REC3A-0505SW/H2 Recom Power

2:1 input voltage range Features Efficiency up to 81% DC/DC Converter EMI Class A without external components Regulated Continuous short circuit protection No minimum load required Converters REC3A Description 3 Watt The REC3A series is cost efficient, general purpose isolated DC/DC converter containing a built in Class DIP24 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 Package Lockout is available as an option. These converters are designed for industrial applications, can drive high capacitive loads and operate over the full -40C to +85C temperature range without derating.
