Compact DIN rail power supply

February 2019 Electrical Power & Protection

TDK Corporation has announced the introduction of the TDK-Lambda brand DRF960-24-1 DIN rail mount AC-DC power supply, rated at 24 V 40 A (960 W) with a 60 A (1440 W) peak for 4 seconds. The product has a narrow (110 mm) width, freeing additional space for other DIN rail assemblies. With an efficiency of 95%, significantly less internal heat is generated with operating field life calculated at greater than 10 years at 75% load, 40°C ambient, and 230 VAC input. This energy efficient power supply is suitable for a wide range of industrial applications including factory automation, process control and test and measurement equipment.

The 24 V output is adjustable from 24-28V, using the front panel potentiometer or an external 5-6 V DC source to compensate for blocking diodes or FETs in redundant configurations. Also provided as standard is a DC OK relay contact and remote on/off functionality. Up to five units can be connected together in parallel when set in droop mode current share.

The supply is housed in a robust metal enclosure and can operate from a wide 180-264 V AC input. It is rated for operation in -25 to 70°C ambient temperatures, derating linearly above 60°C to 50% load at 70°C.

The unit is safety certified to IEC/EN/UL/CSA 60950-1, UL 508 and CE marked for the Low Voltage, EMC and RoHS Directives. It meets EN 55032-B radiated and conducted emissions, and complies with the EN 61000-4 immunity standards.
