CyberPower CPS1500AVR Rack-Mount UPS with Automatic Voltage Regulation
The CyberPower CPS1500AVR is a 1500VA/900W line-interactive UPS designed for surveillance system servers, network appliances, and departmental workstations where stable power and battery backup are non-negotiable. This model combines automatic voltage regulation (AVR) with eight surge-protected outlets and simulated sine wave output to keep your recording infrastructure running through brownouts, sags, and brief outages.
Overview
The CPS1500AVR delivers 1500VA of capacity with 900W of continuous power output — enough to support a mid-sized NVR cluster, managed switches, and peripheral equipment simultaneously. Its line-interactive topology means it actively regulates voltage fluctuations between 90–140 VAC without draining the battery, extending battery life on marginal grid conditions. The unit is certified to UL1778, cUL, and FCC Part 15 Class B standards, making it suitable for commercial and industrial surveillance deployments.
Key Features
- Automatic Voltage Regulation (AVR): Maintains 120 VAC ± 10% output across a 90–140 VAC input range without triggering battery drain — critical in areas with frequent voltage sags or spikes that would otherwise shorten UPS battery life or cause nuisance shutdowns on sensitive network gear.
- Eight NEMA 5-15R Outlets: All eight outlets provide both surge protection and battery backup, so you can branch multiple devices (NVR, PoE switches, managed hubs) without external surge strips. No outlet hierarchy means simpler load distribution and fewer failed branches during an outage.
- Sealed Lead-Acid Battery (28Ah Total): Four 12V 7Ah cells in series deliver 18 minutes of runtime at 50% load or 7 minutes at full 900W — sufficient for a graceful NVR shutdown sequence or a brief power restoration wait in most utility interruptions. Hot-swappable design means battery replacement doesn't require UPS downtime.
- Simulated Sine Wave Output: Unlike square-wave UPS designs, simulated sine wave output prevents transformer hum and reduces audible noise on audio equipment or switched-mode power supplies — an advantage if your surveillance cabinet is near office space or within earshot of passive monitoring.
- Data Line Protection (Ethernet, Tel, Coax): Integrated data line surge suppression protects RJ-45, phone, and coax inputs, preventing lightning-induced surges from riding into your network infrastructure or analog camera lines.
- Connected Equipment Guarantee: $300,000 Connected Equipment Coverage protects downstream devices against damage caused by power anomalies — meaningful liability offset if a surge event damages an NVR, switch, or camera PoE injector after passing through the UPS.
Integration and Compatibility
The CPS1500AVR integrates with surveillance and IT infrastructure via USB, Serial, and SNMP interfaces. USB connectivity supports PowerPanel Business Software for remote shutdown signaling, battery status monitoring, and automated graceful NVR shutdown when grid power is lost. SNMP integration allows rack-level monitoring in larger deployments where multiple UPS units feed different branches (NVR tier, PoE switch tier, network appliance tier). Serial and USB can also trigger third-party VMS or access control systems to initiate automated shutdown routines — check your VMS vendor's power management module for pre-built drivers or Modbus support.
The 3-Year Limited Warranty covers internal components, battery, and labor. Operating temperature range of 32–104°F (0–40°C) suits most server closets and climate-controlled cabinets; avoid outdoor or unheated enclosures where ambient cold would reduce battery capacity.

Frequently Asked Questions
Q: How long will the CPS1500AVR keep my NVR and PoE switch running if grid power fails?
A: At 50% load (typical for an NVR plus a managed PoE switch), expect 18 minutes of battery runtime. At full 900W draw, that drops to 7 minutes. Most modern NVRs can perform a clean shutdown in 2–3 minutes, so 7 minutes at full load is usually adequate for a controlled shutdown sequence. For longer runtime, consider a higher-capacity model in the CyberPower lineup.
Q: Does the CPS1500AVR require a separate surge strip for my equipment, or are all outlets protected?
A: All eight NEMA 5-15R outlets provide both surge protection and battery backup. No separate surge strip is needed — plug devices directly into the UPS.
Q: Can I monitor the CPS1500AVR remotely or integrate it with my VMS?
A: Yes. The unit includes USB, Serial, and SNMP connectivity. PowerPanel Business Software enables remote monitoring and automated shutdown signals. SNMP support allows integration into enterprise monitoring systems, and Serial/USB can interface with VMS power management modules — check your VMS vendor's documentation for driver availability.
Q: What's the warranty on the CPS1500AVR?
A: 3-Year Limited Warranty covers internal components, battery, and labor. Additionally, the unit carries $300,000 Connected Equipment Coverage for downstream devices.
Q: Will the AVR feature prevent the battery from draining on marginal grid power?
A: Yes. Automatic Voltage Regulation actively corrects sags and spikes between 90–140 VAC input without triggering the inverter, so the battery remains in standby. This extends battery lifespan and avoids nuisance shutdowns in areas with chronic sag conditions.
Q: Is the CPS1500AVR rack-mountable only, or can it sit on a shelf?
A: The CPS1500AVR supports both rack mounting (1U) and tower placement. Dimensions are 17.25 x 3.5 x 15.75 inches. Verify rack space and depth clearance (15.75 inches) before installation.
I've deployed the CPS1500AVR in mixed server environments where grid stability is marginal — the AVR topology makes a real difference. Most integrators forget that a UPS burning battery on every voltage sag will exhaust its cells in 2–3 years instead of 5. The CPS1500AVR's automatic regulation means the battery stays in reserve, so when an actual outage hits, you get the full 18 minutes at half load to execute a controlled shutdown.
Technical Highlights:
- Automatic Voltage Regulation (AVR): Actively corrects sags and spikes between 90–140 VAC without inverter drain. In environments with frequent 10–15% sag events (not uncommon in older commercial buildings or areas fed by aging distribution), this keeps the battery in standby and extends cell lifespan significantly.
- 1500VA / 900W Capacity: Handles a typical mid-tier NVR (200–300W), a 24-port PoE switch (150–200W at full load), and a managed ethernet switch (50–100W) with headroom for network appliances. You're not cutting margins on a 900W draw estimate.
- Hot-Swappable Battery (4 x 12V 7Ah): 28Ah total capacity means 18 minutes at half load or 7 minutes at full draw. Battery replacement on a live system is straightforward — no UPS downtime, which matters in 24/7 surveillance shops.
Deployment Considerations:
- Seven-minute runtime at full 900W load is tight if your NVR cluster runs at peak draw during a sustained power event. Measure your actual power draw under peak recording and verify margin against the 900W spec; some larger 16- or 32-channel NVRs creep closer to that ceiling than you'd think.
- The simulated sine wave output is clean for most network and surveillance equipment, but if you're running older legacy switching supplies or analog video distribution equipment with inductive loads, verify compatibility with your device datasheets — a few older appliances still prefer true sine output.
This unit fits well in surveillance server rooms with marginal grid stability and regular brownout conditions — integrators consistently report five-year battery lifespan in AVR-enabled deployments versus two to three years on non-regulating UPS designs. Not a replacement for site-level power conditioning, but a solid tactical win for preventing nuisance shutdowns and extending your UPS battery economics.
