The new STEP POWER generation of compact power supply units is particularly suitable for installation distributors
and flat control panels thanks to its design. The power supply units are available with 24 V DC output voltage in various
performance classes and widths and with the special voltages 5, 12, 15 and 48 V DC. Their high degree of efficiency and
the low standby losses make for high power efficiency.
