Description
The REC3A 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 +85°C temperature range without derating.
