APC by Schneider Electric SURTD3000XLIM Smart-UPS RT 3000VA 230V Marine Rack UPS
Overview
The APC Smart-UPS RT SURTD3000XLIM is a 3000VA / 2100-watt online double-conversion UPS engineered for marine and maritime environments where shore power is unreliable, voltage is dirty, and equipment failure is not an option. Running on 230V input and output, this 3U rack-mount unit is purpose-built for vessel bridge systems, shipboard server rooms, security equipment racks, and offshore industrial controls that demand true online UPS topology — not standby or line-interactive.
Unlike standard commercial UPS units, the SURTD3000XLIM carries a marine designation, which signals suitability for the vibration, humidity, and power-quality extremes found at sea. If you are specifying power protection for a land-based data center or standard commercial rack, a conventional Smart-UPS RT variant will serve better. This model is the correct choice when the installation environment itself is the challenge.
Key Features
- 3000VA / 2100W Capacity: Sufficient headroom to carry a populated 3U security NVR, a PoE switch stack, and several network appliances simultaneously — without running the UPS above 70% load, which is the operational threshold that preserves battery runtime and longevity in demanding environments.
- 230V Input and Output: Matches European and international single-phase power standards (IEC 60320 C20 inlet, BS1363A British, and Schuko CEE 7/EU1-16P connection types included) — no step-up or step-down transformer needed for international vessel deployments.
- 3U Rack Form Factor: Occupies three rack units, fitting neatly into a standard 19-inch equipment rack. At 17.01 in. tall, 25.98 in. deep, and 5.12 in. wide, measure your rack depth carefully — 26 inches of depth is not universal, and shallow-depth wall-mount enclosures will not accommodate this unit.
- Eight IEC 60320 Outlets Plus Two IEC Jumper Connections: The outlet block provides eight standard C13/C14-style IEC 60320 receptacles for direct device connections, plus two IEC jumper ports for daisy-chaining or extended battery module (XL) integration — giving you flexibility to scale runtime without replacing the main unit.
- Front-Mounting Configuration: Designed for front-access installation, which matters on vessels where rear rack access may be physically restricted by bulkhead placement or tight equipment bay layouts.
- Lead-Acid Battery Chemistry: Valve-regulated lead-acid (VRLA) batteries are the correct choice for marine environments — they handle temperature excursions better than lithium alternatives in uncontrolled below-deck spaces and are widely serviceable internationally, which matters when a battery swap is needed in a port far from home.
- 8 ft (2.44 m) Input Cord: The included 8-foot cord provides enough reach for most rack-to-PDU or rack-to-shore-power connections without requiring an extension — a detail that matters during tight equipment bay installations where pulling additional cabling adds labor.
- RJ-45 Serial Interface Port: Provides direct UPS management and monitoring connectivity. Pair this with APC's management software or an AP9630/AP9631 network management card (sold separately) to enable remote monitoring of load, battery state, and runtime — essential for unmanned equipment rooms on vessels.
Integration and Compatibility
The SURTD3000XLIM integrates into APC by Schneider Electric's Smart-UPS RT ecosystem, meaning it accepts APC XL extended battery modules via the IEC jumper connections for sites where runtime extension beyond the internal battery is required. The RJ-45 serial port supports APC's PowerChute software for graceful shutdown management on connected servers. For rack UPS deployments in security operations centers or maritime command rooms, integration with a network management card enables SNMP-based monitoring within existing NMS platforms — consult your power protection planning guide for card compatibility with the SURT chassis family. The unit's output connector set (IEC 60320, BS1363A, Schuko) makes it compatible with the full range of international rack-mount equipment commonly found in mixed-vendor security and networking deployments. For installations also requiring PoE switch protection, verify your switch's total PoE draw plus compute load stays below the 2100W output ceiling under all operating conditions.
Frequently Asked Questions
Q: What does the marine designation on the SURTD3000XLIM mean in practice?
A: The marine designation indicates this unit is engineered to withstand the environmental stresses typical of vessel installations — including vibration, humidity, and wider power-quality variation from shore power or onboard generators. It is not a standard commercial UPS variant and is the appropriate choice when the physical installation environment is a marine or offshore setting.
Q: Can the SURTD3000XLIM accept extended battery modules for longer runtime?
A: Yes. The two IEC jumper connections on the outlet block are designed to interface with APC XL external battery modules, allowing runtime extension without replacing the base unit. This is one of the defining features of the Smart-UPS RT XL architecture.
Q: What input and output voltages does the SURTD3000XLIM support?
A: The SURTD3000XLIM operates on 230V input and delivers 230V output. It is not a dual-voltage or auto-sensing unit — confirm your shore power or generator output is 230V single-phase before specifying this model.
Q: How deep is the SURTD3000XLIM, and will it fit a standard two-post rack?
A: The unit is 25.98 inches deep. Two-post open-frame racks typically accommodate this depth, but shallow-depth wall-mount enclosures (under 24 inches usable depth) will not. Measure your rack's usable interior depth against 25.98 inches before ordering.
Q: What management interface does the SURTD3000XLIM include?
A: The unit includes an RJ-45 serial interface port. For network-based SNMP monitoring and remote management, an APC network management card (such as the AP9630 or AP9631, sold separately) must be installed in the UPS's expansion slot.
Q: What outlet types are available on the SURTD3000XLIM?
A: The outlet block includes eight IEC 60320 receptacles and two IEC jumper connections. Input connection types include BS1363A British, IEC 60320 C20, and Schuko CEE 7/EU1-16P, covering the primary international single-phase standards.
The SURTD3000XLIM is one of the few UPS models I'd specify without hesitation for a shipboard security rack — the marine designation isn't marketing language, it represents a real engineering decision to build for environments where a standard commercial UPS would degrade faster than you can schedule a service call. The 3000VA / 2100W capacity and 230V I/O make it the right size for a fully loaded security and networking bay on a mid-sized commercial vessel.
Technical Highlights:
- 3000VA / 2100W Output: Enough capacity to protect a security NVR, managed PoE switch, and network appliances simultaneously — keeping load below 70% is achievable in most vessel equipment bay configurations, which is where you want to operate for battery health.
- IEC Jumper Connections: The two IEC jumper ports aren't just pass-through outlets — they're the interface point for APC XL external battery modules. In a maritime deployment where runtime during port power transitions can be critical, the ability to bolt on additional battery capacity without replacing the UPS chassis is a real operational advantage.
- Front-Access Mounting: The front-mounting configuration directly addresses vessel rack installations where bulkheads or equipment bay enclosures prevent rear access — a spec that gets ignored in terrestrial deployments but becomes a hard constraint at sea.
Deployment Considerations:
- Confirm available rack depth before ordering — at 25.98 inches deep, this unit requires a rack with at least 26 inches of usable interior depth; many wall-mount enclosures used in smaller vessel installations fall short of this.
- The RJ-45 serial port provides local management only out of the box; if your vessel operations center requires remote SNMP monitoring, budget for an APC network management card installed in the expansion slot — the base unit does not provide network-accessible monitoring without it.
Best deployment fit: a 3U security equipment rack on a commercial or government vessel running 230V shore power or generator, where the installation requires proven marine-rated power protection with a clear path to runtime extension via APC XL battery modules and integration into a centralized power monitoring system.
