CHARACTERISTICS

The True On-Line Double Conversion technology ensures excellent output voltage parameters regardless of the power disturbances and the type of receivers being powered.
The modular structure provides the possibility of easy expansion of power and replacement of the "hot" power modules in the HotSwap technology. Scalability of power with a step of 30kVA / 30kW in the range of 30 - 120kVA.
3-level IGBT rectifier - the most advanced technology ensuring very low THDi and high power factor as well as processing efficiency.
Automatic bypass - uninterruptible ensures uninterrupted power supply to critical loads such as overheating or failure.
Service bypass - allows servicing of devices without switching off powered receivers. Separate power supply Bypass track provides the ability to provide a reserve power source for receivers even in the event of a device failure or UPS protection in the main track.
Communication interfaces: RS232, RS485, MODBUS for monitoring and managing the operation of the power supply and receivers,
DryContact relay contacts for cooperation with BMS systems
SNMP integration with NMS network management systems,
Remote switch connector A. Fire (REPO) to ensure remote disconnection of power supply to receivers in the event of a fire,
A.Fire. Switch (EPO) on the control panel enables immediate disconnection of power from the receivers,
Control and monitoring panel LCD (touch) gives the opportunity to diagnose parameters and operation mode of the power supply, enables the registration of events and, among others, graphical preview of current and voltage waveforms.
Small dimensions, thanks to which a large space for installing the device is not required.
The high efficiency of the device (> 96%) reduces energy consumption and limits the heat emitted, making possible cooling of rooms easier and cheaper.
The ECO-Mode mode allows a significant reduction of the unit's operating costs and virtually eliminates heat emission.

Automatic diagnostics and fully digital control (32 bit DSP x2) guarantee full device efficiency, control of components and operating parameters without the need for user intervention.
The high value of the input power factor 0.99 limits the value of the current consumed by the device from the network.
The high value of the output power factor of 1.0 allows for supplying a wide range of receivers.
The wide range of input voltage in the normal operation mode ensures stable operation of the device without the need to use the battery, which significantly affects the extension of their service life.
A wide range of input frequencies in the normal operation mode allows free use of the power supply in a network with unstable parameters and when powered from a power generator.
Simple to use - easy to connect to the network and simple switching on and off the device does not require special qualifications from the user.
Advanced battery management ensures optimal charging and use of battery, increases their lifespan and lowers operating costs. Temperature compensation function of the charging voltage.
Excellent quality of the output voltage, achieved thanks to the use of a 3-level IGBT inverter using highly advanced PWM control technology, ensures that voltage is supplied with stable parameters, regardless of the power disturbances and the type of powered equipment.
High overload protection ensures device protection and continuity of power supply in the presence of transient transients.
Advanced software that allows the user full control over the device and powered receivers.
Configurable work parameters - nominal voltages, frequencies, preferred modes of operation, communication method - significantly broadens the range of possible applications.
Redundant configurations:
- redundant work for increased reliability
- capacitive parallel operation for increased power
- HotStandby work
- double-track work
