DRF/HL Series DIN Rail Mount Power Supplies

TDK Corporation introduces TDK-Lambda’s DRF120-480 series of full-featured DIN rail mount power supplies. Designed to support the growing trend for DIN power solutions in industrial, building automation, and process-control applications, the DRF series combines extremely compact dimensions with industry-leading efficiency of up to 94%. No-load power consumption is between <0.5 W and <0.75 W depending on the model type.

Carrying a five-year warranty, the TDK-Lambda 24 V output DRF series is available in three power levels, 120 W (5 A), 240 W (10 A), and 480 W (20 A), and can deliver a peak power of 150% for four seconds. The overload characteristic is constant-current style; ideal for driving motors and other non-linear loads. Additional features include remote on/off, parallel capability, remote voltage adjust, and a DC good relay output.

The supplies operate from a universal input of 85~264 V_AC and have EN61000-3-2 compliance, enabling worldwide use; moreover, they can withstand input-voltage surges of 300 V_AC for five seconds.

DRF/HL Series

Featuring IECEx / ATEX and DNV / German Lloyd / Class 1 Div 2 approvals for hazardous and marine applications, the DRF/HL models extend the existing DRF series of 120 to 480 W DIN rail mount power supplies.
