DIN rail power supply unit 24 V DC/3.5 A, primary switched-mode, 1-phase.

Product Description

STEP POWER power supplies - for building technology

Due to their design, the flat power supplies are particularly suitable for installation distributors and flat control panels. The power supply units are

available with 24VDC output voltage in various performance classes and overall widths as well as special voltages 5, 12, 15, and 48VDC. Their

high degree of efficiency and low standby losses ensure a high level of energy efficiency.

Why buy this product

Flexible mounting by simply snapping onto the DIN rail or screwing onto a level surface

Reliable power supply thanks to high MTBF (mean time between failures) of more than 500,000 hours and U/I characteristic curve

Energy savings thanks to maximum energy efficiency and incredibly low idling losses
