Order No. 1478100000
Version Power supply, switch-mode power supply unit, 24
V
GTIN (EAN) 4050118286021
Qty. 1 pc(s).
PROmax offers diverse solutions for demanding
automation.
Our high performance and durable PROmax switch-
mode power supply units are designed for especially
demanding requirements. PROmax reliably copes with
continuous overload of up to 20% or short-term peak
loads of 300% occurring with high control cabinet
temperatures.
High boost capability and full power are also made
possible in a wide temperature range. Our switch-mode
power supply units can be used around the world and
are also suitable for confined spaces thanks to their low
width.
Together with our uninterruptible DC USPs, the diode
modules or CAP modules, you can create a power supply
solution that is tailored to your requirements.
