19″ Rack-Cabinet Modular PF 1.0 Output Up to 95.8% Efficiency Parallel up to 8 Cabinets Hot-Swappable Power Modules

Rack-Cabinet Modular UPS with Flexible External Battery

TM66E Modular 10–150 kVA is an online double-conversion rack-cabinet modular three-phase UPS designed for scalable data-center, telecom, infrastructure and critical-power projects where external battery configuration, flexible runtime and compact rack-cabinet footprint matter. 10–30 kVA hot-swappable power modules support capacity expansion and reduced-downtime maintenance, while the external VRLA battery system enables longer runtime flexibility than built-in battery designs.

19″ Rack-Cabinet Modular Design

19″ rack-cabinet architecture with external battery system, designed for data-center rooms, network rooms and scalable modular UPS projects. The UPS cabinet uses a compact footprint without built-in battery modules, allowing runtime to be configured separately through external VRLA battery strings.

10–30 kVA Hot-Swappable Power Modules

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 approved procedure. Cabinet capacity scales from 10 to 150 kVA by module and cabinet configuration.

External VRLA Battery Configuration

External VRLA battery strings provide flexible runtime configuration. Battery strings can use 30–50 pcs of 12 V blocks, with programmable ±180 to ±300 Vdc battery bus by configuration. For full PF 1.0 output, 36–50 pcs are used; 32–34 pcs operate at PF 0.9 derating and 30 pcs at PF 0.8 derating. Charger current is up to 18 A.

PF 1.0 Output / 3-Level IGBT

Output PF 1.0 (kW = kVA) delivers full usable kW across the 10–150 kVA range when battery configuration supports full rating. AC-mode efficiency reaches up to 95.8% with 3-level IGBT topology. Output THDv is ≤1% with linear load and ≤3% with non-linear load. Energy-saving mode is available by configuration for stable utility conditions.

Parallel up to 8 Cabinets & LBS

Direct parallel operation supports capacity expansion or N+X redundancy up to 8 cabinets, subject to project design. Load Bus Synchronization (LBS) supports dual-bus or coordinated multi-system critical-power architectures. Shared-battery parallel configuration is supported by configuration.

Dual DSP / SNMP / RS485 / BMS

Dual DSP control supports reliable operation and system control. 7″ colour touchscreen is standard, with 10″ optional by configuration. Communications include SNMP, RS-232, RS-485, dry contact, BMS, EPO and REPO by configuration. Power Walk-In limits start-current impact for generator-backed sites when the generator is properly sized and configured.

TM66E Modular 10–150 kVA UPS FAQ

Answers about TM66E Modular 10–150 kVA rack-cabinet modular UPS architecture, external VRLA battery configuration, PF 1.0 output, hot-swappable power modules, N+X parallel operation and Load Bus Synchronization.

