DESCRIPTION

APPLICATIONS

• Battery Operated Equipment

• Telecom

The DCBUB12 series of isolated DC/DC power converters provides up to 12 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 4:1 input voltage ranges of 9-36VDC and 18~75VDC.

Some features include high efficiency up to 87%, 1500VDC I/O isolation, remote on/off

control, and -40°C to +85°C operating temperature range. The DCBUB12 series is RoHS

compliant and has short circuit, over load, and over voltage protection. These converters

are best suited for use in battery operated equipment, measurement equipment, telecom,

wireless networks, industry control systems, and anywhere where isolated, tightly

regulated voltages and compact size are required.
