Middle Atlantic ISOCTR-5R – 5RU Isolation Transformer for AV Racks

Product Overview

The Middle Atlantic ISOCTR-5R IsoCenter Isolation Transformer is a 5-rack-unit power conditioning solution designed for commercial AV installations where clean, isolated power is critical. It combines a high-efficiency toroidal transformer with an integrated load center and two-stage surge protection to shield sensitive AV and IT equipment from power anomalies. The ISOCTR-5R is well suited for rack-mount deployments in boardrooms, command centers, broadcast facilities, and data-driven AV systems that require dedicated isolated power circuits.

Product Description

The ISOCTR-5R delivers greater than 98% efficiency through its toroidal transformer design, which produces less heat and electromagnetic interference than traditional laminated-core transformers. The integrated load center includes four 20-amp circuits, all on the same phase, simplifying circuit planning for AV system integrators. Up to eighteen receptacles are available for distributed load connections, giving installers flexibility for dense rack builds without requiring additional power distribution units. Two available input voltages — 208V and 240V single phase — accommodate the majority of commercial building electrical configurations without additional step-down transformers.

A 100,000-amp, two-stage surge and spike protection circuit (on select configurations) shields downstream equipment from transient voltages that cause premature hardware failure. Input voltage monitoring with auto-shutdown functions provides an additional layer of protection, automatically disconnecting the load if incoming voltage falls outside safe operating parameters. The unit occupies 5RU of rack space and is built to Middle Atlantic's commercial-grade standards, making it a reliable power foundation for high-value AV and IT rack systems. The ISOCTR-5R integrates naturally into Middle Atlantic SNE series Slim Network Enclosures and other standard 19-inch rack platforms.

Frequently Asked Questions

Q: What is the difference between an isolation transformer and a standard surge protector?

A: An isolation transformer electrically separates input and output circuits using magnetic coupling, eliminating common-mode noise and ground loops. A surge protector only clamps transient voltage spikes. For sensitive AV and broadcast equipment, isolation transformers provide a significantly cleaner power environment.

Q: Does the ISOCTR-5R work with standard 120V circuits?

A: No. The ISOCTR-5R accepts 208V or 240V single-phase input only. It is designed for commercial AV installations with higher-voltage feeds typical in commercial buildings. Consult a licensed electrician to confirm your facility's available circuits before ordering.

Q: Can the ISOCTR-5R be installed in a Middle Atlantic SNE series enclosure?

A: Yes. The ISOCTR-5R uses a standard 19" rack-mount form factor and is compatible with Middle Atlantic SNE series Slim Network Enclosures and other standard rack systems.

Q: Is professional installation required?

A: Yes. Connections to 208V or 240V single-phase circuits must be performed by a licensed electrician in accordance with local electrical codes.
