Front internal access
The KEOR HPE UPS was designed to be installed and maintained from the front. All protection switches and communication ports are located at the front of the UPS. An internal door provides access to parts installed at the bottom of the UPS and allows assemblies and components to be accessed from the front. This design means that all parts are easily accessible for maintenance, significantly reducing the MTTR (mean time to repair) and service times.
Parallel capacity
Up to 6 units can be connected in parallel, to achieve a maximum 3MW of uninterrupted power. The UPS system provides stable and reliable parallel operation even at high power ratings using several UPS modules (more than 3) due to dedicated power line balancing systems.
Redundancy
The KEOR HPE system allows for up to 6 UPS systems to be operated in parallel to maximise server continuity and system safety.
Back Feed Detection
All KEOR HPE UPS have contacts to activate voltage back feed protection.
Insulation Transformers
Available for the entire Keor HPE range as optional external accessories.
Optimal Battery Management
The KEOR HPE UPS system includes advanced battery charging and management functions, to guarantee the best performance and optimum operating life.
- Intermittent Charing: the UPS has intermittent charging with adjustable cycles (27-3 standard), to extend the effective operating life and achieve maximum energy savings
- Automatic Current Charging: regulation with load power priority, to quickly charge batteries for long autonomies
- Voltage Charge: compensation according to temperature, to avoid excessive charges and overheating – a temperature probe is included in each unit
