Weidmuller Power Supply PROmax 24V 480W 20 Amp

PROmax Power supply, switch-mode power supply unit, 24 V

PROmax offers diverse solutions for demanding automation.

The high performance and durable PROmax switchmode 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. These 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 the optional uninterruptible DC USPs, the diode modules or CAP modules, you can create a power supply solution that is tailored to your requirements.
