PRODUCT OVERVIEW

Eaton 93T40KMBSB High‑Capacity Online UPS

The Eaton 93T40KMBSB is a robust 40 kVA / 40 kW three‑phase online/double‑conversion UPS engineered to protect critical industrial, data centre, and commercial electrical loads from mains disturbances, power surges, and outages. Designed as a free‑standing tower unit, it features an internal maintenance bypass switch (MBS) that enables safe servicing without interrupting protected loads. The UPS supports parallel configurations for capacity and redundancy, making it suitable for scalable high‑availability power systems.

Electrical Input and Output Performance

Operating with three‑phase input and three‑phase output, the Eaton 93T40KMBSB delivers 40 kVA of apparent power at a unity power factor (1.0), maximizing real‑power utilization for balanced loads. Output voltage is configurable between 380 V and 415 V, and the system maintains low total harmonic distortion under linear load (≤ 2 %). It supports programmable output frequency (50/60 Hz) and fixed hardwired connections for both input and output, providing resilient, grid‑independent power conditioning.

Battery and Runtime Configuration

The Eaton 93T30KMBSB does not include internal batteries by default; instead, it is designed for systems that integrate external battery cabinets or external battery modules via hardwired connections. This modular approach allows end users to tailor runtime to specific load and redundancy requirements. Although user‑replaceable internal battery modules are not included, the UPS features start‑on‑battery capability to support critical starts when utility power is absent.

3. Battery System and Runtime Capabilities

This model does not include internal batteries by default; instead, it provides space and hardwired connections for external battery cabinets or battery kits, allowing customers to tailor runtime to specific load and availability requirements. The UPS supports start‑on‑battery capability, enabling operation directly from the battery system when mains power is unavailable. Eaton’s Advanced Battery Management (ABM) charging technology ensures efficient battery charging and management when external batteries are installed.

4. Communications, Controls, and Efficiency

The 93T40KMBSB includes a touchscreen human‑machine interface (HMI) for local monitoring and diagnostics, alongside space for two communication expansion cards that support remote management, alarms, and integration with network management systems. Potential‑free switch contacts are provided for integration with external control systems or building management systems. In Improved Efficiency (ESS/Eco‑mode) operation, the UPS can achieve up to 99 % energy efficiency, reducing operating costs and thermal load in large installations.

5. Mechanical, Environmental, and Compliance Details

The Eaton 93T40KMBSB’s chassis measures approximately 1575 mm (height) × 380 mm (width) × 740 mm (depth) and weighs about 169 kg, reflecting its industrial‑grade build. The tower‑form factor is tailored for facility and data environments where robust standalone units are practical. The UPS carries international safety and EMC certifications including IEC/EN 62040‑1, IEC/EN 62040‑2, and EN 62040‑3, and is CE marked and RoHS compliant, ensuring compliance with global standards. It also supports parallel operation of up to four units for expanded capacity and redundancy.
