Isolated Power Systems: Multiple Configurations

Isolation power systems support safe, NEC‑compliant operating room power distribution. Standard systems serve single ORs, duplex systems provide dual capacity and future expansion, dual voltage systems deliver 120V and 208V from one feed, and controlled systems centrally manage 208V power to multiple locations using PLC‑controlled, modular designs. Additional information can be found in the Iso-Gard Series 6 Line Isolation Monitor (LIM) Catalog, Document Number 4805CT1301.

Standard Isolation System

Standard System offer the most compact solution for a single isolated power system feeding one operating room.

• Designed to support either 120 or 208 V power requirements in the operating room

• 120 V Systems are available in 3, 5, 7.5, and 10 kVA designs

  • Space for 16 branch circuits

• 208 V Systems are available in 7.5, 10, 15, and 25 kVA designs

  • Space for 16 branch circuits

Duplex Isolation Systems

Duplex Systems allow for two standard systems to be mounted in a common backbox and use a common trim. Backbox is barrier to keep the two-system separate. Requires two unique feeds. Solution also offers one side to be design for future space.

• Designed to support either 120 or 208 V power requirements in the operating room

• 120 V Systems are available in 3, 5, 7.5, and 10 kVA designs

  • Space for 16 branch circuits

• 208 V Systems are available in 7.5 and 10 kVA designs

  • Space for 16 branch circuits

Dual Voltage Isolation System

Dual Voltage System are designed to feed both 120 and 208 V power via one Isolation System. Incorporate a transformer with one primary winding and two secondary windings. Supply via One Feed.

• Designed to support both 120 and 208 V power requirements in the operating room

• 120 V Systems are available in 5, 7.5 and 10 kVA

  • Space for 16 branch circuits

• 208 V Systems are available in 7.5 and 15 kVA

  • Space for four branch circuits

Controlled Isolation System

Controlled Systems are designed to provide 208 V of isolated power to multiple areas from one central location. A programmable logic controller (PLC) lets the system be designed to feed multiple load location, but only provide power to specific power modules. This helps prevent overloading of the system, and compliance with 200,000 resistance requirements of NEC, since the PLC limits number of circuits. (Default is one circuit energized)

• Designed to support 208 V power requirements for multiple locations

  • Options for 4, 8, or 12 branch circuits – preconfigured at the factory

• Modular Design provides maximum flexibility and easy for upgrading and changing the system

Interiors: Line Isolation Monitor, Line Isolation connector terminal, 125 Amp 250 V NQ panelboard with copper bus, Dead front, Space for Main Breaker (field installed), allocated space for field installed accessory.
