Product Description

STEP POWER power supplies – for building technology
Due to their design, the flat power supplies are particularly suitable for distribution boards 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.
