TDK-Lambda announces the introduction of two additional DRB DIN rail mount AC-DC power supplies, rated at 120 W and 240 W (144 W/288 W peak for 10 seconds). The products have a very narrow width, providing additional space for other DIN rail mount modules. Having efficiencies of 93%, less internal heat is generated resulting in cooler electrolytic capacitors a field life of greater than 7 years at 75% load, 230 Vac input. These models complete the cost-effective 15 W to 480 W DRB series, making it suitable for a wide range of industrial applications including factory automation, process control and test and measurement.
The DRB120 and DRB240 models are housed in a robust metal enclosure, measuring 124mm in height, 125mm deep and widths of 35mm and 41mm respectively. The power supplies can operate from a wide range 85 – 264 Vac input and withstand a surge of 300 Vac for 5 seconds. Both have a 24 V output and feature an isolated DC OK optocoupler signal in addition to an LED indicator. The outputs can be adjusted from 24 – 28 V to compensate for series blocking diodes or FETs in redundant configurations.
Input to output isolation is 3000 Vac, input to ground 1500 Vac and the output to ground is 500 Vac. The DRBs are convection cooled and rated for operation in -25 to +70°C ambient temperatures (cold start at -40°C), derating linearly above 55°C to 50% load at 70°C.
The units are safety certified to IEC/EN/UL/CSA 60950-1, IEC/EN/UL 62368-1, UL 508, IEC/EN 62477-1 (OVC III), and are CE marked for the Low Voltage, EMC and RoHS2 Directives. Both meet EN55011-B, EN55032-B, CISPR11-B, CISPR22-B, EN61204-3 (Class A) radiated and conducted emissions, and comply with the EN61000-4 immunity standards.
