Description

The APC Easy UPS 3S is a three-phase double-conversion online UPS delivering 40 kVA / 40,000 W of continuous power protection for small and medium businesses with demanding critical loads. Designed for use with external battery frames (no internal batteries included), this floor-standing tower unit achieves up to 96% efficiency in double-conversion mode and up to 99% in ECO mode, with a unity power factor (1.0) ensuring every kVA equals every kW. Parallel operation of up to four units supports capacity scaling or N+1 redundancy, while the built-in maintenance bypass allows uninterrupted servicing.

The Easy UPS 3S features a pure sine wave output, temperature-compensated battery charging, automatic bypass and overload protection (150% for 1 minute), and conformal-coated PCBAs for durability in challenging environments. An intuitive LCD interface simplifies configuration and real-time monitoring, and SNMP network management enables integration with EcoStruxure IT for remote visibility and control. Green Premium certified and RoHS compliant, it suits server rooms, data closets, and industrial installations requiring scalable three-phase protection. In stock and ready to ship from iptrading.com.au — order now for fast dispatch.

FAQs

Q: Why does this UPS ship without internal batteries?
A: The E3SUPS40KH is the external-battery variant of the Easy UPS 3S 40 kVA. At this power class, runtime requirements vary significantly between deployments, so APC offers this model without internal batteries. You pair it with compatible APC external battery frames to achieve your target runtime, giving you full control over capacity and cost.

Q: Can I parallel multiple E3SUPS40KH units for redundancy or more capacity?
A: Yes. Up to four Easy UPS 3S units can be operated in parallel, supporting both capacity expansion (up to 160 kVA) and N+1 redundancy configurations. In 1+1 parallel mode, common battery sharing is also supported to reduce total battery costs.

Q: What is the difference between double-conversion mode and ECO mode?
A: In double-conversion (online) mode, all power passes through the inverter continuously, providing zero transfer time and complete isolation from mains disturbances — ideal for sensitive IT and industrial loads. ECO mode routes power through the bypass path when conditions are stable, achieving up to 99% efficiency; the inverter takes over immediately if power quality degrades.

Q: Is the Easy UPS 3S 40 kVA compatible with APC's EcoStruxure IT platform?
A: Yes. The E3SUPS40KH supports SNMP network management and is fully compatible with APC's EcoStruxure IT ecosystem, enabling remote monitoring, alerting, and integration into a broader data centre management environment.

Q: Is this UPS suitable for Australian three-phase installations?
A: Yes. The Easy UPS 3S 40 kVA supports 380–415 V three-phase input (with a wide range of 304–477 V), making it fully compatible with Australian commercial and industrial three-phase power infrastructure.

Q: Can I purchase the E3SUPS40KH in Australia from IP Trading, and how quickly will it ship?
A: Yes. IP Trading stocks the APC Easy UPS 3S 40 kVA (E3SUPS40KH) in Australia and offers fast dispatch. Order through iptrading.com.au and our team can assist with compatibility, parallel configuration advice, and external battery frame selection.
