For single-phase stabilized power supplies below 1.5KVA, use fuses for overload or short-circuit protection. For single-phase above 2KVA and three-phase stabilized power supplies, use circuit breakers for overload or short-circuit protection.
Before use, check that the voltage of the power grid should be within the allowable input voltage range of the machine, and then connect the machine according to the phase and neutral mark of the machine, and then connect the machine to the power grid after connecting to the ground.
Turn on the power switch, the "work indicator" light of the stabilized power supply is on, indicating that the stabilized power supply is working normally, and the output voltage meter on the panel should indicate 220V.
Turn on the power switch of the electrical equipment. In the event of a grid failure or excessive output voltage, the electrical equipment used is not working properly, the stabilized power supply and the power switch of the electrical equipment should be turned off in time.
If necessary, the user can adjust the output voltage, control the variable potentiometer on the circuit board to turn clockwise, the output voltage rises, and turn counterclockwise to reduce the output voltage.
Since the single-phase 2KVA~10KVA uses terminal blocks for wiring, please follow the wiring instructions to remove the lower screw wiring, and remember not to move the upper screw. The input and output wires should use a single copper wire, and tighten the screws as much as possible to prevent heat generation at the connection.
Electronic Voltage Regulator: AC Automatic Voltage Regulator
Single-phase voltage stabilizers above 10KVA and three-phase voltage stabilizers generally use terminal connection. If the connection is loose, it must be tightened; first connect the output wire, then the input wire, and then power on.
Delay function use: short delay 3~8 seconds, long delay 4~8 seconds to start work, if the main switch button can not start the regulator, please select short delay start work, because the long delay takes more than 4 minutes The control contactor can be activated.
Loss-phase protection function: Open-phase protection switch means that the three-phase loss does not start; loss-phase protection is off, means no protection status. If there is an input voltage output voltage button, just select according to the instructions. Three-phase with input and output voltage buttons, pressing and not pressing respectively indicate that the AB and AC phase voltage should be 380V.
