Product Description

The KEN 24 series comprises power supply units designed for 35 mm DIN rail mounting and are available in 5 A, 10 A or 20 A versions. The unit generates a galvanically isolated 24 VDC output (SELV) from an input AC voltage of 100 VAC to 240 VAC. The power supplies are protected against overheating, overload and short circuits, and operate within a wide temperature range of -40°C to +70°C. The units combine industrial robustness with a compact design and high efficiency.
