PRO-H
Advantages
 Best in Class by:
- Space saving installation in the cabinet by very small housing
- Robust and Powerful: Wide temperature range from -25°C…+70°C with additional
power reserve at standard temperature
- International applicable by wide input range and by comprehensive approvals like
UL, CSA and ATEX
- Simple power increasing by parallel connection without diode module
- Redundancy with 100% load sharing with additional Redundancy module
- For each application the right power supply:
• 1-phase: 2A up to 25A
• 2- or 3-phase: 7,5A up to 40A
• Output voltage: 12,24,36 and 48VDC
- Reliable power supply by high hold up time
- External Signalising of the output with potentialfree relay or transistor
- External Switch Off with Remote Input.

 cULus, cCSAus, C1D2, C1 Zone 2, ATEX
 Space Saving
 35 mm wide 15A version and 54 mm wide 25A version
PRO-H Redundancy Modules – What do they exactly do?
 Create a redundant 24V DC power system in hazardous
locations.
 Equal sharing of the output current by each power supply.
 System maintaining uninterrupted power to the critical
load even if one power supply fails due to internal fault or
loss of its AC input, as second power supply will
automatically supply full current.
 System monitoring with alarm output in case of loss of
redundancy.
 Connections are hot swappable for easy and quick
replacement without disturbing the load.
