VARYX / VARYX PLUS static var generator (SVG) 30–200 kvar
Country: · Model: VARYX / VARYX PLUS
The VARYX static var generator covers 30–200 kvar on a 400 V network and compensates reactive power without steps, smoothly rather than in capacitor increments. Full response takes under 15 ms, so it keeps up with fast-changing loads such as welding, lifts and robotics. The VARYX PLUS version also compensates harmonics from the 3rd to the 13th.

Description
Compensation is electronic and stepless, so there is no switching of capacitor sections and no contactor wear. Rated voltage is 400 V within a permitted range of 230–450 V, at 50/60 Hz. The unit connects to a three-phase network with 3 or 4 wires. Full response time is under 15 ms, which matters where load current changes quickly, for example on welding lines or in lift drives. VARYX PLUS adds compensation of harmonics 3 to 13, so a separate filter for that range is not needed. Degree of protection IP20 means installation in a closed electrical room. For data exchange there are RS485, Ethernet and the Modbus RTU and Modbus TCP protocols, which tie the unit into a supervisory system.
How to choose
The deciding parameter is the power within 30–200 kvar, selected from the measured reactive component of the load. If the network only needs reactive power, the base VARYX is enough, and if harmonics 3–13 must be handled as well, take VARYX PLUS. When harmonics must be suppressed up to the 50th, look at VARYX FILTER at 35 A per module up to 300 A, or ACTIVEmatic FA40 at 60 A per module. Protection against voltage dips belongs to a different class of device, for example Oxygen at 200–2500 kVA.

FAQ
What is the VARYX static var generator?
It is an electronic reactive power compensator rated 30–200 kvar with no steps. It regulates smoothly, so it has no step size like a capacitor bank.
What response time does VARYX have?
Full response takes under 15 ms. That suits welding, lifts and robotics, where the load changes abruptly.
Does VARYX filter harmonics?
The base version compensates reactive power only, while VARYX PLUS also compensates harmonics from the 3rd to the 13th. For harmonics up to the 50th, VARYX FILTER is the better choice.
What voltage, protection class and interfaces does VARYX have?
Nominal 400 V within 230–450 V, 50/60 Hz, degree of protection IP20. Communication is via RS485, Ethernet and Modbus RTU/TCP.
