The Wärtsilä JOVYSTAR PRO series is the product of advanced developmental work in the cutting-edge UPS technology sector and offers the ideal protection for critical devices. With the Wärtsilä JOVYSTAR PRO series, all controls are digitalised. With the two mutually independent microprocessors that control the rectifier, the inverter and the static bypass, we have created an essential security feature. For redundant operation (half load parallel operation, (n+1)-operation) or for a power increase, the parallel connection of up to six devices is possible.
This means your UPS system can develop in step with arising power requirements. The innovative IGBT rectifier ensures almost sinusoidal electricity consumption. The advantages of this technology are obvious: because of the improved capacity at the input of the rectifier, this UPS system consumes up to 30% less input capacity compared to conventional UPS systems with thyristor rectifier. The reduction of the current at the input of the rectifier in the network feed allows for considerable savings in the dimensioning of your distribution, the fuses and the cable. Because of their advanced technology, Wärtsilä JOVYSTAR PRO UPS systems are especially suited to an emergency power supply operation in combination with generators.
UPS systems of this series are available in the 60, 80, 100, 125 and 160 kVA capacity classes.
