TDK Corporation introduced the DRL series of 10 to 100 W DIN rail mount AC/DC power supplies with efficiencies of up to 90%. Featuring a low profile and very narrow width, the units are ideally suited for wall mounted enclosures commonly used in building automation and security applications. With an average efficiency of up to 87%, the DIN power supplies also meet ErP efficiency standards.
Housed in a robust plastic case, the DRL series has a common depth and height of 55.6 mm and 91 mm respectively, and widths of 18, 36, 54, and 72 mm for the 10 W, 30 W, 60 W and 100 W rated models. The supplies operate from a wide range input of 85 – 264 Vac and can withstand a 300 Vac peak for five seconds. All package sizes have a 24 V output and 12 V is available for the 10, 30 and 60 W models. The 30, 60 and 100 W outputs are adjustable either from 12 – 15 V or 24 – 28 V.
The DRL has a Class II (double insulated) construction, requiring no earth ground connection, and 3,000 Vac input to output isolation. Off-load power consumption is less than 0.3 W for the 10 and 30 W and less than 0.5 W for the 60 and 100W versions. All models are convection cooled and are rated for operation in -20 to +71°C ambient temperatures (derating applies at high temperature).
The units are certified to IEC/EN/UL/CSA 60950-1, UL 508, are CE marked for the Low Voltage, EMC and RoHS2 Directives, with select models complying to NEC Class 2 in accordance with UL1310. All models meet EN55022-B conducted emissions, EN55022-A radiated emissions, EN 61000-3-2 harmonic currents and EN61000-4 immunity standards.
