2.3 System Benefits
• Provides clean and continuous power for critical electronic systems to minimize downtime and lost revenue
associated with computer lockups, data losses, hardware failures and power outages.
• Centralized, wall mounted design saves valuable floor space and is easier to maintain and manage.
• Eliminates the need for all remote plug in battery backups, filters, power conditioners, and surge strips which
saves under counter / desktop space.
• Assures that all connected equipment is on the same electrical phase of power for better data communication.
• UPS Bypass Switch (make before break) provides seamless power during UPS maintenance
• Input and output power pilot lights provide for status indication and ease of troubleshooting
2.4 Description of Operation
• 120 Vac, 1 Phase input power supplied to Mac Victor 2.0 from remote supply
(20A for 2kVA or 30A for 3kVA circuit)
• Input circuit breaker provides overcurrent protection for Mac Victor 2.0
(20A for 2kVA or 30A for 3kVA circuit)
• Input Surge Protection Device (hereafter SPD) replaceable module protects Mac Victor 2.0 from surges
• Front Panel mounted Monitor detects open fuses on both Input SPD & Output Surge & Filter Board Assembly
• Input power status light is illuminated when the input circuit breaker is turned on
• Power routed within Mac Victor 2.0 to the Normal / Bypass transfer switch
• In Normal mode:
• Power routed from Normal/Bypass switch to the Mac Victor 2.0 Power receptacle and UPS plug assembly
• UPS provides 120 Vac output with battery backup to UPS receptacle
• Mac Victor 2.0 plug assembly connects to UPS receptacle and returns power back to the Mac Victor 2.0
• Power routed through remote power off relay to the Isolation Transformer with neutral to ground bond
• Output Surge & filter board assembly provides additional surge power protection and noise filtering
• Output Surge & filter board assembly provides signal relays for Input and Output Power remote status
• Output Surge & filter board assembly provides supply power & fuse status signal to panel monitor
• Output power status pilot light is illuminated
• Power routed to 4 output circuit breakers and terminals for field wiring to remote IG power circuits
• (Optional) Power routed to 1 output circuit breaker that powers 4 fully integrated IG receptacle outlets
• (Optional) Remote power off shutdown relay can be added for the integrated IG receptacles
• Mac Victor 2.0 provides dedicated, fully isolated, battery backup source to remote hardwired Isolated
Ground (IG) receptacles and other hard wired equipment
• In Bypass Mode:
• Power is routed from Normal / Bypass switch directly to remote power off relay, bypassing the UPS
• Power is disconnected from the Mac Victor 2.0 Power Plug assembly in the bypass mode
• Output power status pilot light remains illuminated and does not flicker during the transfer since the
switch has “make before break” capability
• Power is routed through the isolation transformer and through the circuit breakers to the isolated ground
receptacles the same as in the Normal Mode operation
• In Remote Power Off (RPO) Mode:
• RPO function is enabled when a jumper feeding the coil of the Remote Power Off relay is removed and
replaced with wiring to the maintained normally closed (N/C) contacts of a Remote Power Off switch.
• When the RPO switch is activated input power feeding the isolation transformer is disconnected by the relay
on both the Line and Neutral conductors which removes power from the IG receptacles and equipment
• When the RPO switch is deactivated input power feeding the isolation transformer is reconnected by the
relay which restores power to the IG receptacles and equipment
