DIN rail power supplies suit hazardous locations

The DRF/HL DIN rail mount power supplies certified for use in potentially explosive atmospheres and marine applications have been tested to ISA 12.12.01, IEC/EN 60079-0:2011, IEC/EN 60079-15:2010, and Guidelines for the Performance of Type Approvals — Test Requirements for Electrical/Electronic Equipment and Systems (VI-7-2).

Carrying a five-year warranty, the 24-V output series is available in 120-W, 240-W and 480-W power levels, and can deliver a peak power of 150% for 4 s. The overload characteristic is constant current style, which is appropriate for driving motors and other non-linear loads. The supplies operate from a universal input from 85 to 264 Vac (300 Vac for 5 s) and are compliant to EN61000-3-2. Efficiency levels are as high as 94%. The units can operate at full load from –25° to +60°C (derating linearly to 75% load at +70°C).
