Mid-Range Modular UPS with VRLA & Lithium Support
TM66E Modular 40–600 kVA is a transformerless online double-conversion modular three-phase UPS platform for medium-to-large data centers, telecom, infrastructure and industrial critical-power projects requiring scalable capacity, VRLA or lithium battery flexibility and high-efficiency operation. 40 / 50 / 60 kVA hot-swappable power modules support capacity expansion and reduced-downtime maintenance by approved procedure.
VRLA & Lithium Battery Support
Compatible with external VRLA lead-acid or lithium battery systems by project configuration. The 360–600 Vdc battery bus supports both chemistries with project-specific cabinet design, BMS communication and runtime targets. Charger current is up to 20 A by model and configuration.
40 / 50 / 60 kVA Hot-Swappable Power Modules
Power, bypass, monitoring and ECU control modules are hot-swappable. Power modules in 40 / 50 / 60 kVA ratings can be added, removed or replaced within cabinet capacity, supporting capacity expansion and reduced-downtime maintenance by approved procedure. Cabinet capacity scales from 40 to 600 kVA by module and cabinet configuration.
PF 1.0 Output / Up to 96% Efficiency
Output PF 1.0 (kW = kVA) delivers full usable kW across the 40–600 kVA range. AC-mode efficiency reaches up to 96% with 3-level IGBT 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 mimic diagram, 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.
