RM11E PRO Series Online Rack UPS | 1–10 kVA

Introduction

RM11E PRO is ATENCO’s high-end 2U rack/tower VFI UPS built on three-level IGBT for cleaner, lower-loss power. It delivers PF 1.0 output with up to 95.5% online efficiency (ECO up to 98%) to cut heat, noise, and operating cost. A wide 110-300 Vac input, low THDi (≤3%), and zero-transfer switching protect sensitive

servers and edge IT- even on generators. Battery-flexible by design, the 15A fast charger speeds recovery and supports both LFP and VRLA strings.

scalable redundancy N+X up to 4 units, with smart fan control for quiet operation. Dual intelligent slots plus rich I/O (USB/RS-232/485, EPO) streamline remote monitoring, integration, and lifecycle management.
