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.
