APC by Schneider Electric SMX3000HVNC Smart-UPS 3000VA Line-Interactive Rack/Tower UPS
The SMX3000HVNC is APC's 3000VA (2700W) line-interactive uninterruptible power supply from the Smart-UPS X series, designed for server rooms, network closets, and security head-end equipment where maintaining clean, conditioned power during brownouts and outages is non-negotiable. It operates at 230V output and accepts a wide input voltage range of 140–280V, making it suitable for the voltage variability found in international facilities and older commercial buildings. It ships in a form factor that converts between 4U rack-mount and freestanding tower without additional hardware — useful when rack space is at a premium and a floor-standing option is the fallback.
Overview
Line-interactive topology sits between basic standby UPS units and true online double-conversion. The SMX3000HVNC corrects voltage sags and surges using its automatic voltage regulation (AVR) without switching to battery — extending battery life significantly in environments where input voltage fluctuates regularly but doesn't fully drop out. When the input falls outside the 140–280V window or fails entirely, the unit transfers to battery-backed inverter output. At 2700W of real power capacity, it can sustain a meaningful load: a dense 1U server, a PoE switch stack, or a cluster of IP cameras and NVR hardware. For network video recorders and supporting infrastructure, runtime calculations should factor actual connected load against battery capacity.
Key Features
- 3000VA / 2700W Capacity: The 0.9 power factor means nearly all rated VA translates to usable watts — important when sizing against modern server PSUs and PoE switch loads that are predominantly resistive. Undersizing a UPS is one of the most common rack room mistakes; at 2700W you have meaningful headroom for a mixed security head-end.
- Wide Input Range 140–280V: A 140V lower threshold is unusually tolerant — most competing units switch to battery at 160V or higher. In facilities with chronic undervoltage or on generator power where voltage regulation is loose, this range keeps the unit on utility power longer and preserves battery cycles for genuine outages.
- 47–63 Hz Input Frequency Acceptance: Covers both 50 Hz and 60 Hz grid infrastructure, and tolerates generator frequency drift at the edges. If your backup generator doesn't regulate tightly to 50 Hz, the SMX3000HVNC won't false-trip into battery mode.
- 4U Rack / Tower Convertible Form Factor: Ships with hardware to mount in a standard 19-inch rack at 4U or stand vertically as a tower. Facilities that deploy in phases — starting with a rack, later moving to a dedicated UPS room — don't need a different SKU. Dimensions are 7.00" H × 17.00" W × 19.00" D in rack orientation.
- Smart-Slot Interface: The Smart-Slot expansion bay accepts optional network management cards, relay interface cards, or environmental monitoring modules. Adding a network card converts this UPS into a remotely managed device — enabling SNMP monitoring, scheduled shutdowns, and integration with data center infrastructure management (DCIM) platforms without replacing the unit.
- User-Replaceable Batteries (APCRBC143): The SMX3000HVNC uses the APCRBC143 battery cartridge, which can be hot-swapped without powering down connected equipment. For 24/7 security and surveillance infrastructure, this matters — planned battery replacement on a 3–5 year cycle doesn't require a maintenance window.
- Multiple Input Connection Options: Accepts British BS1363A, IEC-320 C20, and Schuko CEE 7/EU1-16P input connectors — covering the standard European, UK, and international rack power distribution configurations without an adapter.
- 230V / 50–60 Hz Output: Regulated 230V AC output with ±3 Hz frequency tolerance on inverter. Connected equipment sees stable voltage regardless of input condition, which matters for sensitive electronics like network switches and IP camera power supplies that can be damaged by sustained undervoltage.
Integration & Compatibility
The SMX3000HVNC integrates into managed power infrastructure via its Smart-Slot — pair it with an APC network management card (sold separately) to expose the unit to SNMP-based monitoring tools, NMSes, or building management systems. The Smart-UPS X series is broadly compatible with APC PowerChute software for graceful OS shutdown sequencing during extended outages. For IP camera deployments and associated PoE switch infrastructure, the UPS sits upstream of the distribution layer — size your PoE switch draw plus NVR load against the 2700W capacity to confirm runtime at your actual load percentage. The APCRBC143 replacement battery is a stocked APC part, keeping the replacement supply chain straightforward. If you're planning a larger PoE switch deployment or multi-NVR head-end, a higher-capacity Smart-UPS variant in the same family may be warranted — the SMX3000HVNC is well-matched to mid-density racks but reaches its ceiling with fully loaded enterprise chassis.
