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).
