Middle Atlantic 8in. in. MPR 20A ISO CONT.MOD - RLM-20IGA

Middle Atlantic RLM-20IGA Isolated Ground Rackmount Power Control Module

Overview

The Middle Atlantic RLM-20IGA is a single-circuit, 20-amp isolated ground power control module designed to slot into Middle Atlantic's MPR (Modular Power Rackmount) chassis systems. If you're building a rack where sensitive electronics — NVRs, encoders, managed switches, DSPs — need clean, noise-isolated power without compromising overcurrent protection, the RLM-20IGA addresses that requirement at the circuit level rather than forcing you to manage it externally. At 8 inches deep (20.3 cm), it fits standard mid-depth rack enclosures without crowding cable management lanes.

The RLM-20IGA (often searched as RLM 20IGA) gives integrators a modular path to power distribution: instead of deploying a fixed-outlet strip that can't be reconfigured, you populate an MPR chassis with the specific circuit types your project requires — controlled, isolated-ground, or standard — and swap them out if the deployment changes. That flexibility is the core value proposition of the MPR platform, and this module is its heavy-duty 20A controlled entry point.

Key Features

• 20A Circuit Rating at 120 VAC: A single 20-amp circuit handles high-draw loads like UPS bypass paths, PoE injectors, or multi-drive NVRs that would trip a 15A module under sustained load. Spec your circuit to the actual device draw — don't leave headroom to chance.
• Isolated Ground: The isolated ground path physically separates the ground conductor from the chassis ground, which matters in AV and security racks where ground loops introduce 60Hz hum into audio, create noise in IP video streams, or trigger false alarms in sensitive detection systems. If you've spent hours chasing hum in a hybrid AV/security rack, this is the module that eliminates the root cause rather than masking it.
• Controlled Output: The controlled designation means this module participates in the MPR chassis's sequenced power switching — you can assign power-on/off order across modules, preventing inrush current spikes when bringing up a full rack. A rack with multiple controlled modules staggers load application rather than hitting the panel breaker with simultaneous inrush from every device.
• Configurable Power (Special Feature): Within the MPR system, configurable power means outlet grouping and control parameters can be adjusted to match the operational requirements of the devices on that circuit — useful when security system integrators need to isolate IP cameras or video recorders on their own controllable circuit segment separate from network infrastructure.
• Corded Cable Type: The module ships with a corded connection, integrating into the MPR chassis wiring harness rather than requiring field termination. This simplifies installation in time-sensitive deployments and keeps rack wiring organized without additional cable management hardware.
• ETL Recognized: ETL recognition (by Intertek) confirms the module has been tested to NRTL safety standards — equivalent standing to UL listing for commercial AHJ sign-off. Most commercial building inspectors and IT procurement teams require a recognized listing mark; ETL satisfies that requirement.
• 8-Inch Depth (20.3 cm): Shallow enough to fit mid-depth rack enclosures common in IDF closets, security head-end rooms, and wall-mount two-post racks without interfering with rear cable management. Measure your available depth before spec'ing deeper alternatives.

Integration & Compatibility

The RLM-20IGA is engineered for use within Middle Atlantic's Middle Atlantic MPR rackmount power chassis product line. It is not a standalone power strip — it requires a compatible MPR chassis slot to function. If you're configuring a new rack build, pair this module with the appropriate rackmount power distribution chassis that supports 20A modular slots. Consult Middle Atlantic's MPR chassis compatibility matrix to confirm slot count and amperage budgeting before ordering multiples of this module on a shared 20A feed.

For security deployments, the isolated ground feature is particularly relevant when co-locating IP video recorders, managed network switches, and access control panels in the same rack — equipment classes that are sensitive to ground-induced noise but must share physical rack space. Pair this module with a proper rack enclosure that supports Middle Atlantic's MPR chassis form factor for a complete power management solution.

Note: TAA compliance is not applicable for this SKU. If your project is subject to federal procurement requirements mandating TAA-compliant power distribution, verify with your procurement team before specifying the RLM-20IGA.

Frequently Asked Questions

Q: What is the purpose of the isolated ground on the RLM-20IGA?

A: The isolated ground separates the ground conductor from the rack chassis ground. This prevents ground loops that cause 60Hz hum in audio systems and noise artifacts in IP video — common problems when AV, security, and network equipment share a rack. It's particularly valuable in hybrid security/AV head-end rooms.

Q: Does the RLM-20IGA work as a standalone power strip?

A: No. The RLM-20IGA is a modular power control module designed to install into a compatible Middle Atlantic MPR chassis. It requires the chassis to function and cannot be used independently as a standalone unit.
