1. The AC constant current source is specially designed and manufactured for users of low-voltage electrical appliances. Its output current is constant, and the output waveform is pure sine wave, which can be used as an experimental instrument for detecting overcurrent.

2. This AC constant current source can carry resistive, inductive and capacitive loads to meet the requirements of low-voltage electrical appliances for testing power.

3. Outstanding advantages, high accuracy of steady flow, can be 1%, 0.8%, 0.5%, 0.3% according to the user's environment. Ensure that the output current is constant. The high current generator scheme used before has been changing due to temperature changes, and the copper resistance of wires, joints and coils has been changing.

4. The operator must often adjust the voltage regulator to maintain a constant current, which is time-consuming and labor-intensive, and the accuracy cannot be compared with this power supply. In the production of low-voltage electrical appliances, the current must be verified and aged. The best choice at present, such as the setting of the thermal relay operating current, the measurement of the thermal tripping current of the air switch, etc.

5. Can carry out automated tests of different current levels (items: voltage, current, frequency, rise and fall time, cycle test operation)

6. Frequency adjustable range: 40-500HZ (optional), fixed output: 50HZ, 60HZ (fixed output frequency in more ranges can be designed according to user needs)

7. The analog quantity (signal) control can be set for the user
