960 W DIN Rail Supply Boasts 95% Efficiency

TDK has announced the addition of a 960 W rated model to its 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 24 V output, adjustable from 24 V to 28 V, using either the front panel mounted trim potentiometer or an external 5 to 6V source. The input range is 180 to 264 VAC, withstanding surges of up to 300 VAC for 5 seconds. The operating ambient temperature is -25°C to +70oC, -40°C cold start, derating linearly above 50°C to 75% load at 70°C. The DRF series warranty is five years.

The DRF960-24-1 is 123.4 mm tall, 139 mm deep and has a narrow 110 mm width saving both space on the rail and in the cabinet. Remote on/off and a 30 V 1 A 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 1 W. 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 3,000 VAC, input to ground 1500 VAC and output to ground 500 VAC. 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.

120 W and 240 W DIN Rail Power Supplies Boast 93% Efficiency

TDK has announced the introduction of 120 W and 240 W rated models to the DRB series of AC-DC DIN rail mount power supplies. Their narrow width allows additional devices to be installed on the rail, saving cabinet space. The high 93% efficiency produces less internal waste heat enabling electrolytic capacitors to run cooler, extending field operating life to greater than 7 years at 75% load, 230Vac input. Applications include industrial process control, factory automation, semiconductor fabrication and test and measurement equipment.

Rated for continuous operation at 120 W and 240 W, the DRBs can deliver a +20% peak load for up to 10 seconds. The power supplies are currently available with a 24V output, adjustable from 24 V to 28 V, and can accept an 85 to 264 Vac input withstanding surges of up to 300 Vac for 5 seconds. The operating ambient temperature is -25oC to +70oC, -40oC cold start, derating linearly above 55oC to 50% load at 70oC.

In addition to a front panel LED, an isolated DC OK opto-coupled signal is provided to show the output status either locally or remotely. The DRB120 and DRB240 have a rugged metal enclosure measuring 124 mm in height, 125 mm deep and narrow widths of 35 mm and 41 mm respectively.

Input to output isolation is 3,000 Vac, input to ground 1500 Vac and the output to ground is 500Vac. Both models are certified to the safety standards of IEC/UL/CSA/EN 60950-1, IEC/UL/CSA/EN 62368-1, UL508, IEC/EN 62477-1 (OVC III) and are CE marked in accordance to the Low Voltage, EMC and RoHS Directives. The DRBs are compliant to EN55011-B, EN55032-B, CISPR11-B, CISPR22-B, EN61204-3 (Class A) radiated and conducted emissions, EN 61000-3-2 harmonics, IEC 61000-4 immunity and SEMI F47 line dip standards.
