Electronic voltage regulator controls corrosion tank vibration speed
01 Corrosion vibration tank
I. Introduction
This is an electronic AC voltage regulator that just arrived this morning. It uses a thyristor to control the output AC voltage. For resistive and inductive loads, its control effect is very good. But for electronic energy-saving lamps, it cannot control its output power. Next, we will modify it to control the shaking speed of the corrosion tank that corrodes the circuit board. It is driven by a handheld chainsaw and is a motor load.
2. Put it into a plastic box
In order to prevent the electronic voltage regulator from being corroded by the acidic gases in the corrosion tank, it is to be installed in a sealable plastic box. The volume of this box can almost accommodate the electronic voltage regulating module. You need to open a hole on one side of the plastic box, remove the knob of the electronic voltage regulating module, and fix it in the hole on one side of the plastic box. This is the final installation situation. Afterwards, plastic tape needs to be used for auxiliary sealing of the lead output holes. Field testing will be carried out below.
This is the etching tank used to corrode circuit boards, and it can be moved quickly from side to side with the help of a hand-held electric saw. To control the swing speed, an external transformer is used to vary the speed of the chainsaw. The original autotransformer used has been corroded after three years. Now it has been replaced with a fixed transformer. However, its output voltage is a bit small and the corrosion tank shakes a bit slowly. Next, we use this electronic voltage regulator installed in a plastic box. The device is used to control the shaking speed of the corrosion tank.
After the power-on test, it can be seen that the speed of the handheld electric saw can indeed be controlled. This wire outlet needs to be sealed with tape at the back. After replacement, everything works fine.
※ Summary ※
This article records the use of an electronic thyristor voltage regulator to control the speed of a hand saw. Under motor load, this electronic voltage regulator can output 1000W of power. A handheld chainsaw is used to drive this circuit board corrosion groove from side to side.
