Low profile DIN rail power supply conforms to Class 2 and Class II standards
TDK Corporation has introduced 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 satisfy the demands of US NEC (National Electric Code) Class 2 in accordance with UL1310. This makes it fit for use in building automation and security systems needing 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 as no ground wire is required.
The device is housed in a robust plastic case, measuring 72mm wide x 55.6mm deep x 91mm high, the same depth and height profile as the 10W to 100W models in the DRL series. All models operate from a broad 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 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.
