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).
