APC by Schneider Electric BE700G3 700VA Standby UPS Battery Backup
Overview
The APC by Schneider Electric BE700G3 is a 700VA/420W standby UPS designed to protect workstations, network equipment, and small surveillance systems from power outages, voltage fluctuations, and surges. At its core, this is an offline (standby) topology unit — it sits idle on utility power and switches to battery when an outage or sag is detected, making it a cost-effective choice for environments where brief transfer delays are acceptable and clean sine wave output is not a hard requirement. If your deployment involves sensitive variable-speed motor loads or certain enterprise-class servers that specify pure sine wave input, look at APC's line-interactive or online double-conversion models instead. For network video recorders, PoE switches, and workstation-class edge servers in surveillance closets, the BE700G3 hits the right balance of capacity and price.
Key Features
- 700VA / 420W Capacity: At 420W of real power output, this unit can sustain a mid-range NVR plus a small managed switch through a typical short outage — enough time for a clean shutdown or generator handoff. Size your load to 80% or less (around 336W) to avoid stressing the battery and shortening its service life.
- Standby (Offline) Topology: The BE700G3 draws directly from utility power under normal conditions, switching to battery only on failure. Transfer happens in approximately 10 ms — fast enough for most computing equipment, which tolerates gaps up to 20 ms without issue, but not fast enough for some industrial PLCs or medical-grade hardware with tighter hold-up requirements.
- Pseudo Sine Wave Output: During battery operation, the BE700G3 produces a stepped approximation of a sine wave rather than a true sine. This is adequate for most switching power supplies used in computers, NVRs, and IP cameras — but avoid pairing it with active power factor correction (APFC) power supplies unless you have confirmed compatibility, as some APFC units behave poorly on non-pure sine wave sources.
- 490 Joule Surge Energy Rating: The integrated surge suppression absorbs 490 joules of transient energy — solid protection against typical residential and light commercial line noise and lightning-induced surges. For facilities in areas with frequent direct lightning strikes or heavy industrial machinery on the same circuit, consider a dedicated surge suppressor upstream.
- 120V Input and Output (NEMA 5-15): Ships with a standard NEMA 5-15P plug and provides NEMA 5-15R outlets, so it drops into any standard North American circuit without adapters or rewiring. Input voltage range spans 120V at both 50 and 60 Hz — no manual voltage switching required for US and Canadian deployments.
- Audible Alarms — On Battery and Low Battery: The unit generates distinct audible alerts when it transitions to battery and again when battery reserve is critically low. In a surveillance closet with limited monitoring, these alarms provide a physical heads-up that administrators can hear without needing to be actively watching a dashboard.
- 45 dB Noise Level: At 45 dB, the BE700G3 is quiet enough for office environments and IT closets adjacent to occupied spaces. For comparison, that's roughly the ambient noise level of a quiet office — you'll notice it in a silent server room, but it won't be disruptive in a typical telecom or security equipment closet.
- 19.249 BTU/h Heat Dissipation: Thermal output is low, consistent with a standby topology that doesn't actively regulate power. In a tight equipment closet, this is a non-issue, but always verify rack or cabinet airflow when stacking multiple UPS units.
Integration and Compatibility
The BE700G3 is compatible with APC's PowerChute Personal Edition software for automated graceful shutdown on Windows and macOS — relevant when protecting a workstation-based video management software client. The unit connects to the host via USB. For larger surveillance environments running dedicated NVR appliances or edge servers, verify that your NVR vendor's shutdown integration supports APC's USB HID protocol or the PowerChute agent. The NEMA 5-15R outlets limit this unit to standard 15A circuit loads — it is not suitable for 20A dedicated circuits without an adapter, and adapters are generally not recommended for UPS applications. Pair with a PoE switch to protect the full camera-to-recorder chain, not just the recorder itself.

Frequently Asked Questions
Q: What is the difference between the BE700G3's standby topology and a line-interactive UPS?
