The powerful new line of PRO-H power supplies – with ATEX and Class I Div. 2 approvals – was designed for use in Ex zones and high-performance sector. The power supply units – with their high power reserves, wide temperature range from -25 °C to +70 °C, and high MTBF (mean time between failures) of more than 0.9 million hours – are perfect for the process sector, power applications, and demanding machine construction tasks.

Solutions are available to fit control voltages from 12 V/24 V to 48 V. The product can be wired in parallel in order to increase the power capacity. A two-channel setup with 100 % active load sharing can also be implemented with an optional redundancy module. This serves to increase your operational reliability. The Remote On/Off function allows you to switch the device on and off remotely. The output status can be signalled over a voltage-free relay or transistor output. The devices are equipped with pluggable connection terminals which allow them to be easily tested.
Product solutions can be custom-fit for use in different one-phase, two-phase or three-phase mains systems.
- Remote On/Off
The switch-mode power supply can be switched on or off remotely.
- Pluggable connection terminals
The electrical connection, with its pluggable connection terminal, is simple to replace, test or remove (active load sharing).
- ATEX approval
PRO-H switch-mode power supplies have ATEX- and Class I Div. 2 approvals – so they can be used in hazardous areas throughout the world.
- Signalling
The device status can be read either by a potential-free relais contact or a transistor output.
- Parallel connection option
The switch-mode power supplies can be connected in parallel in order to increase their power capacity.
A redundant system with 100 % load sharing can be setup using the optional redundancy module.
- Robust
Thanks to their extended temperature range from –25 °C … +70 °C, the robust switch-mode power supplies
PRO-H can be used under many different environmental conditions.
