Description
Regulation is fully electronic with no mechanical parts, so nothing in the cabinet wears out and dust does not settle on sliding contacts, as it does in servo-driven units. A short-term overload of 150 % is permitted for 4 min, which covers the starting of pumps, compressors and transformers. The accuracy of ±3 % suits sensitive medical and communication equipment. Customers include grid companies, wind farms, telecom operators and UN agencies, in particular WHO, UNICEF and the World Food Programme. The stabilizer is built in floor-standing cabinets that are installed in the technical rooms of the site.
How to choose
The power range of AVR3PS is not stated in the source data, so it is clarified for the specific load when making an enquiry. If the input mains swings wider than ±20 %, compare with AVR3AE, which has a range of ±30 %. For loads up to 2 MVA with strict loss requirements there is AVR3AN with an efficiency above 98 %, and for sites of 18–190 kVA in city networks AVR3x is enough.

FAQ
What output voltage accuracy does AVR3PS have?
The output voltage is held to within ±3 % with input fluctuations of up to ±20 %.
For how long does AVR3PS withstand an overload?
An overload of 150 % is permitted for 4 min, which is enough for starting motors.
How does Pro Series Plus differ from Pro Series?
AVR3PS is aimed at remote and dusty sites and gives an accuracy of ±3 % at ±20 % input, whereas AVR3AS at the same range has an accuracy of 3–4 %.
Does AVR3PS work in dusty rooms?
Yes, the design with no moving parts is resistant to dust and harsh conditions, so the stabilizer is installed at remote sites.
Who uses AVR3PS stabilizers?
Grid companies, wind farms, telecom operators and UN agencies, in particular WHO, UNICEF and WFP.
