Vertiv MP2-130C 2U Micropod Bypass Panel for PSI5-3000RT120 UPS
Overview
The Vertiv MP2-130C is a 2U rack-mount micropod bypass panel engineered specifically to support the PSI5-3000RT120 UPS in 120V single-phase environments. Where most bypass solutions require rewiring or a dedicated electrician during maintenance windows, the MP2-130C lets you safely take a UPS offline — for service, battery replacement, or swap-out — while keeping downstream loads on utility power without dropping a single outlet. That's the core value proposition: planned maintenance without unplanned downtime.
The MP2-130C (often searched as MP2 130C) occupies a clean 2U of rack space and ships in black to match standard rack aesthetics. It is part of the Vertiv Micropod bypass family, which covers a range of PSI5 UPS models and input configurations — make sure you're matching the right variant to your UPS model and facility wiring before ordering.
Key Features
- L5-30P Input Plug: The twist-lock NEMA L5-30P input is the standard for 30A/120V rack power distribution — it plugs directly into the PSI5-3000RT120's output receptacle without adapters or custom wiring. If your UPS has a 5-20P or hardwired output, that's a different Micropod variant (MP2-120C or MP2-120HW respectively); the L5-30P is specifically matched to the 3000VA-class PSI5 models.
- Eight NEMA 5-15/20R Outlets: Eight combination 5-15/20R receptacles accept standard 15A and 20A plugs interchangeably — relevant when you're mixing 1U servers (typically C13/5-15 loads) with higher-draw appliances. Eight outlets is enough for a dense 2U bypass serving a typical edge rack or server shelf.
- 24A Maximum Current: At 24A on a 30A circuit, the MP2-130C operates at 80% of circuit capacity — the NEC-recommended continuous load ceiling. This isn't marketing math; it's the code-compliant design limit that prevents tripping under sustained load. Size your connected load accordingly before commissioning.
- 120V / 50–60Hz Operation: Nominal 120V input and output with 50–60Hz frequency compatibility covers both US 60Hz utility and facilities with generator or UPS output that may vary slightly. The MP2-130C is strictly a 120V device — it is not suitable for international 230V deployments.
- UL1778 and c-UL Listed: UL1778 is the UPS equipment standard; c-UL extends that listing to Canadian jurisdictions. These certifications matter for data center and commercial facility compliance sign-off — they're required by many AHJs (Authorities Having Jurisdiction) before a bypass panel can be installed in a managed rack environment. ISTA Procedure 1A listing covers transport testing, relevant if the unit ships to a remote site.
- 0–95% Operating Humidity (Non-Condensing): The full 0–95% RH operating range means the MP2-130C won't need derating in humid machine rooms or facilities without precision cooling — a practical spec for edge deployments in warehouses or manufacturing environments where climate control is less precise.
- 32–104°F (0–40°C) Operating Temperature: Standard commercial operating range. The 104°F upper limit is appropriate for conditioned data rooms and IDF closets; it's not rated for ambient temperatures above that, so don't install it in an uncooled outdoor cabinet.
- 2U, 432mm Wide Rack Form Factor: Standard 19-inch rack width at 432mm and 2U height integrates into any EIA-310 rack without rail kits or shelf adapters. The 89mm depth keeps the unit shallow — relevant in shallow-depth wall-mount enclosures or two-post open-frame racks where depth clearance is constrained.
Integration and Compatibility
The MP2-130C is designed exclusively for the Liebert PSI5-3000RT120 — Vertiv's 3000VA/2700W 120V rack UPS. It does not support the 1500VA PSI5 models (those use the MP2-115 series) or the 2200VA model (MP2-120 series). Confirm your UPS model number before ordering; the Micropod family covers multiple input/output configurations and an incorrect variant will not physically mate with your UPS's output receptacle.
From an rackmount UPS accessories standpoint, the bypass panel sits between the UPS output and the rack PDU or directly-connected loads. No additional hardware or software integration is required — this is a passive bypass switch, not a managed PDU. It does not provide SNMP monitoring, switched outlets, or remote management capability. If remote power management is a requirement, that belongs at the PDU layer downstream.
Frequently Asked Questions
Q: Which UPS models are compatible with the MP2-130C?
A: The MP2-130C is compatible exclusively with the Vertiv Liebert PSI5-3000RT120. It is not compatible with 1500VA or 2200VA PSI5 models — those require the MP2-115 or MP2-120 series respectively.
Q: What is the input plug type on the MP2-130C?
A: The MP2-130C uses a NEMA L5-30P twist-lock input plug, designed to connect directly to the PSI5-3000RT120's output receptacle. Do not attempt to use this bypass panel with a UPS that has a NEMA 5-20P or hardwired output — a different Micropod variant is required for those configurations.
Q: How many outlets does the MP2-130C provide, and what types?
A: The MP2-130C provides 8 outlets, all NEMA 5-15/20R combination receptacles. These accept both standard 15A (5-15P) and 20A (5-20P) plugs without adapters.
Q: What is the maximum current rating of the MP2-130C?
A: The maximum current rating is 24A. This represents 80% of the 30A circuit capacity — the NEC-recommended continuous load limit. Do not exceed 24A of connected load.
Q: Is the MP2-130C UL listed?
A: Yes. The MP2-130C carries UL1778 and c-UL listings, as well as ISTA Procedure 1A certification for transport testing. UL1778 and c-UL listings are typically required by commercial facility AHJs for UPS bypass equipment installation approval.
Q: Can the MP2-130C be used in a 230V international installation?
A: No. The MP2-130C is rated for 120V nominal input and output only. It is not suitable for 230V international deployments. Vertiv offers separate Micropod variants for other voltage configurations.
The MP2-130C is a purpose-built bypass solution and the key detail to get right before ordering is the 24A maximum current ceiling — that's your real design constraint on a 30A L5-30P circuit, and it limits how densely you can load the eight 5-15/20R outlets downstream. I've seen installs go sideways when someone assumes the full 30A is available and commissions eight 3A average loads without accounting for inrush on server startup sequences.
Technical Highlights:
- L5-30P to 8x 5-15/20R Configuration: The twist-lock input mates directly to the PSI5-3000RT120's output — no pigtail adapters needed. The eight combination receptacles downstream handle mixed 15A and 20A plug types without outlet-type conflicts in a dense server rack.
- UL1778 + c-UL Listing: Dual-jurisdiction UL listing covers US and Canadian commercial facility AHJ requirements. If your data center or IDF closet requires permit sign-off, these are the certifications the inspector will ask for — not just a CE mark.
- 0–95% RH Operating Range: Full humidity tolerance without derating means this unit can be deployed in edge or industrial environments where precision climate control isn't guaranteed — warehouses, manufacturing floors, or remote telco/security closets running ambient HVAC only.
Deployment Considerations:
- Confirm PSI5-3000RT120 specifically before ordering — the MP2-130C physically will not mate with PSI5-2200RT120 (L5-20P output) or 1500VA PSI5 models. The Micropod family has seven variants across three input types; model-matching is not optional.
- The MP2-130C is a passive bypass switch — no SNMP, no outlet switching, no remote management. If you need per-outlet metering or remote reboot capability on the loads, that belongs at a managed PDU installed downstream of this unit, not here.
This unit is the right call for a PSI5-3000RT120 deployment in a commercial IDF or small data room where the maintenance SLA requires hot-swap UPS servicing without touching connected server or network loads — a realistic requirement for any facility running 24/7 operations with a single UPS per rack.