Frequently Asked Questions
Q: What is the difference between the SMX3000HVNC and a standard online double-conversion UPS?
A: The SMX3000HVNC uses line-interactive topology with automatic voltage regulation. It corrects voltage sags and surges without switching to battery, which extends battery life. An online double-conversion UPS runs connected equipment continuously off the inverter regardless of input quality — offering zero transfer time and tighter output regulation, but at higher cost and with more battery wear. For most server and security head-end applications, line-interactive is the practical choice; double-conversion is typically reserved for tier-3/4 data center environments or extremely sensitive loads.
Q: Can the SMX3000HVNC be rack-mounted, and what rack space does it require?
A: Yes. The SMX3000HVNC is a 4U rack-mountable unit and also supports freestanding tower orientation. It measures 7.00" H × 17.00" W × 19.00" D, fitting a standard 19-inch equipment rack at 4U.
Q: What input connections does the SMX3000HVNC accept?
A: The unit accepts British BS1363A, IEC-320 C20, and Schuko CEE 7/EU1-16P input connectors, covering standard UK, international rack (C20), and European Schuko power distribution configurations.
Q: How do I expand the SMX3000HVNC with network management?
A: The unit includes a Smart-Slot expansion bay. Inserting an optional APC network management card (sold separately) adds SNMP monitoring, remote shutdown scheduling, and DCIM integration. Without a card installed, local management is available via the front panel.
Q: What replacement battery does the SMX3000HVNC use, and can it be replaced without downtime?
A: The SMX3000HVNC uses the APCRBC143 battery cartridge. The cartridge is designed for hot-swap replacement — connected equipment remains powered during the swap, which is critical for 24/7 surveillance and security infrastructure.
Q: Is the SMX3000HVNC suitable for use outside the UK and Europe?
A: The SMX3000HVNC is rated for 208V and 230V input and is identified as an international version. Its wide input range (140–280V) and multi-connector input support accommodate varied international power infrastructure. Confirm local voltage and connector standards before deployment; output is fixed at 230V AC.
The SMX3000HVNC is a unit I'd reach for when specifying power protection for a 230V international security head-end — specifically because that 140–280V input window buys real operational resilience on generator-backed or older building power where most line-interactive units would be cycling to battery constantly.
Technical Highlights:
- 2700W Real Power at 0.9 PF: Modern rack equipment — PoE switches, NVRs, managed servers — presents near-unity power factor loads. The SMX3000HVNC's 2700W capacity at 0.9 PF means what's on the nameplate is what you can actually load, not a theoretical VA number that shrinks when you do the math.
- 140–280V Input Range: Most line-interactive units in this class switch to battery at 160V minimum. The extra 20V of low-end tolerance on the SMX3000HVNC directly reduces unnecessary battery discharge events in facilities with weak utility feeds — and that translates to longer battery service intervals before the APCRBC143 needs replacement.
- Smart-Slot Expansion: The onboard Smart-Slot is what separates this from a dumb UPS. Drop in an APC AP9630 or AP9631 network card and the unit joins your NMS via SNMP — you get runtime telemetry, input/output voltage logging, and scripted graceful shutdown. For an unmanned comms room, that visibility is the difference between a managed outage and an unplanned one.
Deployment Considerations:
- Output is fixed at 230V AC — verify all connected equipment is rated for 230V before deployment. The SMX3000HVNC is not a step-down transformer; it will not convert 230V output to 120V for mixed-voltage loads.
- The 4U rack footprint is deeper than it looks on paper at 19 inches — confirm your rack has adequate rear clearance, particularly in shallow-depth wall-mount enclosures common in smaller security installations.
This unit is a well-matched choice for a mid-density 230V security rack — a 24-port PoE switch stack, a dual-NVR head-end, and a managed network layer fit comfortably within 2700W, and the Smart-Slot gives you the remote management visibility that enterprise and multi-site deployments require.
