How to operate the high and low voltage switchgear power tester
1. Function: Used for high and low voltage switchgear power test, can provide a variety of AC and DC power supply.
2. Input voltage: three-phase four-wire AC380V / 50Hz
3. Output voltage and current:
a) Continuous output current output 0-500A
b) DC fixed voltage output DC24V, DC110V, DC220V (5A)
c) DC voltage output DC 0-250V (10A, adjustable value)
AC voltage output AC 0-250V (5A adjustable value)
d) Three-phase AC 0-10A output (12V adjustable value)
e) Three-phase AC 0~750V output (5A adjustable value)
f) Three-phase AC 100V output (5A fixed value)
g) Three-phase AC 380V output (32A fixed value)
h) Large current output 0-500A continuously adjustable
i) Three-phase adjustable voltage (AC 0~750V) output circuit setting selection switch, selectable function: over setting
Voltage, start the power-on timing function, when the voltage and low pressure set value, the timing function returns automatically. Voltage relay selection
Choose static products.
4. The universal test bench is equipped with a universal wheel that can be moved, requiring beautiful appearance and flexible movement.
5. Integrated test station configuration terminal and external cable.
a) Continuous output current output 0~500A (see panel a)
0～500A indicator: Display 0-500A current value (Table 1)
0~500A sub-button: disconnect current regulation power
0 ~ 500A button: start the current adjustment power supply, clockwise rotation regulator (Table 1) shows 0 ~ 500A current value;
b) DC fixed voltage output DC24V, DC110V, DC220V (5A) (see panel b box)
DC fixed work indicator: When DC fixed output control is on, this light is on;
DC output selection: When the knob points to 24V or 110V or 220V, the output is DC 24V or 110V or 220V;
DC fixed output control: When the DC fixed output control wants to point to “closeâ€, the indicator light is bright, that is, there is 24V or 110V or 220V output;
When the DC fixed output control wants to point to “minuteâ€, the indicator light goes out, ie no 24V or 110V or 220V output;
c) DC voltage output DC 0-250V (10A, adjustable value) (see panel c box)
Function selection: rotate the knob to select DC 0-250V voltage;
0-250V button: power on, clockwise rotation regulator, DC0-250V output (Table 3 shows the DC voltage value);
0-250V sub-button: disconnect power, stop working;
d) Three-phase AC 0-10A output (12V adjustable value) (see box d)
AC 0-10A button: turn on the three-phase voltage, turn the voltage regulator clockwise, there is a three-phase AC 0-10A output (Table IV shows the three-phase current value);
AC 380V sub-button: disconnect the three-phase voltage, stop working;
e) Three-phase AC 0~750V output (5A adjustable value) (see box e)
Voltage monitoring knob: Turn the knob (Table 5) to display the voltage of one of the three phases;
AC 750V button: turn on the three-phase voltage, turn the regulator clockwise, there is a three-phase AC 750V output;
AC 750V sub-button: disconnect the three-phase voltage, no three-phase AC 750V output;
Pressure resistance time relay: Arbitrarily set the withstand voltage time;
Realization function: three-phase adjustable voltage (AC 0~750V) output circuit setting selection switch, choice can be realized
Function: Exceeding the set voltage, start the power-on timer function, when the voltage and low voltage set value, the timer function automatically
return. Voltage relays select static products.
f) Three-phase AC 100V output (5A fixed value) (see panel f box)
Voltage monitoring knob: Turn the knob (Table 6) to display the voltage of one of the three phases;
AC 100V button: three-phase voltage, three-phase AC 100V output;
AC 100V sub-button: disconnect the three-phase voltage, no three-phase AC 100V output;
g) Three-phase AC 380V output (32A fixed value) (see panel g box)
AC 380V button: three-phase voltage, three-phase AC 380V output;
AC 380V sub-button: disconnect the three-phase voltage, no three-phase AC 380V output;
