TM33E 50–200 kVA UPS FAQ

Answers about TM33E 50–200 kVA high-capacity 3:3 three-phase tower UPS architecture, PF 1.0 output, parallel operation, VRLA / LFP battery systems, monitoring and Load Bus Synchronization.

What is the TM33E 50–200 kVA UPS?
TM33E 50–200 kVA is a high-capacity 3:3 online double-conversion VFI three-phase tower UPS platform. It accepts three-phase input and delivers protected three-phase output at output PF 1.0 (kW = kVA), using 3-Level IGBT inverter topology and DSP digital control. It is designed for mission-critical data centers, telecom core sites, industrial facilities and critical infrastructure, with capacities of 50, 60, 80, 100, 120, 160, 180 and 200 kVA.
What is the difference between TM33E 10–40 kVA and TM33E 50–200 kVA?
Both are TM33E 3:3 online double-conversion three-phase tower UPS systems with PF 1.0 output. The 10–40 kVA range covers smaller three-phase installations and supports parallel operation up to 4 units. The 50–200 kVA range is the high-capacity platform with larger cabinets, charger current up to 60A, 7-inch TFT touchscreen HMI, programmable ±180 to ±300 Vdc battery bus, parallel operation up to 8 units and Load Bus Synchronization for dual-bus designs. Choose 10–40 kVA for smaller three-phase loads; choose 50–200 kVA for larger data center, telecom, industrial and infrastructure projects.
Can the TM33E 50–200 kVA be paralleled for redundancy?
Yes. TM33E 50–200 kVA supports direct parallel operation for capacity expansion or N+X redundancy up to 8 units, subject to project design. Shared-battery parallel configuration is supported by configuration. The parallel kit, including cables and configuration, is specified at order. A Load Bus Synchronization (LBS) port is available for dual-bus or coordinated multi-system designs, including STS-supported architectures.
What battery options does the TM33E 50–200 kVA support?
TM33E 50–200 kVA uses external battery systems and supports VRLA lead-acid battery strings or LFP battery cabinets by project configuration. VRLA strings are configurable from 30 to 50 pcs of 12 V blocks, with a programmable DC bus from ±180 to ±300 Vdc. For full PF 1.0 output, 36–50 pcs are used; 32–34 pcs carry PF 0.9 derating, and 30 pcs carries PF 0.8 derating. Charger current scales by model up to 60A. ATENCO engineers size the battery system according to UPS capacity, load level and target backup time.
Can the TM33E 50–200 kVA run on a generator?
Yes. TM33E 50–200 kVA supports a wide 138–485 Vac input window and 40–70 Hz input frequency, with input walk-in to help limit inrush, supporting generator-backed sites and unstable utility conditions when the generator is properly sized and configured. Input PF ≥0.99 and input THDi ≤3% help reduce upstream electrical stress. DC cold-start is supported for startup from battery without utility.
What monitoring options does the TM33E 50–200 kVA support?
TM33E 50–200 kVA provides a 7-inch TFT colour touchscreen HMI with mimic diagram and event history, plus USB, RS-232, RS-485, dry contact, EPO / REPO and intelligent-slot communication. The optional TM550 SNMP card enables network monitoring, web access, event alerts and NMS / BMS integration; relay card options are available for dry-contact integration. Modbus RTU via RS-485 supports BMS / SCADA integration by configuration.
What is LBS synchronization on the TM33E 50–200 kVA?
LBS, or Load Bus Synchronization, is available on TM33E 50–200 kVA for dual-bus or synchronized multi-system designs. It coordinates output synchronization between UPS systems in applications such as dual power paths or STS-supported architectures. Availability and configuration depend on project design.
Does TM33E 50–200 kVA support lithium batteries?
Yes. TM33E 50–200 kVA supports VRLA lead-acid battery strings and LFP battery cabinets by project configuration. LFP systems require compatible cabinet design, BMS communication and project-specific charging and runtime settings confirmed during sizing.
Is TM33E 50–200 kVA transformer-based?
No. TM33E 50–200 kVA is a transformer-less 3:3 online double-conversion UPS platform. For transformer-based or galvanic-isolation requirements, use the TM33-ET range, selected according to project isolation and electrical requirements.
Which applications is the TM33E 50–200 kVA not recommended for?
TM33E 50–200 kVA is a high-capacity three-phase tower UPS; it is not the right choice when the protected load requires single-phase output. For single-phase UPS loads, use TM11E or RM11E; for sites with three-phase supply but single-phase critical loads, use TM31E or RM31E 3:1. For smaller three-phase loads below 50 kVA, use TM33E 10–40 kVA. For transformer-based galvanic isolation, use TM33-ET. Medical-grade or isolation-specific projects should be reviewed against the project’s electrical, certification and isolation requirements.
