APC by Schneider Electric SMX3000HV 3kVA Line-Interactive Rack/Tower UPS with Pure Sine Wave Output
Overview
The APC by Schneider Electric SMX3000HV is a 3kVA/2700W line-interactive uninterruptible power supply engineered for IT closets, network equipment rooms, and surveillance infrastructure that cannot tolerate power anomalies. With a pure sine wave output waveform, it satisfies the strict power requirements of active PFC power supplies found in modern servers, NVRs, and PoE switches — equipment that will fault or fail silently on the modified sine wave output common to entry-level UPS units. If you are protecting a surveillance head-end or structured cabling room, the SMX3000HV is the specification to match.
Key Features
- 3 kVA / 2700 W Output Capacity: At a 0.9 power factor, the SMX3000HV delivers 2700 W of real power — enough headroom to support a fully populated NVR chassis, a PoE switch stack, and ancillary networking gear simultaneously without running the UPS above 80% load, which is the safe operating ceiling for most commercial deployments.
- Pure Sine Wave Output: Active PFC server and network power supplies require a sine wave source or risk tripping overcurrent protection. This UPS produces a clean sine wave both on battery and on line, eliminating compatibility concerns with high-efficiency network hardware.
- Line-Interactive Topology with AVR: Automatic Voltage Regulation (AVR) corrects under- and over-voltage events across a 140 V to 280 V input window without switching to battery. In environments with chronic brownouts or utility overvoltage — common in older commercial buildings — AVR extends battery life significantly by absorbing sags and swells before they consume battery cycles.
- 140–280 V Wide Input Range: A 140-volt lower threshold handles deep brownouts that would drop most competitive units to battery, while the 280-volt upper ceiling accommodates high-line utility swings common in international and industrial sites. This range is especially relevant for installations in Latin American or Middle Eastern facilities sharing a 220/240 V distribution.
- 98.5% Efficiency: Operating at 98.5% efficiency in line mode means the SMX3000HV adds minimal heat load to the room and keeps energy costs low on a device that runs continuously, 24/7. Over a multi-year deployment lifecycle, that efficiency gap versus 92–95% competitive products translates to measurable cost savings on the utility bill.
- 645 J Surge Energy Rating: The integrated 645-joule surge suppressor absorbs transient spikes before they reach connected equipment — relevant for sites with frequent lightning exposure or shared circuits with HVAC and motor loads that inject transients onto the line.
- Emergency Power Off (EPO): The hardwired EPO port allows facilities management or a data center BMS to execute a controlled remote shutdown of all connected loads — a code requirement in many commercial machine rooms and a standard integration point for building automation systems.
- 10 ms Maximum Hold Time: During a transfer to battery, the SMX3000HV bridges the gap for up to 10 ms — well within the 20 ms tolerance spec of virtually all server and network power supplies. Equipment stays online through the transfer without reset or brownout-induced faults.
- 3:1 Crest Factor Tolerance: A 3:1 crest factor rating means the UPS can handle the high peak-to-RMS current demands of switch-mode power supplies without clipping or distortion, which matters when multiple SMPS loads switch simultaneously during a power-up sequence.
- 55 dB Noise Level: At 55 dB, this unit is designed for occupied spaces — server closets adjacent to open offices, or security operations rooms where staff are present. It won't add disruptive fan noise above ambient.
- 50/60 Hz Input and Output Frequency: Dual-frequency compatibility makes the SMX3000HV deployable across North American (60 Hz) and international (50 Hz) grid infrastructure without hardware modification.
Integration and Compatibility
The SMX3000HV is purpose-built for rack and tower UPS deployments protecting network video recorders, PoE switch stacks, and structured network closets. Its pure sine wave output and wide input voltage tolerance make it a compatible power foundation for virtually all commercial-grade active PFC power supplies. The EPO port integrates with building management systems and data center PDU infrastructure for coordinated emergency shutdown sequences. For installations requiring remote monitoring and management, the unit's communication interface supports network management card expansion, enabling SNMP-based monitoring and automated graceful shutdown of connected hosts. Pair with appropriate UPS accessories including replacement battery modules and management cards for a fully managed power protection stack. Consult the power and UPS category for complementary PDU and power distribution options.
Frequently Asked Questions
Q: Does the SMX3000HV produce a pure sine wave output on battery, or only on line power?
A: The SMX3000HV produces a pure sine wave output both when running on utility power and when operating on battery. This is critical for active PFC power supplies, which require a sine wave source to operate correctly and avoid nuisance tripping.
Q: What is the input voltage operating range of the SMX3000HV?
A: The SMX3000HV operates across an input voltage range of 140 V to 280 V. Automatic Voltage Regulation (AVR) corrects under- and over-voltage conditions within this window without transferring to battery power.
Q: Is the SMX3000HV suitable for both 50 Hz and 60 Hz grid environments?
A: Yes. The SMX3000HV supports both 50 Hz and 60 Hz input and output frequencies, making it compatible with North American and international utility infrastructure.
Q: What is the real power (watt) output of the SMX3000HV?
A: The SMX3000HV delivers 2700 W (3 kVA) of real output power at a 0.9 power factor, sufficient for powering fully loaded server or NVR infrastructure.
Q: Does the SMX3000HV include Emergency Power Off (EPO) capability?
A: Yes. The SMX3000HV includes a hardwired EPO port that allows remote shutdown of all connected loads — a standard requirement in commercial machine rooms and compatible with building automation and BMS integration.
Q: What is the efficiency rating of the SMX3000HV in normal line mode?
A: The SMX3000HV operates at 98.5% efficiency in line mode, minimizing heat generation and energy waste in 24/7 operational environments.
The SMX3000HV is one of the few line-interactive units in this power class that actually delivers 98.5% efficiency in line mode — that spec matters more than it sounds when the device runs 24/7 in a surveillance head-end or network closet. I recommend it specifically for deployments where the load mix includes active PFC power supplies, because the pure sine wave output eliminates the risk of PFC inrush faults that plague modified sine wave UPS installations.
Technical Highlights:
- 140–280 V AVR Window: The automatic voltage regulation range is exceptionally wide — 140 V lower bound absorbs deep brownouts without burning a battery cycle, and the 280 V upper ceiling handles the high-line conditions common on shared commercial distribution. In practice, this means the batteries last longer in grid-challenged environments.
- 645 J Surge Rating: At 645 joules, the integrated suppressor handles the transient environment of a typical commercial building — including HVAC motor starts and shared-circuit inductive loads. Not a substitute for a dedicated surge panel on high-exposure sites, but solid baseline protection for the UPS itself.
- 3:1 Crest Factor / 10 ms Hold Time: The 3:1 crest factor tolerance and 10 ms maximum transfer time are the two specs that determine whether network hardware actually rides through a transfer cleanly. Both are within the tolerance bands of all commercial server and switch power supplies I've tested.
Deployment Considerations:
- Output voltage range is 208–240 V — confirm your connected equipment accepts that range. This unit is not a 120 V output UPS; it targets international and 208 V commercial distribution, not standard North American 120 V branch circuits.
- Hold time of 2–10 ms is the transfer gap, not the runtime. Runtime depends on connected load and battery configuration — do not confuse these two specs when sizing for outage duration.
Deploy the SMX3000HV in a 208 V or 240 V commercial machine room protecting a surveillance NVR stack, managed PoE switch infrastructure, or a structured cabling head-end where active PFC loads and 24/7 uptime requirements rule out lower-efficiency or modified sine wave alternatives.
