Middle Atlantic Thermostatic FAN Controller W/iec Receptacles - FC-4-IEC

Middle Atlantic FC-4-IEC Thermostatic Fan Controller with IEC Receptacles

Overview

The Middle Atlantic FC-4-IEC is an active thermostatic fan controller built for 220VAC rack environments where you need automatic, temperature-driven airflow management across up to four fans. Rather than running fans at full speed continuously — wasting energy and accelerating bearing wear — the FC-4-IEC modulates fan operation in response to actual rack temperatures, bringing a measurable operational benefit to AV equipment rooms, broadcast facilities, and any rack thermal management installation running on European or international power standards.

At 4 inches wide and 8.69 inches tall, the FC-4-IEC fits cleanly into a standard rack bay alongside other Middle Atlantic rack accessories. The 3.33-inch depth keeps it from encroaching on cable management space at the rear of the rack. If you're specifying rack thermal management and need a unit that won't dominate the rack profile, the physical footprint here is practical.

Key Features

• Active Thermostatic Control: The FC-4-IEC uses active (not passive) temperature sensing to trigger and regulate fan operation. This means fans only run — or run harder — when heat actually builds up. In a 24/7 equipment room, that translates to quieter operation during off-peak hours and extended fan service life compared to always-on configurations.
• 4 Controlled Fan Outputs: Supports up to four independent fans, giving you enough capacity to manage multi-fan rack configurations without a second controller. For a rack cooling build with intake and exhaust fans on separate sides of the rack, four outputs covers most standard deployments without daisy-chaining or splitting circuits externally.
• 220VAC Operation: Rated for 220VAC, the FC-4-IEC is the correct unit for international installations, EU-standard facilities, or any U.S. site running on 220V branch circuits (common in AV and broadcast infrastructure). If your rack is on 120VAC North American power, this is not the right model — verify your supply voltage before ordering.
• IEC Receptacles: Fan connections use IEC-format receptacles rather than flying leads or proprietary connectors. IEC connectivity simplifies field replacement of individual fans without re-wiring the controller, and it ensures compatibility with the broad range of rack fans that ship with IEC power cords as standard.
• Compact, Rack-Friendly Dimensions: At 4 in (W) × 8.69 in (H) × 3.33 in (D), the FC-4-IEC slots into rack bays without consuming excessive real estate. The 8.69-inch height fits within standard rack unit allocations, keeping your thermal management gear from eating into equipment space.
• TAA Non-Compliant: The FC-4-IEC is not TAA compliant. For U.S. federal government procurement subject to Trade Agreements Act requirements, this unit does not qualify. Non-federal commercial and international deployments are unaffected.

Integration & Compatibility

The FC-4-IEC is designed for use within Middle Atlantic rack systems and integrates with standard IEC-connected rack fans. Because it operates at 220VAC, it pairs naturally with international power distribution units (PDUs) and rack infrastructure in EU and Asia-Pacific deployments. Installation into a rack power distribution setup is straightforward: connect the controller to a 220VAC feed, then connect up to four IEC-equipped fans to the output receptacles. The active thermostatic circuit handles the rest without requiring software configuration or network integration — it is a standalone, hardware-only thermal management solution.

The FC-4-IEC (often searched as FC 4 IEC) does not require a network connection, driver installation, or VMS integration. It operates independently of any building management system, making it suitable for deployments where simplicity and reliability matter more than remote monitoring.

Frequently Asked Questions

Q: What voltage does the FC-4-IEC operate on?

A: The FC-4-IEC is rated for 220VAC. It is not designed for 120VAC North American standard circuits. Verify your rack's supply voltage before ordering.

Q: How many fans can the FC-4-IEC control?

A: The FC-4-IEC supports up to four fans simultaneously via its IEC receptacle outputs.

Q: Is the FC-4-IEC TAA compliant?

A: No. The FC-4-IEC is not TAA compliant and is not eligible for U.S. federal procurement under Trade Agreements Act requirements.

Q: What type of connectors does the FC-4-IEC use for fan connections?

A: The FC-4-IEC uses IEC-format receptacles for fan connections, which simplifies fan replacement and is compatible with most standard rack fans that ship with IEC power cords.

Q: Does the FC-4-IEC require any software or network configuration?

A: No. The FC-4-IEC is a standalone, hardware-only thermostatic controller. It requires no software, network connection, or external configuration — it operates autonomously based on rack temperature.

Q: What are the physical dimensions of the FC-4-IEC?

A: The FC-4-IEC measures 4 in wide × 8.69 in tall × 3.33 in deep (10.2 cm × 22.1 cm × 8.5 cm).

Ted Perry

The FC-4-IEC is Middle Atlantic's answer to a specific and often overlooked problem: 220VAC rack environments where you need thermostatic fan control without running four fans at full tilt around the clock. I've seen plenty of international AV and broadcast installations where the integrator just wires fans to a switched outlet and calls it done — the FC-4-IEC is the right way to handle this, using active thermostatic control to bring fans up only when rack temps actually demand it.

Technical Highlights:

• 220VAC Rating: Correct fit for EU, Asia-Pacific, and international 220V infrastructure — this is the spec that determines whether this controller belongs in your project at all. North American 120VAC racks need a different unit.
• 4 IEC Outputs: Four individually receptacled fan connections mean you can mix intake and exhaust fans in a single rack bay without splitting a circuit or adding a second controller. IEC connectors also make field fan swaps clean — unplug, replace, done.
• Active Component Type: The active thermostatic circuit actively measures and responds to temperature changes rather than relying on a fixed timer or manual switching. In a 24/7 equipment room, this is the difference between fans that last years and fans that burn out in months.

Deployment Considerations:

• Confirm supply voltage is 220VAC before install — the FC-4-IEC has no auto-ranging capability. Installing it on a 120VAC circuit is a wiring error, not a configuration option.
• TAA non-compliance is a hard stop for U.S. federal and GSA-schedule procurement. Flag this early in the RFQ process if your customer has government contracting requirements.

The FC-4-IEC is the right specification for international AV system integrators building rack enclosures in EU or Asia-Pacific facilities — specifically broadcast control rooms, AV equipment closets, and any 220V rack build where automated thermal management needs to happen without any network or software dependency.
