An alternative to the Rotary Diesel UPS is the HITZINGER Clean Power unit that provides a conditioned source of supply to the consumer and provides all the benefits of a standard DRUPS whilst in stand-by operation including power factor correction, filtering of harmonics, protection against voltage peaks / drops and frequency errors.

Simplified Description – During standby operation, the alternator and KIN module act like a synchronous motor on the mains, together with the coupling choke, and provides the clean source of power.

Technical highlights

  • Network stabilisation and filtering to protect consumers from harmonic oscillations, voltage peaks, voltage drops and frequency faults.
  • U POWER systems work with voltages of up to 11 kV independently, which offers benefits such as low losses and greater reliability thanks to minimisation of components and absence of step-up transformers, among others.
  • Preventive system protection for prolonged service life, system monitoring, coil temperature monitoring, vibration monitoring, etc.
  • Reduced downtimes/maintenance intervals thanks to automatic regreasing devices, with the advantage of a completely contactless excitation device (“brushless design”) further reinforced on the alternator; tropical special coatings
  • As a general contractor, we are able to realise complete turnkey projects, including aspects such as engineering, execution planning, production with subsequent factory approval, delivery and local installation.
  • A design with an optimised level of efficiency for minimal losses in standby mode.
  • EMC-tested, long-life modular controller, 15.4-inch touchpanel with intuitive user menu navigation.

Variants and options

  • Redundancy variants (system-/controller-redundant,..)
  • Comprehensive communications interfaces (PROFIBUS, PROFINET, MODBUS, etc. )
  • Circuit breaker variants including 3-pole, 4-pole, plug-in technology,…
  • Remote maintenance access to information on the current system state via W-LAN