What is the TM66E Modular 10–150 kVA UPS?
TM66E Modular 10–150 kVA is a rack-cabinet modular three-phase online double-conversion UPS platform with external VRLA battery configuration. It uses 3-level transformer-less topology, dual DSP control and 10 / 15 / 20 / 25 / 30 kVA hot-swappable power modules. Output PF is 1.0 when the battery configuration supports full rating, with AC-mode efficiency up to 95.8% and output THDv ≤1% linear / ≤3% non-linear. Cabinet capacity is configured by module size and cabinet arrangement up to 150 kVA, with external VRLA battery strings using 30–50 pcs of 12 V blocks per string and programmable ±180 to ±300 Vdc bus.
What is the difference between TM66E Modular 10–150 kVA and TM66E Compact 30–75 kVA?
TM66E Compact 30–75 kVA uses a cabinet with built-in VRLA battery modules, suitable for smaller projects where standard autonomy inside the UPS cabinet is preferred. TM66E Modular 10–150 kVA uses a shorter 19″ rack-cabinet architecture with no built-in battery modules; it is paired with an external VRLA battery system for longer runtime and wider battery-string flexibility. Both platforms use 10 / 15 / 20 / 25 / 30 kVA hot-swappable power modules. Compact 30–75 supports parallel up to 6 units; Modular 10–150 supports parallel up to 8 cabinets by configuration. Choose Compact 30–75 for built-in battery convenience; choose Modular 10–150 for external-battery runtime flexibility and capacities up to 150 kVA.
Does TM66E Modular 10–150 kVA use built-in batteries?
No. TM66E Modular 10–150 kVA uses an external VRLA battery system. This makes it better for projects that need flexible runtime, larger battery strings or separate battery cabinets. For built-in battery modules inside the UPS cabinet, use TM66E Compact Modular 30–75 kVA.
Can the TM66E Modular 10–150 kVA be paralleled for redundancy?
Yes. TM66E Modular 10–150 kVA supports direct parallel operation for capacity expansion or N+X redundancy up to 8 cabinets, subject to project design. Shared-battery parallel configuration is supported by configuration. Load Bus Synchronization (LBS) is available for dual-bus or coordinated multi-system designs. The parallel kit, including cables and configuration, is specified at order.
What battery options does the TM66E Modular 10–150 kVA support?
TM66E Modular 10–150 kVA uses an external VRLA lead-acid maintenance-free battery system with flexible string configuration. Battery strings can use 30 / 32 / 34 / 36 / 38 / 40 / 42 / 44 / 46 / 48 / 50 pcs of 12 V blocks per string, with programmable ±180 to ±300 Vdc DC bus. 36 pcs is the default configuration. Charging current is up to 18 A. Output PF depends on battery count: 36–50 pcs deliver full PF 1.0, 32–34 pcs derate to PF 0.9, and 30 pcs derates to PF 0.8. ATENCO engineers size the external-battery configuration according to UPS capacity, load level and target backup time.
Can the TM66E Modular 10–150 kVA run on a generator?
Yes. TM66E Modular 10–150 kVA supports a wide 138–485 Vac input window with Power Walk-In to reduce start-current impact on generator capacity when the generator is properly sized and configured. The UPS operates at 100% load from 305–485 Vac and derates to 40% load below 305 Vac. Input PF ≥0.99 and input THDi ≤3% help reduce upstream electrical stress.
What monitoring options does the TM66E Modular 10–150 kVA support?
TM66E Modular 10–150 kVA provides a 7-inch TFT touchscreen HMI standard, with 10-inch optional by configuration, plus history and fault logs. Communications include RS-232, RS-485, parallel, LBS, BMS and dry-contact ports. Optional intelligent-slot cards include TM550 SNMP card for network monitoring, web access, event alerts and NMS / BMS integration, plus relay-card options for dry-contact integration. Modbus RTU via RS-485 supports BMS / SCADA integration by configuration. Battery temperature sensor is optional. FW / SW online upgrade is supported in bypass mode.
What is LBS synchronization on the TM66E Modular 10–150 kVA?
LBS, or Load Bus Synchronization, is available on TM66E Modular 10–150 kVA for dual-bus or synchronized multi-system designs. It coordinates output synchronization between two independent UPS systems in applications such as dual power paths or STS-supported architectures. Availability and configuration depend on project design.
Does TM66E Modular 10–150 kVA support lithium batteries?
No. TM66E Modular 10–150 kVA uses external VRLA lead-acid maintenance-free batteries only. For lithium battery support, use TM66E Modular 40–600 kVA or TM66E Large Modular 400–1200 kVA platforms, which are factory-configured for VRLA or lithium battery systems with a 360–600 Vdc bus by project configuration.
Is TM66E Modular 10–150 kVA hot-swappable?
Yes. TM66E Modular 10–150 kVA is a modular platform with hot-swappable power modules, bypass module, monitoring module and ECU control module. Power modules can be added, removed or replaced within cabinet capacity, supporting capacity expansion and reduced-downtime maintenance by approved procedure. The battery system is external VRLA and is not the built-in hot-swappable battery-module design used on the TM66E Compact 30–75 kVA platform.
Which applications is the TM66E Modular 10–150 kVA not recommended for?
TM66E Modular 10–150 kVA, like the TM66E series, is not compatible with regenerative / energy-feedback loads, including CT machines, semiconductor cutting machines, elevators and motor-driven equipment with front-end feedback inverters, unless reviewed and approved by ATENCO engineering. It is also not the right choice when the protected load requires single-phase output; use TM11E, RM11E, TM31E or RM31E instead according to input/output architecture and capacity. For capacities above 150 kVA, use TM66E Modular 40–600 kVA or TM66E Large Modular 400–1200 kVA. For transformer-based galvanic isolation, use TM33-ET.
