DESCRIPTION
The DCMUA15 series of isolated DC/DC power converters provides 15 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 DCMUA15 series is RoHS compliant and has short circuit, over load, and over 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.
