APC Easy UPS 3S 15 kVA 400V 3:1 UPS, 1 internal 7Ah modular battery string, expandable to 3

The APC Easy UPS 3S 15 kVA (model E3SUPS15K3IB1) is a 3-phase, double-conversion online UPS with internal sealed lead‑acid batteries that provides approximately 9 minutes of runtime at rated load. Designed for data centers and electrical rooms, it delivers 15 kVA (15 000 W) output power, an IP20 enclosure, and a compact footprint that simplifies installation and front-access maintenance. The unit includes a dust filter and conformance-coated boards for improved reliability in harsh environments and supports parallel configuration for increased capacity or redundancy.

Advantages

The UPS features a wide input voltage window to minimize battery use during voltage disturbances, replaceable dust filters for protection in dusty environments, and an ECO mode that improves operating efficiency by bypassing unused components under good power conditions. Front-access servicing, integrated input/output/bypass breakers and an Emergency Power Off (EPO) switch simplify installation and maintenance. Optional SNMP monitoring enables remote management via the UPS web interface or EcoStruxure IT platforms.

How to use

Position the UPS in the electrical room or rack space using its compact footprint and front access. Follow the included installation guide to connect input, output and bypass breakers and wire the Emergency Power Off (EPO) circuit if required. Install the replaceable dust filter where environmental conditions demand it. For network monitoring, install the optional SNMP card and configure access through the built‑in web interface or EcoStruxure IT tools. Perform the Easy Loop Test to verify UPS performance before connecting critical loads.

Recommendations

For accurate battery runtime at your specific load, consult the runtime charts in the product documents. Schedule regular front-access maintenance, replace dust filters as needed, and consider parallel units for higher capacity or redundancy. Use ECO mode when power quality is stable to maximise efficiency without compromising protection.
