The RACPRO1-S240 Series from Recom Power are Isolated AC-DC Power Supplies that step down an AC input voltage of 85-277 V (3-phase) to a DC output voltage of 24 V. They also accept a DC input voltage of 88-370 V. These converters deliver an output power of 240 W and have an efficiency of up to 95%. They are designed specifically for demanding applications in harsh industrial automation fields with an extended return voltage immunity up to 50 V at the output, making them suitable for safe operation against back-feeding loads like decelerating motors and inductors. These converters provide an extended mains input surge immunity of up to 6 kV (AC) and a return voltage immunity of over 35 V at the output, making them suitable for safe operation against back-feeding loads. They have an adjustable output voltage of 24-29 VDC and an output current of 10 A. These converters support a convection-based cooling mechanism and offer a thermal power bonus of up to 288 W at 45°C with a power boost of up to 150%, which allows them to efficiently power highly inductive and capacitive loads.
These AC-DC power supplies have built-in active inrush current limiters to reduce sudden surges in the current for high reliability. They are also provided with 25° push-in connectors for easy tool-less installation or replacement. These RoHS-compliant converters are available in DIN rail-mount packages that measure 125.0 x 39.0 x 139 mm and are ideal for building, industrial automation, datacom/telecom, infrastructure, and energy applications.
