Low profile 88W DIN rail power supply conforms to Class 2 and Class II standards

Posted : 04 Feb 2019

TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand DRL100‑24-1/C2 DIN rail power supply. The C2 model, with a 24V output and delivering 88W of output power, is approved to meet the requirements of US NEC (National Electric Code) Class 2 in accordance with UL1310. This makes it suitable for use in building automation and security systems requiring restrictions on the amount of available output current to avoid wiring damage, even under fault conditions. The C2 model also benefits from a Class II construction (no ground wire needed). 
 
The DRL100-24-1/C2 is housed in a robust plastic case, measuring 72mm wide, 55.6mm deep and 91mm high, the same depth and height profile as the 10 to 100W models in the DRL series. All DRL models will operate from a wide range input of 85 – 264Vac and can withstand a 300Vac peak for five seconds. Off-load power consumption is less than 0.5W and the efficiency is 90% at full load with a 230Vac input.
 
The DRL series has a Class II (double insulated) construction, requiring no earth ground connection, and 3,000Vac input to output isolation. All models are convection cooled and are rated for operation in -20 to +71°C ambient temperatures (derating applies at high temperature).
 
The DRL series is certified to IEC/EN/UL/CSA 60950-1 and UL 508, and is CE marked for the Low Voltage, EMC and RoHS2 Directives. All models meet EN55032-B conducted emissions, EN55032-A radiated emissions, EN 61000-3-2 harmonic currents and EN61000-4 immunity standards.
