ELECTRONIC VOLTAGE REGULATOR HVR-11

LINZ VOLTAGE REGULATOR HVR-11

The LINZ 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 of HVR11 LINZ Generator AVR:

- Supply voltage inlet: a) 110Vac ±15%, b) 220Vac -25%/+15%

- Maximum field current of LINZ AVR HVR11: 10 Adc

- Permanent field current of LINZ HVR11 AVR: 7 Adc

- Single phase reference voltage inlet of HVR11 LINZ 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.

In case of any necessary adjustment on the voltage value, act on the VG trimmer considering that voltage can be increased with a clockwise rotation.

It is also possible to set the voltage using a remote potentiometer of 220kΩ connecting it between terminals 6 and 8 as indicated in the electric diagram.BILITY CONTROL

The stability control acts on the dynamic response of the system avoiding the creation of oscillations on the outlet voltage value.

The LINZ Generator Voltage Regulator HVR-11 is already set in order to obtain the best performance in most applications.

In case of special application the regulator response can be set acting on ST trimmer; response timing can be increased with a clockwise rotation.
