AHY-15 STANDARD SERIES AC CONSTANT CURRENT SOURCE

Series:

The AHY-15 standard series AC constant current source is a wide-spectrum, high-precision, low-harmonic, low-distortion constant current source. This constant current source is an AC power supply that can maintain a constant output current even when the external power grid fluctuates or the impedance characteristics of the load change. This power supply is mainly used in products and places where specific current thermal effects are applied and tested. For example, experiments on circuit breakers, fuses, thermal relays, magnetic starters, coils, etc.

Product Features

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

◆ When using constant current and constant voltage, it can automatically switch between them, maintaining both control and protection characteristics; input and output are fully isolated.

◆ The AC constant current source is specially designed and manufactured for low-voltage electrical appliance users. Its output current is constant, and the output waveform is a pure sine wave. It can be used as a test instrument for overcurrent experiments.

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

◆ Outstanding advantages: high current stability accuracy. Accuracy levels of 1%, 0.8%, 0.5%, and 0.3% are available depending on the user's environment. Ensures constant output current. Previously used high-current generator solutions had fluctuating copper resistance in wires, connectors, and coils due to temperature changes.

◆ Operators frequently had to adjust the voltage regulator to maintain a constant current, which was time-consuming and laborious, and the accuracy could not compare to this power supply. In low-voltage electrical appliance production, for projects requiring current calibration and aging, this power supply is currently the best choice, such as setting the operating current of thermal relays and measuring the thermal trip current of air circuit breakers.

◆ Automated testing of different current levels can be performed (items: voltage, current, frequency, rise/fall time; cyclical testing operation is possible).

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

◆ RS232C/485 communication interface is standard.

Product Applications

AC air circuit breakers / AC contactors / mechanical switches / electronic switches / AC current transformers / thermal relays / molded case circuit breakers / miniature short-circuit devices and those requiring rated current setting

Operating current / short-circuit protection current, etc. / automated testing and calibration platforms / current requirement testing locations
