AVR HVR-11 HVR11 Automatic Voltage Regulator for Diesel Generator Genset Volt Regulation
VOLTAGE REGULATOR HVR-11
The AVR HVR-11 is made with state-of-the-art electronic components which permit to obtain, with reduced dimensions, all needed functions to control any type of alternator.
Main features of this regulator are:
- Voltage static error within the limit of ±1%.
- Wide stability control regulation to guarantee the most suitable dynamic response to any situation (type of drive motor, size of alternator).
- Adjustable protection from low frequency operation.
- Adjustable protection from overexciting caused by anomalous loads.
Technical features:
Supply voltage inlet: a) 110Vac ±15%, b) 220Vac -25%/+15%
Maximum field current of : 10 Adc
Permanent field current of : 7 Adc
Single phase reference voltage inlet of Generator Voltage Regulator: 90Vac ÷ 440Vac
Outlet voltage setting of the alternator with multi-round trimmer
Stability control setting with multi-round trimmer
Intervention level setting of low frequency protection with multi-round trimmer
Intervention level setting of over-exciting protection with multi-round trimmer
Remote potentiometer inlet
Possible operation at 50Hz or 60Hz
Possible operation of alternators in parallel
For operating at 60Hz, connect regulator terminals 6 and 7 with a bridge.OLTAGE REGULATION
Voltage regulator is set during testing in order to obtain a line-to-line voltage of 400Vac/50Hz with a reference voltage of 115Vac /50Hz between terminals 5 and 6 of the regulator.
