Usage and Adjustment

1. Switch the POWER to ON and the voltage regulator will work.
2. Adjust the plus key ∧ or minus key ∨ on panel to make the voltage on load displayed by PV reach the required value or change the set voltage value displayed on SV.
3. SCR voltage regulator uses negative voltage feedback. It is strictly forbidden to supply half-wave power to the load, so as to prevent the DC current on load from burning feedback transformer inside the instrument. In daily use, it is also necessary to prevent the unilateral conduction of the SCR.
4. Do not drive inductive loads such as induction furnaces and step-down transformers to prevent damage to the SCR.
5. If the SCR cannot be fully conducted or the output is severely jittered, it is caused by reverse connection of the trigger connection wires. Exchange the two trigger signal output wires to each other.