A: The BE700G3 uses a standby (offline) design — it passes utility power directly to connected equipment and only activates its inverter when it detects an outage or severe voltage deviation. A line-interactive UPS continuously regulates voltage using an autotransformer, which provides better protection against sags and swells without switching to battery. For most computing loads in surveillance applications, standby is sufficient, but environments with chronic under-voltage or over-voltage conditions benefit from line-interactive designs.
Q: Will the BE700G3 work with power supplies that use active power factor correction (APFC)?
A: Potentially, but with a caution. The BE700G3 produces a pseudo sine wave (stepped approximation) during battery operation. Some APFC power supplies — commonly found in modern workstations and servers — can behave erratically or shut down when powered from a non-pure sine wave source. Verify your load's power supply specifications before deploying. If your equipment requires pure sine wave input, APC's Back-UPS Pro or Smart-UPS lines are the appropriate alternatives.
Q: How many outlets does the BE700G3 provide, and are all of them battery-backed?
A: The BE700G3 provides NEMA 5-15R outlets. Based on standard APC Back-UPS 700 configurations, a portion of the outlets are battery-backed while others are surge-only. Refer to the physical unit labeling or APC's product documentation for the exact outlet count and battery vs. surge-only designation, as outlet configurations can vary by manufacturing revision.
Q: What is the transfer time when the BE700G3 switches to battery?
A: The specified response time is 10 ms. Most ATX power supplies and switching mode power supplies used in computers and NVRs hold up for 20 ms or more during a power interruption, so 10 ms is within safe operating range for the vast majority of computing equipment. Industrial or specialized hardware with stricter hold-up requirements should be evaluated separately.
Q: Can the BE700G3 be used to power IP cameras directly?
A: The BE700G3 outputs standard 120V AC via NEMA 5-15R outlets, so it cannot directly power PoE cameras — those require a PoE switch or injector. However, it can protect the PoE switch that feeds your cameras, effectively providing battery backup to the entire camera run through the switch. Size your total load (switch + NVR + any other equipment) against the 420W capacity.
Q: Does the BE700G3 include USB connectivity for automated shutdown?
A: Yes. The BE700G3 includes a USB port that connects to a host computer running APC's PowerChute Personal Edition software, enabling automated graceful shutdown when battery runtime reaches a configured threshold — useful for protecting NVR recording integrity during extended outages.
I recommend the BE700G3 for surveillance closets where the primary concern is ride-through time for a clean shutdown rather than sustained runtime under heavy load. The 10 ms transfer time covers virtually every switching power supply I've encountered in NVR and edge-compute deployments, and 420W of real power gives you enough headroom for a mid-range recorder plus a small PoE switch without running the battery hot.
Technical Highlights:
- 490J Surge Rating: Absorbs meaningful transient energy — practical protection for equipment in commercial buildings where HVAC, elevators, or other inductive loads share circuits and create line noise.
- 10 ms Transfer Time: Fast enough for the hold-up time of virtually all ATX and server-class switching power supplies, which typically sustain 20 ms or longer — your NVR won't even register the switchover.
- 45 dB Acoustic Output: Low enough for occupied spaces and IT closets adjacent to offices — it won't generate noise complaints in a shared facilities room.
Deployment Considerations:
- Keep your connected load at or below 336W (80% of 420W rated output) — running close to rated capacity accelerates battery wear and shortens the replacement interval.
- The pseudo sine wave output is the key constraint: confirm that any workstation or server power supply in your deployment is tolerant of stepped waveform during battery operation before committing to this unit. APFC supplies in particular warrant a check.
The BE700G3 fits cleanly in a small-to-mid surveillance equipment closet: one NVR, one PoE switch, and a workstation client — all protected with enough ride-through time for graceful shutdown when the grid goes down. It's not the right tool for a 2kVA rack with a pure sine requirement, but for that specific scenario it's a well-matched, cost-efficient choice.
