It ships without an internal battery: the unit connects to an external 96VDC battery bank that you size to match your required backup time. This makes the HD3KS a natural fit for system integrators and project buyers who design their own DC banks, prefer local battery sourcing, or need a specific runtime that standard built-in configurations cannot deliver.
-
Zero transfer time — online double conversion means no switchover gap during a mains failure. -
Ultra-wide input range — operates from 90–300VAC and 40–70Hz, dramatically reducing battery discharge in unstable grids. -
Flexible runtime — the external battery bank is specified by you, for your backup-time target, not limited by a built-in pack. -
Lower cost of entry — pay only for the UPS; source batteries locally or through us, whichever serves your project better.
