Middle Atlantic M 1U 16A 120V(8)5-20R L5-20P - LP-41210

Middle Atlantic LP-41210 1U Horizontal Rackmount Power Distribution Unit

Overview

The Middle Atlantic LP-41210 is a 1U horizontal rackmount PDU delivering 20 amps at 120 VAC across eight NEMA 5-20R receptacles — a straightforward, reliable power distribution solution for security enclosures, network racks, and AV equipment bays where clean, organized power delivery matters more than exotic features. If you're populating a rack with NVRs, managed switches, encoders, or access control panels that draw under 2A each at 120V, this unit covers the load without overcrowding the power budget. The LP-41210 (often searched as LP 41210) ships with a 9.84 ft (3 m) corded L5-20P twist-lock plug — the standard 20A locking connector found on most UPS bypass outputs and dedicated 20A wall circuits in equipment rooms.

Key Features

• Eight NEMA 5-20R Receptacles at 20A Total: Eight outlets on a single 20A branch circuit gives you enough ports for a full NVR stack, a PoE switch, and ancillary security hardware without daisy-chaining strips. Keep in mind the NEC 80% continuous-load rule — plan your connected draw at 16A or under for 24/7 operation.
• L5-20P Twist-Lock Input Plug: The locking L5-20P input connector won't accidentally pull out of a UPS output or dedicated 20A receptacle under vibration or cable tension — a real consideration in equipment rooms where cable management is tight and accidental disconnects mean downtime.
• 1U Horizontal Form Factor (17.2 in W × 1.7 in H × 5.2 in D): At 1.7 inches tall, the LP-41210 occupies a single rack unit. The 5.2-inch depth keeps it well clear of rear cable managers in standard 24- to 30-inch deep enclosures, leaving cabling room behind the unit without forcing awkward bends.
• 9.84 ft (3 m) Input Cord: A 3-meter cord reaches from a rack-mounted UPS output or a floor-level 20A receptacle to the PDU without extension cords — useful in server rooms where the power source is across the aisle or at the base of the cabinet.
• 120 VAC / 20A Input: Sized for standard North American 20A dedicated circuits. This is not a 208V or 240V unit — confirm your circuit voltage before ordering. It's the right fit for facilities running 120V branch circuits off an L5-20 UPS, which covers most small-to-mid enterprise deployments.
• TAA Compliant: Meets Trade Agreements Act requirements, qualifying this PDU for federal procurement, GSA schedules, and government-funded security infrastructure projects where TAA compliance is a bid requirement.
• Black and Silver Finish, Horizontal Mounting: The dual-tone finish fits standard rack aesthetics. Horizontal mounting means outlets face forward or rear (confirm orientation for your enclosure) and the unit slides into any EIA-standard 19-inch rack without adapter brackets.
• 5.99 lb Shipping Weight: Light enough for a single technician to install during rack build-out without a lift or second set of hands — relevant when you're commissioning multiple racks in sequence.

Integration and Compatibility

The LP-41210 fits any standard 19-inch EIA rack and pairs directly with Middle Atlantic enclosures, third-party relay racks, and open-frame two-post racks. The L5-20P input connects to any 20A NEMA L5-20R receptacle, including outputs found on common UPS units used in security and AV installations. All eight NEMA 5-20R outlets accept standard two- and three-prong 5-15P and 5-20P plugs, covering virtually every piece of rack-mounted security and network hardware on the market. This unit does not include surge suppression, remote monitoring, or individual outlet switching — if those capabilities are required, evaluate higher-tier PDUs in the Middle Atlantic power distribution line. For deployments requiring monitored or switched outlets, plan accordingly at the design stage rather than retrofitting. Browse the full range of rack PDUs and power distribution units to compare capacities and feature sets. If your rack design includes PoE switches drawing significant aggregate power, reference our PoE power planning guide to validate branch circuit sizing before specifying this or any 20A PDU.

Frequently Asked Questions

Q: Is the LP-41210 TAA compliant for government procurement?

A: Yes. The LP-41210 is TAA compliant, making it eligible for federal agency purchases, GSA schedule orders, and other government-funded projects that require Trade Agreements Act conformance.

Q: What input plug does the LP-41210 use, and what circuit does it require?

A: The LP-41210 uses an L5-20P twist-lock input plug and requires a dedicated 20A, 120 VAC circuit with an L5-20R receptacle. It is not compatible with 208V or 240V circuits.

Q: How many devices can I connect to the LP-41210?

A: The LP-41210 provides eight NEMA 5-20R receptacles. For 24/7 continuous operation, plan total connected load at no more than 16A (80% of the 20A rating) per NEC continuous-load guidelines.

Q: Does the LP-41210 include surge protection or remote monitoring?

A: No. The LP-41210 is a basic corded rackmount PDU without surge suppression, individual outlet switching, or remote monitoring. If those features are needed, evaluate higher-tier PDUs in the Middle Atlantic line.

Q: What rack size does the LP-41210 fit?

A: The LP-41210 mounts horizontally in any standard 19-inch EIA rack, occupying 1U (1.7 inches of rack height). Its 5.2-inch depth is compatible with standard 24- to 30-inch deep rack enclosures.

Q: What is the cord length on the LP-41210?

A: The input cord is 9.84 feet (3 meters), long enough to reach from a rack-mounted UPS or floor-level 20A receptacle without requiring extension cords in most standard equipment room layouts.

Marty Allison

The LP-41210 is the PDU I reach for when a project calls for a reliable 20A/120V horizontal strip with a locking input and enough outlets to cover a full security rack without overcomplicating the power design. Eight NEMA 5-20R receptacles on a single 20A circuit, L5-20P twist-lock input, 1U profile — it does exactly what it says and nothing more, which is often exactly what you need.

Technical Highlights:

• L5-20P Twist-Lock Input: The locking plug eliminates accidental disconnects at the UPS output — a failure mode I've seen take down surveillance recording in facilities where cable management is dense and techs are working fast.
• Eight NEMA 5-20R Outlets on 20A: Enough capacity for an NVR, managed PoE switch, access control panel, and several ancillary devices. Budget your continuous draw at 16A or under — the NEC 80% rule applies to every 20A circuit running 24/7.
• 1U × 5.2-inch Depth: Fits inside standard 24-inch deep Middle Atlantic enclosures with room behind it for structured cabling. At 5.99 lbs shipped, one tech handles the install without assistance.

Deployment Considerations:

• The 9.84 ft (3 m) cord is generous for most rack setups, but verify your UPS output receptacle type before ordering — this unit lands on an L5-20R, not a standard 5-20R duplex. Mismatched receptacles are a common field delay on first-time installs.
• This is a non-monitored, non-switched PDU. If your project spec requires per-outlet current monitoring, remote reboot capability, or surge suppression, this unit is not the right fit — step up to a monitored PDU in the Middle Atlantic lineup at the design phase, not after rack build.

The LP-41210 is the right call for compact security or AV racks in enterprise branch offices, school security closets, and municipal facility equipment rooms where the circuit is 120V/20A, the load profile is moderate, and the budget doesn't justify a monitored strip. Straightforward to commission, TAA-clean for government bids, and proven in Middle Atlantic enclosures.
