In industrial scenarios such as low-voltage electrical appliance testing, power equipment calibration and laboratory R&D, high-precision, wide-band and intelligently adjustable AC testing equipment serves as core gear to ensure accurate test data and improve operational efficiency. Developed by Ningbo Zhimao, the AHY-15 Series Wide-Spectrum AC Constant Current Source Load Bank (Programmable Type) integrates advanced power electronics technology and intelligent control systems. It features wide-frequency output, high-precision constant current output, programmable control and multi-working-condition load simulation capabilities. Widely adopted for testing, aging and performance verification of various electrical products, it is a preferred solution in the industrial testing sector.
Boasting outstanding wide-spectrum output performance, this device covers a frequency range of 40-500 Hz, compatible with power frequency, variable frequency and other test conditions, breaking the frequency band limitations of traditional testing equipment. Whether for standard 50/60 Hz power frequency testing or product performance tests under special frequencies, the AHY-15 series delivers stable standard waveforms to meet domestic and international testing standards. Designed with pure sine wave output, it features low harmonic distortion and high waveform purity. It can fully simulate the actual power consumption environment, prevent waveform distortion from interfering with tested devices, and guarantee authentic and reliable test results.
In terms of constant current performance, the AHY-15 series achieves superior current regulation accuracy with stable current output and minor fluctuation. It supports automatic switching between constant voltage and constant current modes for steady operation. Equipped with a programmable control system and standard RS232 and RS485 communication interfaces, it enables linkage control with upper computers. Operators can preset parameters including current, frequency, operation duration and cycle times to realize automatic continuous testing. Unattended operation greatly cuts labor costs, making it ideal for integrated applications such as automated testing production lines and intelligent calibration benches. Additionally, the programmable function allows storage and one-click recall of multiple test programs, enabling quick switching of test solutions for different products and boosting the efficiency of batch testing.
As an all-in-one load bank, it can accurately simulate resistive, inductive, capacitive and other load types to replicate complex power grid load environments. It fully meets comprehensive test requirements including current tripping, aging and overload tests for low-voltage electrical appliances such as circuit breakers, AC contactors, thermal relays, transformers and air switches. The device adopts a fully isolated input and output structure, along with multiple safety protections against overcurrent, overvoltage, overtemperature and short circuit. It ensures high operational safety, effectively protecting both the equipment itself and test samples while reducing potential faults during testing.
With a robust overall structure, the unit runs quietly with high energy conversion efficiency and maintains stable performance during long-term continuous operation, suitable for round-the-clock working environments like laboratories, quality inspection institutions and production workshops. Supported by mature manufacturing techniques and strict quality control, the AHY-15 series combines practicality, stability and expandability. It can be used standalone or integrated into complete automated testing systems. With excellent overall performance, it provides solid technical support for the testing, R&D and production of electrical equipment.
