Adjusters
1. Explanation:
AN-5-203 Automatic voltage regulator (referred to as Automatic Voltage Regulator) is a seal-type electronic device that is designed for supporting electric friends generators. Automatic Voltage Regulator has controlled automatic adjustment of generator output voltage by controlling the control of the motivation of the generator.
2. Technical parameters:
Fighting and auxiliary winding input: AC 55V-220V;
The highest excitation voltage input: 120V/5ADC/10s;
Entrusted by the main winding voltage input: 400VAC, 50Hz/60Hz:
Low frequency protection 50/60Hz can be adjusted;
The magnetic field resistance of the generator> 5Q;
The adjustment rate of the voltage voltage soil 0.5%;
The voltage adjustment range> 15%;
Minimum remaining magnetic encouragement voltage> 5V/30Hz;
The voltage of the voltage at 1kq/1W of the external power level is 12%of the voltage.
3. Precautions for use:
The installation, connection, and inspection operations must be implemented by professionals with professional knowledge, and the regulator is installed in a generator or a place where others are easy to touch. In the running state, do not touch the regulator to avoid dangerous accidents.
4.1 Adjustment:
The "U/F" potentiometer is to set the frequency of low -frequency protection. At 50Hz, low -frequency protection generally sets 46Hz, and at 60Hz 120 (set 56Hz). Establish voltage, adjust the police to transfer to the low frequency value required, slowly adjust the "U/F" potentiometer counterclockwise to start dropping the generator voltage. It means that the frequency is insufficient. Under this situation, the output voltage of the generator will decrease due to low -frequency protection movements to prevent low -frequency excessive damage to the magnetic field stator coil. When used at 60Hz, re -adjust the "U/F" potentiometer to the required low -frequency protection va
