TDK Corporation introduces the TDK-Lambda brand DRL series AC-DC DIN rail mount power supplies. With efficiencies of up to 90%, waste heat has been reduced, allowing the use of very narrow width package sizes ranging from 18 mm for the 10 W model, to 72 mm for the 100 W model. Less space on the rail provides additional room for other components or the use of smaller enclosures. The DRL series is suitable for a wide range of industrial applications including building and factory automation, security, process control, and test and measurement.

The DRL series has an operating input range of 85 V_AC to 264 V_AC and can withstand 300 V_AC for 5 seconds. The units have a Class II construction (double insulation) and do not require an earth ground connection.  Input to output isolation is 3,000 V_AC. Four power levels and case sizes are offered (10 W, 30 W, 60 W, and 100 W) with a 24 V output in all package sizes and a 12 V output for the 10 W to 60 W versions. The 30 W to 100 W models have user adjustable outputs from either 12 V to 15 V or 24 V to 28 V.

The convection-cooled units can operate in ambient temperatures from -20°C to +71°C with derating applying at high temperatures. The DRLs are housed in a robust plastic case and share a common depth of 55.6 mm and a height of 91 mm. The 10 W and 30 W have an off-load power draw of < 0.3 W with the 60 W and 100 W at < 0.5 W.

All models certified to UL/CSA 60950-1, IEC/EN 60950-1, and UL 508 with CE marking for the low voltage, EMC, and RoHS₂ Directives. Select models also comply with NEC Class 2 in accordance with UL 1310. All units meet EN55011/EN55022-B conducted emissions (Class A radiated) and comply with IEC 61000-3-2 harmonics and IEC 61000-4 immunity standards.
