APC Easy UPS 3S 10 kVA 400 V Three-Phase UPS (3:3) for Internal Batteries

Three-phase in, three-phase out – no step-down transformer eating headroom. This 10 kVA unit takes a 400 V feed (or 380/415 V) and puts clean 400 V back out when the mains drops. IP20 rated with a dust filter and conformance-coated boards, so it's not fussy about the environment. 60 dBA means it won't rattle the electrical room. Supplied without batteries, so you slot in E3SBT4 or E3SBTH4 strings for exactly the runtime your load needs. No overbuying, no under-protecting
