TDK Corporation is introducing the DRL series of 10 to 100W DIN rail mount AC-DC power supplies with efficiencies of up to 90 per cent. Featuring a low profile and very narrow width, the units are well suited for wall-mounted enclosures commonly used in building automation and security applications. With an average efficiency of up to 87 per cent, 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 55.6mm and 91mm, respectively, and widths of 18, 36, 54 and 72mm for the 10W, 30W, 60W and 100W-rated models. The supplies operate from a wide range input of 85–264V AC and can withstand a 300V AC peak for 5 seconds. All package sizes have a 24V output and 12V is available for the 10, 30 and 60W models. The 30, 60 and 100W outputs are adjustable either from 12–15V or 24–28V.
The DRL has a Class II (double insulated) construction, requiring no earth ground connection, and 3000V AC input to output isolation. Off-load power consumption is less than 0.3W for the 10 and 30W and less than 0.5W for the 60 and 100W versions. All models are convection cooled and are rated for operation in -20 to +71degC 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.
