The TDK-Lambda DRF series of DIN rail power supplies has been designed for medium power applications that require advanced control features including industrial equipment, building automation and process control, operating from a universal input of 85 to 265 Vac (47-63Hz) with active power factor correction to ensure EN61000-3-2 compliance. They have average active efficiency of over 87% and low standby power consumption (below 0.5W to 0.75W depending on the model).

Three 24Vdc output models – DRF120-24-1 (5A), DRF240-24-1 (10A) and DRF480-24-1 (20A) – have 150% peak power capability for 4 seconds and steady constant current characteristic, for loads found in automation applications. Achieving up to 94% efficiency, the DRF operates over -25 to +70°C, with full load operation between -25 and +60°C, derating to 75% load at up to +70°C. Control features include over voltage, over current and over temperature protection and remote on/off. The models also have series and parallel operation capability.

DRF120-24-1 measuring 36.5 x 123.4 x 115.4 mm, saving space on the DIN rail. The DRF240 and DRF480 are 49mm and 82mm wide respectively. All DRF models will mount on either a TS35/7.5 or TS35/15 DIN rail and have been rigorously tested for shock and vibration while mounted. The units are approved to UL508 safety standard for industrial control equipment and hold up, meeting SEMI F47 requirements at high line input (200V only). Further safety approvals include IEC/EN 60950-1 (2nd Ed.) and UL/CSA 60950-1. CE marked in accordance with the LV Directive, EMC Directive and RoHS Directive, the DIN rail power supplies meet EN55022 and CISPR22 Class B for conducted and radiated EMI.
