TDK Corporation Announces 95% Efficient 960W DIN Rail Power Supply With a 1440W Peak Power Capability

February 20, 2019 by TDK-Lambda Corporation

TDK Corporation (TSE 6762) announces the introduction of a 960W rated model to the DRF series of AC-DC DIN rail mount power supplies.

TDK Corporation (TSE 6762) announces the introduction of a 960W rated model to the DRF series of AC-DC DIN rail mount power supplies.  The high 95% efficiency produces less internal waste heat enabling electrolytic capacitors to run cooler, providing a calculated life of in excess of eleven years with a 75% load at 230Vac input.  The unit can supply a peak load of 1440W (24V 60A) for up to 4 seconds to power capacitive and inductive loads.  Applications include industrial process control, factory automation, and test and measurement equipment.

The power supply has a 24V output, adjustable from 24V to 28V, using either the front panel mounted trim potentiometer or an external 5 to 6V source. The input range is 180 to 264Vac, withstanding surges of up to 300Vac for 5 seconds. The operating ambient temperature is -25oC to +70oC, -40oC cold start, derating linearly above 50oC to 75% load at 70oC. The DRF series warranty is five years.

The DRF960-24-1 is 123.4mm tall, 139mm deep and has a narrow 110mm width saving both space on the rail and in the cabinet.  Remote on/off and a 30V 1A rated DC OK relay contact are provided as standard.  When in standby mode using the remote on/off function, the power consumption is less than 1W.  Up to five units can be connected in parallel using the droop mode current share, for systems requiring additional power.

Input to output isolation is 3,000Vac, input to ground 1500Vac and output to ground 500Vac. The DRF960 is certified to the safety standards of IEC/UL/CSA/EN 60950-1, UL508 and is CE marked in accordance to the Low Voltage, EMC and RoHS Directives.  The unit is compliant to EN 55032-B (radiated and conducted emissions), EN 61000-3-2 harmonics and IEC 61000-4 immunity standards.
