Specifications

Compact centralized three-phase

The E91 is a compact, centralized online double-conversion UPS (10 to 20 kVA (30 to 40 kVA on the sibling frame) at 208Y/120V) with the electronics and VRLA batteries in one cabinet, built for fixed-capacity sites that don't need a modular system. Its unity output power factor (kVA = kW) gives, per XPC, up to 25% more critical load than typical UPS platforms at the same kVA rating.

How efficient is the E91?

Efficiency runs up to 94% online and up to 98% in ECO mode (Energy Star 2.0), it rides through 110% for an hour, and it can be locked to 50 or 60 Hz as a frequency converter.

How long does the E91 run on its batteries?

At full load an E91-10K runs 11 minutes on its internal batteries and 113 minutes with two EBP09-5 external cabinets.

Does the E91 have a cUL listing for Canada?

It's UL, cUL, FCC and TAA compliant (the cUL listing matters for Canadian sites) with a 4.3-inch colour touch display and an SNMP/relay card slot.

Batteries and battery cabinets for the XPC E91

Battery strings and cabinets depend on the configuration and runtime. Sealed VRLA blocks for Xtreme Power battery cabinets are in this sealed UPS battery range.
