Attention: Dear friends, as the holiday approaches, friends who have not yet placed orders can do so as soon as possible. We will arrange delivery for you as soon as possible. We will not deliver between January 22 and February 6, 2025, but you can place an order and wait. It will be shipped after the holiday, so friends who have not placed an order yet should do so as soon as possible.

1.DST-51-DFKV automatic voltage regulator (AVR for short) is a partially sealedelectronic device, specially designed for Designed for maha generators. AVRrealizes the automatic output voltage of the generator by controlling theexcitation current of the generator magnetizer Adjust.

2. Voltage adjustment (VOLT)

Before starting up, the voltage setting potentiometer can be adjusted counterclockwise (the factory has been set to 400V), and the external potentiometer port is short-circuited. When the generator set runs normally and reaches the rated speed, the potentiometer is adjusted clockwise and the voltage rises, and vice versa. Decrease until the output voltage meets the requirements.

If you need to adjust the external voltage, you can disconnect the external potentiometer port connection line on the AVR and connect a potentiometer. Because the external port of the AVR is live, if you want to install an externally controlled voltage trimming potentiometer, the potentiometer must be To ensure good insulation, it is recommended to use an all-plastic multi-turn potentiometer. If a metal shell potentiometer is used, its shell must be grounded!

3. Stability adjustment (STAB)

Adjusting the "STAB" potentiometer can stabilize the output voltage of the generator, but excessive adjustment will increase the instantaneous voltage fluctuation rate of the generator under heavy load. It is recommended to run the generator with no load, check whether the speed is correct and stable, turn the "STAB" potentiometer fully counterclockwise, and then slowly rotate clockwise until the generator voltage starts to fluctuate. The correct setting is to rotate slightly counterclockwise from this position (that is, the voltage is stable at this point, but it should be very close to the unstable zone)

4. Excitation:

When the residual magnetization voltage of the generator is insufficient to make the AVR build up the voltage, it must be excited from the outside. After the engine starts running, use a 12V battery. The negative pole of the battery is connected to F- of the AVR, and the positive pole of the battery is connected through a (5A) diode. The F+ of the AVR stops the excitation when the generator voltage is established at 20%. Very important: a diode must be used to ensure that the AVR is not damaged!

5. Adjust(U / F)

5.1 Low frequency protection adjustment (U / F)

"U / F" potentiometer is for setting low frequency protection

Frequency inflection point value, when used at 50Hz, low frequency protection U%

-Generally set at 45Hz, when used at 60Hz (set

U / F characteristic curve 55Hz), its setting steps: make the engine start and power on 120

Pressure build, adjust the engine to the required low frequency value,

Slowly adjust the U / F potentiometer counterclockwise to make the generator 100 The voltage starts to drop, the protection action is as shown in the figure below,
