APC by Schneider Electric SMT3000RMI2UC Smart-UPS 3000VA LCD RM 2U 230V with SmartConnect
Overview
The APC by Schneider Electric SMT3000RMI2UC is a 3000VA / 2700W line-interactive rack-mount UPS in a 2U form factor, designed for 230V environments where clean, conditioned power is non-negotiable. Whether you're protecting an NVR stack, a PoE switch infrastructure, or a converged IT/physical-security rack, the SMT3000RMI2UC delivers true sine wave output, automatic voltage regulation across a 151–302V input range, and SmartConnect cloud management — without requiring a dedicated power shelf or a 3U cutout. For security integrators and IT architects specifying rack power in a single chassis, this is a well-understood platform with a long deployment history in commercial environments.
Key Features
- 3000VA / 2700W Line-Interactive Topology: Line-interactive design conditions incoming power continuously — not just during an outage. Brownouts, sags, and overvoltages between 151V and 302V are corrected by AVR without switching to battery, which extends battery life significantly on sites with marginal utility power. The 2700W real-power rating means you can load it near nameplate without derating concerns on most rack deployments.
- True Sine Wave Output: Active PFC power supplies — standard in modern servers, NVRs, and managed switches — require a true sine wave UPS to operate correctly during transfer. Modified-wave units cause audible buzzing, higher heat, and premature PSU failure on PFC loads. The SMT3000RMI2UC outputs a clean sine waveform regardless of whether it's on utility or battery, so your equipment never knows the difference.
- 151–302V Input Voltage Window: A 151V low-end threshold means the UPS stays on utility power through deep brownouts rather than unnecessarily cycling the battery. On sites with poor grid quality — older commercial buildings, industrial facilities, areas with frequent voltage sag — this wide window directly translates to longer battery service life.
- 98.9% Efficiency: At 98.9% efficiency, the SMT3000RMI2UC wastes less than 1.1% of input power as heat. Over a year of 24/7 operation at half load (~1350W), that efficiency delta versus a 95% unit saves roughly 380 kWh — meaningful on any energy-metered rack or colocation deployment where power draw is billed.
- SmartConnect Cloud Management: SmartConnect provides remote UPS monitoring, firmware updates, and event notification via a cloud portal without requiring a local network card or NMC accessory on basic deployments. For security integrators managing distributed sites, this reduces truck rolls for routine UPS health checks.
- C13 and C19 Output Outlets: The SMT3000RMI2UC provides both C13 and C19 outlet types, accommodating standard IEC C14-inlet devices (switches, NVRs, smaller servers) as well as C20-inlet high-draw equipment (dense PoE switches, larger servers) from a single UPS without adapters.
- Automatic Voltage Regulation (AVR): The built-in AVR corrects both high and low voltage conditions in real time — no battery involvement required. On surveillance deployments where NVRs run continuous write cycles, avoiding unnecessary battery transfers reduces wear on both the battery and connected storage.
- 320J Surge Energy Rating: 320 joules of surge suppression handles common transients from switching loads and nearby equipment. While this is not a substitute for a dedicated surge suppression panel on lightning-prone sites, it provides a baseline layer of protection integrated directly into the power path.
- Auto-Restart and Audible Alarms: Auto-restart brings the UPS and connected load back online automatically after a utility restoration — critical for unmanned security installations where manual intervention after a power event isn't practical. Audible alarms provide on-site indication of fault conditions without relying solely on network connectivity.
- 2U Rack Form Factor: The 2U chassis fits standard 19-inch racks and leaves minimal rack space consumed. On a 12U or 16U edge security rack, 2U for UPS is an acceptable overhead without sacrificing space for additional switches or compute.
Integration and Compatibility
The SMT3000RMI2UC operates on 230V / 50–60Hz input, making it suited for European, Middle Eastern, Asian-Pacific, and other non-North-American 230V infrastructures. Output is regulated between 220V and 240V, covering the full tolerance band expected by IEC-compliant equipment. The C13/C19 outlet mix integrates cleanly with standard data-center and security rack cabling. SmartConnect management is handled via the included interface; for deeper SNMP or BACnet integration, verify NMC card compatibility against APC's current accessory lineup for this chassis generation. The UPS operates at a noise level of 55 dB — audible in a quiet office environment but within normal expectations for a 3kVA unit in a dedicated IDF or server room.
Frequently Asked Questions
Q: What is the difference between the SMT3000RMI2UC and a standard offline UPS for rack applications?
