MHD Modular
MHD Modular
The MHD Modular is a scalable online double-conversion
UPS and with up to 6 modules it can be congured to
4kVA, 8kVA, 12kVA, 16kVA, 20kVA and 24kVA.
One of the most important advantages of the
modularand redundant design is the improved safety
and reliability. If the MHD Modular is congured to
N+X parallel- redundancy, the load is instantaneously
redistributed among the remaining modules. Because
each module is a seperately operating device, there is
no central control system that could be damaged, so this
also increases the safety.
The MHD Modular has got hardwired outputs with one
phase and can be used with one or three phase inputs
alternatively. In case of operating with three phases,
each of them is monitored by the UPS.
Additional modules can be installed to the MHD Modular
during normal operation without much time and effort.
This hot swappable methode provides subsequent
extension of the UPS system without any disturbance of
normal operation of the users, so this
system provides sang of costs. Also the possibility
to change defective modules during normal operation
without any disturbance of the users leads to more
sang of costs.
