The 88W TDK-Lambda brand DRL100‑24-1/C2 has a 24V output and meets the requirements of US NEC (National Electric Code) Class 2 in accordance with UL1310 as well as Class II construction (no ground wire needed). 

The supply 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 500mW 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.
