APC by Schneider Electric BE400-KR Back-UPS ES 400VA 220V Korean
Overview
The APC by Schneider Electric BE400-KR is a 400VA / 220V uninterruptible power supply from the Back-UPS ES line, configured specifically for the Korean market. It provides battery backup and surge protection for connected equipment — keeping small workstations, network devices, and security components online through brief outages and protecting them from power quality events such as surges and line noise. The BE400-KR (often searched as BE400 KR) is a compact, line-interactive class device suited to environments where a single outlet run needs backup coverage without a rack-mount or high-capacity system.
For integrators deploying APC by Schneider Electric power protection equipment in Korean-market facilities, the BE400-KR fits single-node protection requirements — a standalone access controller, a PoE injector feeding a camera, or a small network switch where a brief power interruption would cause a gap in recording or door access. It is not a substitute for a rack-mount UPS on a multi-camera NVR stack; for that, size up within the Back-UPS Pro or Smart-UPS lines.
Key Features
- 400VA / 220V Rating: Sized for single-node loads — sufficient to carry a small switch, a PoE injector, or an access control panel through a typical 5–10 minute outage, giving connected devices time to complete a clean shutdown or survive a momentary grid event.
- Korean Market Configuration: Outlet type, voltage standard, and regulatory compliance are set for 220V Korean infrastructure — specifying this variant avoids outlet-adapter workarounds and ensures the unit operates within its designed voltage window.
- Surge Protection: Beyond battery backup, the Back-UPS ES line filters surges and line noise from connected loads, which matters in facilities where power quality affects the reliability of network equipment and edge devices.
- Compact Form Factor: The Back-UPS ES series is desktop/tower format — deployable on a shelf or floor near the equipment it protects, without requiring rack space or a dedicated electrical room.
Integration & Compatibility
The BE400-KR is compatible with APC's PowerChute Personal Edition software for automated graceful shutdown of a connected PC or server. For network infrastructure protection in small deployments, pair it with the device it needs to keep live — a PoE switch powering one or two cameras, or an access controller at a remote door. For larger installations requiring runtime management, load segmentation, or network-card monitoring, consider moving to the Smart-UPS line within the APC catalog.
Frequently Asked Questions
Q: What does the 400VA rating mean in practical terms?
A: 400VA is the maximum load the UPS can support. For typical security devices — a small PoE switch drawing 60–80W, or an access controller drawing 20–30W — the BE400-KR provides several minutes of runtime during an outage. Actual runtime depends on the connected load; lighter loads run longer.
Q: Is the BE400-KR designed for the Korean market specifically?
A: Yes. The -KR suffix designates the Korean market variant, configured for 220V infrastructure and Korean outlet standards. Do not substitute a different regional variant without confirming voltage and outlet compatibility.
Q: Can the BE400-KR protect a PoE switch powering IP cameras?
A: A small PoE switch powering one or two cameras is within the BE400-KR's capacity range, provided the total load stays within 400VA. For switches powering multiple high-wattage cameras, calculate the total draw before specifying this unit.
Q: Does the BE400-KR include software for automatic shutdown?
A: The Back-UPS ES line is compatible with APC's PowerChute Personal Edition for automated graceful shutdown of a connected PC or server during extended outages.
The BE400-KR comes up when integrators are closing out a Korean-market deployment and need to cover the last unprotected node — a door controller at the end of a long cable run, or a PoE injector in a remote IDF closet. At 400VA / 220V, it is a single-node device: right-sized for one piece of infrastructure, not a rack shelf of equipment.
Technical Highlights:
- 400VA Capacity: Enough headroom for a small PoE switch or access controller — gear that must stay live during a grid event to avoid a recording gap or an unlocked door state.
- 220V Korean Configuration: Specifying the -KR variant ensures the unit operates within its designed voltage window on Korean infrastructure; using a mismatched regional SKU risks under- or over-voltage operation.
- Back-UPS ES Line: The ES series prioritizes simplicity — no network management card, no load-segment switching. That's appropriate for edge nodes that don't need centralized UPS monitoring.
Deployment Considerations:
- Size the load carefully: 400VA is the ceiling, not a target. Derate to 60–70% of rated capacity for best battery longevity — that means keeping connected loads under roughly 240–280W in practice.
- This unit is not network-manageable out of the box. If your deployment requires SNMP monitoring or remote graceful shutdown across multiple UPS units, the Smart-UPS line with a network management card is the correct path instead.
The BE400-KR is the right call for a single protected node in a Korean-market physical security deployment — a remote access controller, a single-camera PoE injector, or a small edge switch — where the goal is surviving a brief outage without a site visit.
