Online Tower UPS 1–10 kVA
True online double-conversion (VFI) tower UPS from 1 to 10 kVA. TM11E delivers pure sine wave output, 0 ms online transfer and wide input voltage range – 110–300 Vac for 1–3 kVA and 110–286 Vac for 6–10 kVA models. Designed for servers, network switches, telecom shelters, edge IT and small office loads, with internal 12V VRLA batteries on standard models and external TC-series tower cabinets for runtime extension. CE, EMC, LVD and IEC 62040 standards available by series.
Engineered for Reliability
Online double-conversion topology, internal VRLA batteries with external cabinet runtime extension and parallel-capable 6-10 kVA models built for server rooms, telecom shelters and small office IT environments.
True Online Double-Conversion
VFI topology with DSP digital control. 0 ms online transfer and pure sine wave output help isolate servers, network switches and edge IT loads from voltage sags, brownouts and blackouts.
High Input Power Factor
Input PF ≥0.99 with active PFC helps reduce upstream electrical stress and supports better compatibility with cables, breakers and generator systems on project sites.
Up to 93.5% Efficiency
High online-mode efficiency: up to 92.3% on 1-3 kVA models and up to 93.5% on 6-10 kVA models. ECO mode reaches up to 98% in stable utility environments to reduce operating cost.
Scalable Battery Runtime
Internal 12V VRLA batteries are available on standard models. External TC-series tower battery cabinets extend runtime by model/configuration, sized according to load and target backup time.
Parallel-Capable (6-10 kVA)
Parallel-capable 6-10 kVA models support up to 4 units in N+X configuration for capacity scaling and redundant power architecture, subject to model configuration and project design.
Advanced Monitoring
LCD/LED display with USB, RS-232 and EPO as standard. Optional SNMP, relay and RS-485 cards support remote monitoring and control-room integration: TM220 for 1-3 kVA, TM550 for 6-10 kVA.
Expand Your System
Optional accessories for runtime extension, remote monitoring and maintenance bypass support – available by model.
External Battery Cabinets
