APC by Schneider Electric BK325I Back-UPS CS 325VA Uninterruptible Power Supply
Overview
The APC by Schneider Electric BK325I is a 325VA / 210W line-interactive uninterruptible power supply built for protecting small office equipment, network devices, and security appliances in environments where brief power outages or surges can cause real problems. The BK325I delivers 210 watts of continuous output power — enough to keep a compact NVR, a PoE switch, or a workstation running through short outages while giving you time to save data and shut down gracefully. Its sealed lead-acid (VRLA) battery requires no maintenance and recharges fully in six hours after a discharge, so the unit is ready for the next event without any manual intervention.
With a 320-joule surge energy rating, this UPS absorbs transient voltage spikes that would otherwise reach connected equipment. For security deployments where an NVR or access control panel going down mid-event means lost footage or unlocked doors, that protection matters more than the headline VA rating. The unit ships in a compact, beige desktop form factor with three IEC 60320 output connectors — a common configuration in European and international deployments where IEC outlets are standard on rack equipment and desktop power strips alike.
Key Features
- 210W / 325VA output capacity: Sized correctly for a compact NVR plus a small managed switch, or a single workstation. Know your load before you order — 210W is the hard ceiling; exceeding it trips the overload protection.
- 320-joule surge energy rating: Absorbs voltage transients at the outlet before they reach connected gear. In facilities with aging electrical infrastructure or where lightning is a seasonal risk, this is your first line of defense for IEC-connected devices.
- Sealed Lead Acid (VRLA) battery: Valve-regulated sealed construction means no water topping, no venting concerns in enclosed cabinets, and no spill risk. It operates correctly in any orientation.
- 6-hour full recharge: After a full discharge, the BK325I is back to 100% capacity in roughly six hours. For sites with recurring brownouts, plan recharge cycles — back-to-back outages within the same shift could leave the battery partially depleted.
- 3 × IEC 60320 output connectors: Standard IEC outlets support the C13/C14 power cords common on network equipment, NVRs, and access control panels in international markets. No US NEMA outlets — confirm your equipment uses IEC connectors before deploying.
- 0–40°C operating temperature range: Covers standard indoor environments, wiring closets, and light-industrial spaces. Not rated for unheated outdoor enclosures or environments that exceed 40°C — plan accordingly for server rooms without adequate cooling.
- 0–95% operating relative humidity: Wide humidity tolerance handles coastal and humid-climate installations without special enclosure requirements, provided condensation is not present.
- Certifications — CE, VDE, EN 50091-1, EN 50091-2, C-tick, GOST: Multi-jurisdiction certifications confirm the unit meets safety and EMC requirements for European, Australian, and Russian markets. Verify local compliance requirements for your specific deployment region.
Integration & Compatibility
The BK325I does not include a network management card slot (SmartSlot) or a SmartConnect port, so remote monitoring and automated graceful shutdown require a separate UPS management solution or manual procedures. For deployments where unattended shutdown is required — a remote NVR location, for example — factor in that limitation before specifying this unit. If network-managed shutdown is a requirement, step up to a model in the APC Back-UPS Pro or Smart-UPS line with SmartSlot support.
The three IEC 60320 output connectors pair naturally with the power cords used on compact network video recorders, managed PoE switches, and access control panels common in European security installations. No NEMA 5-15 outlets are present — this unit is not configured for North American power infrastructure. For mixed-outlet requirements, a step-up model or a separate outlet adapter strategy is needed.
At 0.325 kVA, this UPS is not intended to back up high-wattage equipment. A single mid-range PoE switch running at 60–80W plus a compact NVR at 40–60W brings you close to the 210W ceiling. Calculate your actual connected load, not nameplate maximums, to avoid nuisance tripping.
Frequently Asked Questions
Q: What is the maximum load the BK325I can support?
A: The BK325I supports a maximum output of 210 watts (325VA). Exceeding this will trigger overload protection. Calculate your actual connected load — including inrush current — before deploying.
Q: Does the BK325I include a management card or network monitoring port?
A: No. The BK325I does not include a SmartSlot for management cards, and there is no SmartConnect port. Remote monitoring and automated shutdown are not supported on this unit without an external solution.
Q: What type of battery does the BK325I use, and does it require maintenance?
A: It uses a sealed lead-acid (VRLA) battery. This is a maintenance-free design — no water topping, no venting requirements, and no spill risk. The battery recharges fully in approximately 6 hours after a discharge.
Q: What outlets does the BK325I provide?
A: The BK325I provides 3 × IEC 60320 output connectors. There are no NEMA (North American) outlets. Confirm your equipment uses IEC-compatible power cords before ordering.
Q: What certifications does the BK325I carry?
A: The BK325I is certified to C-tick, CE, EN 50091-1, EN 50091-2, GOST, and VDE — covering European, Australian, and Russian market safety and EMC requirements.
Q: What is the operating temperature range for the BK325I?
A: The BK325I operates from 0°C to 40°C (32°F to 104°F). Storage is rated from -15°C to 45°C. It is not suitable for unheated outdoor enclosures or spaces exceeding 40°C.
The BK325I is a unit I specify when the deployment is international and the load is modest — specifically when you have a compact NVR and a small PoE switch sitting in a wiring closet that needs ride-through protection during brief outages. At 210W continuous output, this UPS isn't trying to be everything; it's sized for a defined role, and within that role it does it reliably with zero battery maintenance thanks to the VRLA sealed cell.
Technical Highlights:
- 210W / 325VA output: Enough headroom for a compact NVR (~50W) plus a 4–8 port PoE switch (~80W) with margin left. Push past 210W and the overload protection trips — know your actual wattage, not nameplate ratings.
- 320J surge rating: Handles transient spikes at the outlet. Not a substitute for whole-facility surge protection, but meaningful for connected IEC devices in markets with variable grid quality.
- 6-hour recharge on VRLA chemistry: After a full discharge, you get full capacity back in about six hours. In environments with recurring brownouts, back-to-back events within the same working day may leave the battery short — that's a site-planning consideration, not a product defect.
Deployment Considerations:
- No SmartSlot, no SmartConnect — remote shutdown and network-based monitoring are off the table without an external solution. For unmanned remote sites, this is a real limitation to flag before specifying.
- IEC 60320 outlets only — three of them. This is an international-market unit. North American deployments with NEMA power cords will need adapters or a different model entirely.
This is the right call for a European or international small-site deployment — a retail location, a small access control head-end, or an international branch office NVR — where the load fits under 210W, IEC outlets are standard, and battery maintenance isn't a viable option.
