  • The Middle Atlantic IsoCenter® Rackmount Isolation Transformer System provides protected, same-phase, isolated 120VAC circuits to power your AV systems. Many electrical issues can arise when designing a system, including ground loops and common-mode/differential-mode high frequency noise. These problems can arise from poor or improper wiring techniques and from equipment designed with lesser quality common-mode rejection ratio (CMRR). Equipment problems cannot always be resolved, but the IsoCenter system helps prevent the negative effects of all these problems.

    Operating at efficiencies greater than 98% and performing an automatic shutdown if hazardous input voltage conditions are detected The IsoCenter provides the critical foundation for optimal system performance. A newly derived AV reference ground helps prevent ground loops and provides the lowest possible noise floor for high gain applications. Negligible audible noise & negligible magnetic leakage (less than half that of a standard power brick) means that the IsoCenter can be installed directly inside the equipment rack, where it is most beneficial.

    Master Power 2-Pole Circuit Breaker:
    Switches the main power on and off to the primary side of the isolation transformer provides 25A at 208V of over-current protection.

    Surge Protection:
    100,000Amp 2-stage surge and spike protection with dry contact status notification.

    Load Center Breakers:
    Provides four circuits of 20A over current protection to the designated banks of receptacles on the back of the unit.

    External Ground / Bonding Bus:
    An external ground bus is located at the rear of the unit in order to provide a termination point for establishing a low impedance single point grounding system (SPG) for the rack enclosure and connected equipment. This bus is a seven (7) position grounding terminal strip (screw type).

    Includes a Toroidal isolation transformer, with a 98% high efficiency type with a proprietary alloy core, a single 120V secondary winding (all circuits on the same phase) with a Faraday shield.

    The IsoCenter system is housed in a rack mountable steel enclosure with a built in rear rail telescoping support. Overall dimensions: 7" high (4RU), 14.4" deep, 19" wide at the mounting ears and 17.5" wide at the chassis body, enclosure is black powder coat.

    Power In-feed:
    Feeder circuit is pluggable. The unit is fed via a fixed molded "twist-lock" male plug (NEMA configuration L6-30P) and 10° long power cord. A 30A Single Phase feeder circuit is required.

    Power output Receptacles:
    The receptacle branch circuits are made up of eighteen (9 duplex) 20A specification grade gray receptacles, NEMA configuration is 5-20R. The receptacle labels are laser engraved indicating the circuit identification and bank arrangement.

    Remote Branch Circuit Extension:
    Hardwire up to two remote branch circuits directly to unit.

    Maximum Load:
    The maximum load shall not exceed 41.66A @ 120V (5000 Volt-Amperes) continuous. A de-rating factor of 80% may be required under certain conditions of installation and/or NEC Requirements.

    All control circuits and relays are grouped onto two printed circuit boards with terminal strip connections for all wiring points.
