TM66E Compact Modular Three-Phase UPS 30–75 kVA
TM66E Compact 30–75 kVA is a transformer-less online double-conversion modular three-phase UPS platform with built-in hot-swappable VRLA battery modules for compact critical-power projects. It uses 10 / 15 / 20 / 25 / 30 kVA hot-swappable power modules, 3-level topology, output PF 1.0, up to 95.8% AC-mode efficiency, wide 138–485 Vac input, input PF ≥0.99, input THDi ≤3%, 0 ms AC-to-battery transfer, Load Bus Synchronization (LBS), and parallel operation up to 6 units by configuration. A 7″ colour touchscreen is standard, with 10″ optional by configuration.
Modular UPS with Built-In VRLA Battery Modules
TM66E Compact 30–75 kVA is an online double-conversion modular three-phase UPS designed for smaller modular projects where internal-battery integration removes the need for an external battery cabinet. Hot-swappable power, bypass, monitoring and ECU control modules support zero-downtime maintenance and capacity expansion within the cabinet.
Built-In Battery Module Design
Up to 6 internal battery groups can be installed inside the UPS cabinet by configuration, reducing the need for an external battery cabinet for standard autonomy requirements. The system uses VRLA lead-acid maintenance-free batteries at ±240 Vdc nominal, with hot-swappable battery modules supported up to 24 modules per cabinet by configuration.
Hot-Swappable Modular Architecture
Power, bypass, monitoring and ECU control modules are hot-swappable. Power modules in 10 / 15 / 20 / 25 / 30 kVA ratings can be added, removed or replaced within cabinet capacity, supporting capacity expansion and reduced-downtime maintenance by procedure.
PF 1.0 Output / Up to 95.8% Efficiency
Output PF 1.0 (kW = kVA) delivers full usable kW from 30 to 75 kVA. AC-mode efficiency reaches up to 95.8% with 3-level transformer-less topology, while ECO and HECO modes are available up to 99% for energy saving in suitable utility conditions.
Parallel up to 6 Units & LBS
Direct parallel operation supports capacity expansion or N+X redundancy up to 6 units, subject to project design. Shared-battery parallel configuration is supported. Load Bus Synchronization (LBS) supports dual-bus or coordinated multi-system critical-power architectures.
7″ Touchscreen HMI & SNMP / Modbus
7-inch TFT touchscreen is standard, with 10-inch optional by configuration. The system supports history logs and fault logs. Communications include RS-232, RS-485, parallel, LBS, BMS and dry contact. Optional TM550 SNMP card supports network monitoring, and Modbus RTU via RS-485 supports BMS / SCADA integration. FW / SW online upgrade is supported in bypass mode.
Wide Input & Generator Compatibility
Wide 138–485 Vac input range supports unstable utility conditions, with operation derated to 40% load below 305 Vac. Input PF ≥0.99 and input THDi ≤3% help reduce upstream electrical stress. Power Walk-In limits start-current impact for generator-backed sites when the generator is properly sized and configured.

TM550 SNMP Network Card
Optional TM550 SNMP card fits the intelligent slot and enables network monitoring, web access, event alerts, shutdown management and NMS / BMS integration. RS-485 / Modbus RTU supports BMS / SCADA integration by configuration.
Parallel Kit / LBS Synchronization
Parallel kits support capacity expansion and N+X redundancy up to 6 units by configuration. Load Bus Synchronization (LBS) supports dual-bus or coordinated multi-system designs for critical-power architectures.
