AHY-22L series low-power AC constant current source/current source (formerly AHY-10L) is a steady current source with wide frequency spectrum, high precision, low harmonics and distortion. The constant current source is an AC power source that can keep the output current constant when the external grid power source 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 and other experiments。
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 a 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 testing power supplies. It has outstanding advantages: the accuracy can reach 0.2% (two thousandths) to ensure a constant output current. Communication can provide communication control software and communication protocol, which is convenient for users to realize automatic control. The minimum control accuracy is 1mA and the accuracy can reach ±0.1%. The large current generator scheme used before is due to temperature changes, and the copper of the wires, joints and coils The resistance is constantly changing. The operator 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. The use of this power supply is currently the best choice, such as the setting of the operating current of the thermal relay, the measurement of the thermal trip current of the air switch, and so on。
