Description
The BXC60W Series are isolated 60W DC/DC
converters. Designed with highly efficiency, allow the
operating temperature range of these units to be -40°C
to +85°C in a 50.8×50.8×12.7mm shielded metal case.
Further features include wide 4 : 1 input voltage range,
remote on/off control, short-circuit protection, over
voltage protection and over temperature protection.
Applications
These converters are well suitable for battery operated
equipment, measurement equipment, telecom, wireless
network, Industry control system, everywhere where
isolated, tightly regulated voltages and compact size are
required.
