Product Features

Product introduction:

The AHY-12 standard series AC constant current source is a broadband current spectrum, high precision steady current, low harmonic and distortion steady current source. The constant current source is an AC power that can maintain the output current constant when the external power grid fluctuates or the electricity meets the impedance characteristics. The power supply is mainly used in products and places for the application and testing of specific current thermal effects. Such as circuit breakers, fuses, thermal relays, magnetic starters, coils and so on.


Product features:

The AC constant current source is specially designed and manufactured for low voltage electrical appliances. The output current is constant and the output waveform is pure sine wave. It can be used as an experimental instrument for detecting over current.

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

It has outstanding advantages, high precision of steady flow, and 1%, 0.8%, 0.5%, 0.3% grades according to user's usage environment. Ensure that the output current is constant. The large current generator scheme used before has been changing due to temperature changes, such as copper resistance of wires, joints and coils.

The operator must regularly adjust the voltage regulator to constant current, time consuming and energy, and the precision is not comparable to the power supply. In the production of low voltage electrical appliances, the current best choice, such as the setting of the action electric current of the thermal relay and the heat release of the air switch, is the best choice to check and age the current. Measurement and so on.

It can carry out automatic testing of different current levels (items: voltage, current, frequency, time of rise and fall, cycle test operation).

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

It can set analog (signal) control for users
