AHY-15 standard series AC constant current source is a steady current source with wide frequency spectrum, high precision, low harmonics and distortion. This constant current source is an AC power source that can maintain a constant output current when the external grid power supply fluctuates or the power consumption conforms to the impedance characteristics. The power supply is mainly used in products and places where specific current heating effects are applied and tested. Such as circuit breakers, fuses, thermal relays, magnetic starters, coils, etc. require experiments。



 

 

◆ Constant current, constant current adjustment range: 0-maximum continuous adjustment, constant pressure, constant voltage adjustment range: 0-maximum continuous adjustment.

◆ When using constant current and constant voltage, it can be automatically cross-converted to maintain the characteristics of both control and protection; input and output are fully isolated.

◆ 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 overcurrent test instrument.

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

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

◆ Operators must frequently adjust the voltage regulator to achieve a constant current, which is time-consuming and energy-consuming, and the accuracy cannot be compared with this power supply. In the production of low-voltage electrical appliances, the current must be verified and aging items Above, the use of this power supply is currently the best choice, such as the setting of the operating current of the thermal relay and the measurement of the thermal trip current of the air switch.

◆ It can carry out automated tests of different current levels (items: voltage, current, frequency, rise and fall time, and cycle test operations).

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

◆ RS232C/485 communication interface is standard.