A: The SMT3000RMI2UC uses a line-interactive topology, meaning it actively regulates voltage (between 151V and 302V input) without switching to battery for every fluctuation. An offline UPS only switches to battery when utility power falls out of range entirely, resulting in more battery cycling and no voltage correction during brownouts. For equipment with active PFC power supplies — which is most modern networking and server hardware — the true sine wave output of the SMT3000RMI2UC is also a requirement that offline units typically cannot meet.
Q: Does the SMT3000RMI2UC support 230V environments outside of North America?
A: Yes. The SMT3000RMI2UC is specifically designed for 230V / 50–60Hz input, with regulated output between 220V and 240V. It is suitable for European, Middle Eastern, and Asia-Pacific deployments using IEC outlet standards. Verify local outlet type requirements, as the C13/C19 outputs are IEC-standard and compatible with most international rack equipment.
Q: Can the SMT3000RMI2UC power active PFC power supplies without issues?
A: Yes. The SMT3000RMI2UC outputs a true sine wave on both utility and battery, which is required for correct operation of active PFC power supplies. Modified-wave UPS units can cause instability, noise, or PSU shutdowns on PFC loads. This UPS avoids that problem entirely.
Q: What does SmartConnect provide, and is a separate network card required?
A: SmartConnect provides cloud-based remote monitoring, event notification, and firmware management for the UPS without requiring a separate network management card (NMC) for basic monitoring functions. It connects via an existing network port on the UPS. For full SNMP/network integration into NMS platforms, a dedicated NMC accessory may be required — confirm compatibility with APC's current NMC lineup for this chassis.
Q: How wide is the input voltage window, and why does it matter for sites with poor power quality?
A: The SMT3000RMI2UC accepts input from 151V to 302V and uses AVR to correct voltage continuously without battery involvement. On sites with frequent brownouts or overvoltages — common in older commercial buildings or industrial facilities — this wide window keeps the UPS on utility power rather than running the battery unnecessarily, directly extending battery service life.
Q: What is the hold time for the SMT3000RMI2UC during a power interruption?
A: The specified hold time is 4ms minimum to 8ms maximum at full load — this is the transfer time from utility to battery. For most IT and security equipment, this transition is within the hold-up time of the connected power supplies, meaning no interruption to connected devices during the switchover.
The SMT3000RMI2UC sits in a specific sweet spot I see regularly on mid-size commercial security and IT rack deployments: 2700W of real power, 2U height, and a 151–302V input window wide enough that you're not constantly burning battery capacity on sites where utility quality is marginal. The 98.9% efficiency figure isn't marketing — at a half-load draw of roughly 1350W, you're dissipating under 15W as heat, which matters in a sealed IDF closet where every watt of heat generation has to be managed.
Technical Highlights:
- True Sine Wave Output: With essentially all modern NVRs, managed PoE switches, and edge servers running active PFC PSUs, a modified-wave UPS is a reliability liability. The SMT3000RMI2UC's sine output means zero compatibility concerns with PFC loads — no buzzing, no thermal stress, no unexpected shutdowns on battery.
- AVR Window 151–302V: This is one of the wider AVR windows in the 3kVA class. On a site where utility regularly sags to 160–170V during peak load — a real scenario in older commercial and light-industrial buildings — the UPS self-corrects without battery involvement, which directly protects battery longevity over a multi-year deployment lifecycle.
- 4–8ms Transfer Time: At 4ms minimum transfer, the gap between utility loss and battery output is well within the hold-up time of any standard ATX or IEC PSU. Connected devices experience zero interruption in practice, which is the fundamental requirement for continuous-recording surveillance infrastructure.
Deployment Considerations:
- The 55 dB noise rating is within normal range for a 3kVA unit, but place this in a dedicated equipment room or IDF rather than an open office or reception area — it will be audible under load.
- SmartConnect handles basic remote monitoring without an NMC card, but if you're integrating with an existing SNMP-based NMS or BMS platform, budget for a compatible network management card — the base unit's SmartConnect interface is cloud-portal-only and may not expose the SNMP MIB your monitoring stack expects.
The SMT3000RMI2UC is a strong fit for a 2U slot in a 230V security-focused rack — specifically the scenario where you're protecting an NVR, a core PoE switch, and an access control panel simultaneously and need guaranteed sine wave output with active voltage regulation rather than a basic standby unit.
