ModularEasy
Pulsar MX ModularEasy enables parallel
operation when combining two Pulsar MX
UPSs. Consequently you can enhance the
availbility level of your equipment (N+1
redundancy). You can also double your
secured power capacity according to your
needs (migration, network extension...).
In the unlikely event a major fault would
occur, the manual maintenance bypass of
Pulsar MX ModularEasy would allow the
UPS maintenance without interrupting your
connected equipment.
In single unit mode, Pulsar MX
ModularEasy combined with one Pulsar MX
UPS adds a second level of availability to
your installation.
The manual bypass mode allows the
replacement of the UPS without any
interruption to the connected equipment in
case of a major fault that would not be related
to the most critical components of the UPS
(i-e front-accessible, hot-swappable Battery
and Power Sub-Modules).
