On-line UPS JOVYSTAR PLUS 3 series

three-phasesingle-phaseredundant

UPS systems of the JOVYSTAR PLUS series are available as single-phase or three- phase systems with an output power of 10 kVA, 15 kVA or 20 kVA. The UPS systems of this type can be operated with double converter / continuous transducers technology in online mode (according to VFI-SS-111) or in standby mode in order to achieve the highest efficiency possible. For redundant operation (half-load parallel operation, n+1 operation) or for performance increase a parallel connection of up to 6 systems is feasible. ONLINE UPS SYSTEM In online mode the systems of the JOVYSTAR PLUS series ensure the optimal supply of all connected consumer loads as a stable output voltage is ensured permanently free of all standard interference pulses, overlapping currents and fluctuations. Thus critical consumers are provided with secure voltage at all times. POWER INCREASE BY CONNECTION IN PARALLEL For redundant operation (half-load parallel operation, n+1 operation) or for performance increase a parallel connection of up to six systems is easily feasible. During parallel operation active current sharing takes place. During this innovative technology based on digitisation via two 32-bit DSPs not only the effective power but also the reactive power is taken into account when controlling the load sharing. INNOVATIVE TECHNOLOGY The integrated IGBT rectifier supplies the inverter permanently with a regulated DC voltage and serves also to load the connected battery. The inverter converts the DC voltage coming either from the rectifier or from the battery into an AC voltage regulated by means of pulse width modulation. The inverter is entirely short-circuit proof.
