TM33E SERIES

Three-Phase Tower UPS 10–40 kVA

Three-phase in / three-phase out online double-conversion (VFI) topology with IGBT technology and DSP control. PF 1.0 standard output (kW = kVA), 7-inch touchscreen HMI, and parallel capability up to 4 units for N+X redundancy.

Three Phase (3:3) PF 1.0 Tower Efficiency up to 94.5%

Engineered for Reliability

Advanced features designed to keep your critical systems running without interruption.

True Online Double-Conversion

VFI topology with 0ms transfer time from AC to battery mode. Pure sinewave output protects sensitive equipment.

High Input Power Factor

≥0.99 input PF with active PFC reduces upstream cable sizing and generator requirements.

Up to 92% Efficiency

High AC mode efficiency (up to 92% on 2-3 kVA, up to 93.5% on 6-10 kVA) plus ECO mode for maximum energy savings.

Scalable Battery Runtime

Internal batteries standard (1-10 kVA). External battery cabinets available for extended runtime requirements.

Parallel Redundancy

Up to 4 units in parallel (6-10 kVA) for N+X redundancy in mission-critical applications.

Advanced Monitoring

LCD/LED display with USB, RS-232, EPO standard. Optional SNMP, relay, and RS-485 cards.

Expand Your System

Optional accessories to extend capability and integrate with your infrastructure.

External Battery Cabinets

TC080120N external battery cabinet for extended runtime on all TM33E 10–40 kVA models.

Maintenance Bypass Switch

Allows safe UPS maintenance without interrupting power to connected loads.
