APC by Schneider Electric BK350EI 350VA Desktop UPS
Overview
The APC by Schneider Electric BK350EI is a 350 VA desktop uninterruptible power supply designed to keep small commercial equipment running through brief power outages and protect connected devices from voltage irregularities. At 230V output, the BK350EI targets markets wired for European and international mains voltage — making it a practical fit for access control panels, small NVRs, network switches, or point-of-sale terminals that cannot tolerate unexpected shutdowns.
The beige desktop form factor requires no rack space and no dedicated enclosure — place it on a shelf or floor adjacent to the equipment it protects. For deployments where a full rack-mount UPS is overkill, this unit handles the load without the footprint or cost premium.
Key Features
- 350 VA / 230V Output: Sized for light commercial loads — a small NVR, a PoE switch, or an access control panel. The 230V output matches international mains standards, so no step-down transformer is needed in EU and compatible regions.
- Sealed Lead-Acid Battery: Lead-acid chemistry is field-proven, widely serviceable, and replaceable without returning the unit. When the battery reaches end-of-life, a qualified technician can swap it on-site rather than replacing the entire UPS — a practical consideration for long-deployed installations.
- Desktop / Zero-Rack-Unit Form Factor: With 0 rack units consumed, the BK350EI installs wherever floor or shelf space allows. No rack rails, no cage nuts, no rack-mount kit required.
- 3.8-Foot Power Cord: The 3.8 ft cord provides enough reach for most equipment-room placements without requiring an extension — keeps the installation clean and avoids cord management issues near sensitive equipment.
- Beige Housing: Neutral color integrates into office and light-commercial environments without drawing attention — relevant in customer-facing areas such as reception desks or retail counters where rack equipment would be intrusive.
Integration & Compatibility
The BK350EI outputs 230V AC, which aligns with standard mains voltage across Europe, the Middle East, Africa, and parts of Asia-Pacific. Before deploying, confirm that all connected equipment is rated for 230V input — North American 120V devices are not compatible without a transformer. The unit is suited for small security and networking loads: confirm total VA draw of connected devices stays within the 350 VA capacity to ensure runtime margin.
For broader APC by Schneider Electric power protection options including higher-capacity models and rack-mount configurations, review the full product line. If you are sizing power backup for a multi-camera surveillance installation, the UPS and power backup category covers a range of VA ratings and form factors. Pair this unit with a managed PoE switch on the load side to keep IP cameras online during brief outages. For guidance on sizing backup power for security systems, consult a power protection planning guide.
Note: This product carries a California Proposition 65 warning for cancer and reproductive harm. Review applicable safety guidelines before installation in occupied spaces.
Frequently Asked Questions
Q: What is the output voltage of the BK350EI?
A: The BK350EI outputs 230V AC, designed for international mains voltage standards used across Europe, the Middle East, Africa, and compatible Asia-Pacific markets.
Q: What type of battery does the BK350EI use?
A: It uses a sealed lead-acid battery. Lead-acid UPS batteries are field-replaceable, which means the battery can be swapped on-site at end-of-life without replacing the entire unit.
Q: Does the BK350EI require rack mounting?
A: No. The BK350EI is a desktop unit with a 0 rack-unit rating — it is designed for floor or shelf placement and does not require rack rails or a rack enclosure.
Q: What is the VA capacity of the BK350EI?
A: The BK350EI is rated at 350 VA. Before connecting equipment, add up the VA or watt ratings of all devices on the load side to ensure total draw stays within this capacity and provides adequate runtime.
Q: Is the BK350EI suitable for North American 120V installations?
A: No. The BK350EI outputs 230V and is intended for international markets. North American 120V equipment is not compatible without a step-down transformer.
The BK350EI is a 230V, 350 VA desktop UPS — and the voltage spec is the first thing to nail down before recommending it. I've seen installers order a unit, receive it, and then realize their NVR or switch is spec'd for 120V. This is an international-market unit; if you're deploying in North America, it is the wrong product. For EU, Middle East, or APAC sites running 230V mains, it fits the bill for small loads.
Technical Highlights:
- 350 VA / 230V: Adequate for a single small NVR plus a basic PoE switch, or an access control panel with a reader or two. Keep load under 80% of rated VA — around 280 VA — for reasonable runtime margin.
- Sealed Lead-Acid Battery: Field-replaceable without depot return. For security installations with multi-year service contracts, this matters — a technician can swap the cell on-site rather than pulling and shipping the unit.
- Zero-RU Desktop Form Factor: No rack required. Mount adjacent to the equipment or tuck it on a shelf in an IDF closet. The 3.8 ft cord gives you enough reach for most equipment-room layouts without extension cords.
Deployment Considerations:
- Verify every device on the load side is rated for 230V input before wiring. The BK350EI does not auto-sense or switch voltages — connecting 120V equipment will damage it.
- The California Prop 65 warning applies to this unit. For installations in California or any occupied space where Prop 65 compliance is audited, document accordingly and follow applicable handling guidelines for lead-acid battery disposal at end-of-life.
This unit is the right call for small international-market security closets — an EU branch office running a compact NVR and door controller, for example — where a rack-mount UPS would be overkill and a 350 VA desktop keeps the critical gear online through brief grid interruptions without overcomplicating the install.
