Low Profile Power Supplies Require Less Space on DIN Rail

San Diego, CA – December 2016 –

TDK Corporation announces the introduction of the TDK-Lambda brand DRL 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 18mm for the 10W, to 72mm for the 100W 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 to 264Vac, and can withstand 300Vac 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 3,000Vac. Four power levels and case sizes are offered - 10W, 30W, 60W and 100W – with a 24V output in all package sizes and a 12V output for the 10 to 60W versions. The 30 to 100W models have user adjustable outputs from either 12V to 15V or 24V to 28V.

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

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.

More information and product availability can be obtained on the TDK Product Center, or by calling 800-LAMBDA-4.
