APC by Schneider Electric SU2000R3X155 2000VA Ruggedized Rack-Mount UPS
Overview
The SU2000R3X155 is APC's ruggedized variant of the Smart-UPS 2000VA line — a 2000VA / 1600W rack-mount unit built for environments where standard commercial UPS hardware isn't rated to survive. At 3U, it slots into a standard 19-inch rack and delivers 120V output with both USB and RS-232 management ports, giving integrators flexibility in how they connect it to a network management card or host system. If you're powering surveillance NVRs, access control servers, or network infrastructure in a hardened rack, this is the model to consider rather than the standard SU2000R3.
The unit weighs 80 lbs — plan your rack positioning accordingly and confirm your rack's weight capacity before ordering. Lead-acid battery chemistry means eventual battery replacement is a known maintenance event, not a surprise.
Key Features
- 2000VA / 1600W Power Capacity: Enough headroom to carry a mid-density NVR, a managed PoE switch, and ancillary network gear simultaneously — without running the UPS near its thermal limit. Size your actual load to 70–80% of rated capacity for runtime headroom.
- Ruggedized Construction: The -RUGGEDIZED designation targets deployments where vibration, shock, or harsh rack environments would stress standard UPS hardware — think mobile command, transit, or industrial surveillance racks. This is the differentiating spec versus the base SU2000R3.
- 3U Rack Form Factor: Fits standard 19-inch EIA racks. Three rack units is a meaningful footprint in a dense deployment — verify available rack space before ordering, especially in pre-configured surveillance rack systems.
- 120V Input and Output: Designed for North American single-phase infrastructure. Both input and output are 120V, so no step-up or step-down transformer is needed in a standard US installation.
- USB and RS-232 Management Ports: Two distinct communication paths — RS-232 for legacy SNMP or NMC integration, USB for direct host connection. Lets you wire management into nearly any NVR, server, or network device without an adapter.
- Lead-Acid Battery: A proven chemistry for this power class. Replacement batteries are widely available and field-swappable, which matters for long-cycle surveillance deployments where the UPS may outlive multiple battery generations.
Integration and Compatibility
The SU2000R3X155 fits standard surveillance power rack deployments and works alongside network video recorders and managed switches. The RS-232 and USB ports support APC's PowerChute software for graceful shutdown coordination — critical for NVRs writing to disk when power events occur. For PoE switch protection, confirm total switch draw stays well within the 1600W real-power ceiling. If you're speccing a full rack, review the APC by Schneider Electric power lineup for complementary PDUs and extended battery modules.
Frequently Asked Questions
Q: What is the real-power output of the SU2000R3X155?
A: The SU2000R3X155 delivers 1600W of real power at a 2000VA apparent power rating. Size your connected load to no more than 1,280W (80% of 1600W) for reliable runtime and thermal headroom.
Q: What does the ruggedized designation mean for this model?
A: The ruggedized variant is engineered for environments with elevated vibration, shock, or temperature stress — such as mobile command vehicles, transit installations, or hardened industrial racks — where a standard Smart-UPS would be at risk.
Q: What management interfaces does the SU2000R3X155 include?
A: It includes both a USB port and an RS-232 serial port for host and network management connectivity. These support APC PowerChute software for graceful shutdown and power event monitoring.
Q: How much does the SU2000R3X155 weigh, and does that affect rack placement?
A: The unit weighs 80 lbs. Verify your rack's rated weight capacity and plan for bottom-of-rack placement to keep the center of gravity low in mobile or freestanding rack enclosures.
Q: What battery type does the SU2000R3X155 use?
A: It uses a sealed lead-acid battery. Replacement batteries are available through APC's standard RBC replacement battery cartridge program, making field servicing straightforward over the unit's service life.
The SU2000R3X155 stands out from the standard Smart-UPS 2000 lineup specifically because of its ruggedized rating — that's the reason to spec it over the base model, and it's the first question I ask when a customer asks about this unit. If the rack is going into a fixed, climate-controlled server room, the standard variant is fine and likely less expensive. If the rack is mobile, vehicle-mounted, or in an industrial bay, the SU2000R3X155 is the correct call.
Technical Highlights:
- 1600W Real Power: At 2000VA with an 0.8 power factor, you get 1600W of usable capacity — enough to run a 16-channel NVR, a 24-port PoE switch, and a firewall with margin remaining. Keep actual load under 1,280W for runtime buffer.
- Dual Management Ports (USB + RS-232): Having both interfaces on the same unit means you're not forced into a single integration path. RS-232 is still the right choice for legacy NMC cards; USB pairs cleanly with modern servers running PowerChute Network Shutdown.
- 80 lb Lead-Acid Platform: The weight is a real installation constraint — bottom-rack mounting is mandatory in mobile deployments to prevent tip hazards. Lead-acid also means battery replacement is a scheduled maintenance item, typically every 3–5 years depending on operating temperature.
Deployment Considerations:
- Confirm rack weight rating before installation — 80 lbs for the UPS alone, plus NVR, switch, and cabling weight can push lighter open-frame racks past their rated load.
- The 120V single-phase input means this unit is North America-specific; do not attempt to deploy on 208V or 240V circuits without a transformer — the SU2000R3X155 is not a universal-input model.
This unit is the right pick for mobile surveillance command racks, hardened industrial monitoring stations, and transit security deployments where vibration tolerance and reliable 1600W runtime protection are non-negotiable requirements.
