VDC, and 36~75VDC. Some features include high efficiency up to 87%, 1500VDC I/O isolation, and -55°C to
+95°C extended operating temperature range. The DCMUA series is RoHS compliant and has short circuit, over load, over
voltage, and reverse voltage protection. These converters are best suited for use in military applications, battery operated
equipment, measurement equipment, telecom, wireless networks, industry control systems, and anywhere where isolated,
tightly regulated voltages and compact size are required.
