REC5A

Description

The REC5A series is cost efﬁcient, general purpose isolated DC/DC converter containing a built in Class

A EMC ﬁlter. The converter is designed to run from industry standard 24V or 5V unregulated supplies

and is typically used to provide an isolated, regulated, short circuit protected output. Under Voltage

Lockout is available as an option. These converters are designed for industrial applications, can drive

high capacitive loads and operate over the full -40°C to +68°C temperature range without derating.
