APC E3SUPS15K3I | Easy UPS 3S 15 kVA Online UPS, 3:1, For External Batteries

Q: Does the APC E3SUPS15K3I include internal batteries?
A: No. The E3SUPS15K3I is designed exclusively for use with external battery modules, allowing organisations to size runtime independently of the UPS unit itself. This makes it ideal for deployments requiring extended or scalable backup duration.

Q: What does the 3:1 configuration mean for this UPS?
A: The 3:1 designation means the UPS accepts three-phase input power (380/400/415 V) and delivers single-phase output (220/230/240 V). This is commonly used in environments where the building power feed is three-phase but the critical loads — such as servers and network equipment — require single-phase power.

Q: Can this UPS be used with a generator?
A: Yes. The Easy UPS 3S features a wide input voltage range (304–477 V) and low input THDi (<4%), which reduces harmonic stress on generators and makes it well-suited for generator-backed installations common in data centres and industrial facilities.

Q: What is the efficiency of the E3SUPS15K3I and how does ECO mode work?
A: In standard double-conversion mode, the UPS operates at greater than 96% efficiency. ECO mode increases this to greater than 99% by allowing the load to run on conditioned mains power while the inverter remains on standby, switching instantly if the input falls outside acceptable parameters.

Q: Does the E3SUPS15K3I support remote network management?
A: Yes. The unit supports SNMP, enabling integration with enterprise network management systems for remote monitoring, alerting, and status reporting — essential for unattended data centre and critical infrastructure deployments.
