Modularity reduces the risk of wasteful oversizing at installation, while offering “pay as you grow” scalability when it’s time to expand, optimising initial investment and total cost of ownership (TCO).

It is designed to protect:

  • any critical high-density computer and IT environment
  • data centres
  • critical loads

Multi bypass

The Multi Pass manual bypass cuts out UPS in the event of malfunction or breakage. Multi Pass permits that the connected consumers are switched to mains power before a UPS is switched off or before make maintenance. Multi Pass is available for rack or wall installations (box).

Multi Switch

Automatic Transfer Switch

The Riello UPS Multi Switch is a high availability and versatile intelligent switch that provides redundant power to connected equipment with two AC input sources. The Riello UPS Multi Switch supplies power to the connected loads from a primary mains source. If that primary source becomes unavailable, the Riello UPS Multi Switch automatically transfers loads to the secondary source.

According to the ITI (CBEMA) chart, the transfer time from one source does not impact the operation of the connected equipment as the switching occurs safely between the two input sources regardless of any phase differences. The Riello UPS Multi Switch monitors the current and provides warnings when power consumption draws near the maximum rating which helps prevent downtime to the equipment.

Riello UPS Multi Switch has 8 independent IEC 10 A outlets allowing several devices can be plugged directly into the Rack without the need for an additional Rack PDU. The units have a connectivity slot which allows for LAN connection and remote management through PowerShield3 software, Web interface, SNMP, or SSH which makes the Riello UPS Multi Switch an ideal device for the IT manager who needs flexibility and protection for their IT equipment.

Multi Switch provides installations with power supply continuity. Its operating principle ensures higher reliability than a single UPS, (with or without its own internal bypass).

Multi Switch ATS

Automatic Transfer Switch Riello UPS Multi Switch ATS is a high availability intelligent switch that provides redundant power to connected equipment with two AC input sources. Multi Switch ATS supplies power to the connected loads from a primary mains source. If that primary source becomes unavailable, Multi Switch ATS automatically transfers loads to the secondary source.
