Latest DRB AC-DC DIN Power Supplies Feature an isolated DC OK Opto-Coupled Signal
Press Release Summary:
The TDK’s DRB AC-DC DIN Power Supplies now include 120W and 240W models with adjustable output rating 24V to 28V. The units accept 85 to 264 Vac input and are able to withstand surges of up to 300 Vac for 5 sec. The devices can be operated in -25°C to +70°C temperature range and are offered with isolation of 3,000 Vac (Input to output), 1500 Vac (input to ground) and 500 Vac (output to ground). They are suitable for applications such as industrial process control, factory automation and semiconductor fabrication.
Original Press Release:
93% Efficient 120W and 240W DIN Rail Power Supplies Have Narrow Width and Long Field Life
TDK Corporation (TSE 6762) announces the introduction of 120W and 240W 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 & measurement equipment.
Rated for continuous operation at 120W and 240W, 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 24V to 28V, and can accept an 85 to 264Vac input withstanding surges of up to 300Vac for 5 seconds. The operating ambient temperature is -25°C to +70oC, -40°C 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 124mm in height, 125mm deep and narrow widths of 35mm and 41mm respectively.
Input to output isolation is 3,000Vac, input to ground 1500Vac 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.
