ZC5820 speaker life tester

As an upgraded model of the original ZC1681 series, the ZC5820 multi-channel speaker life tester has changed the original MCU control to an industrial computer, providing a basis for realizing instant communication, remote control and other intelligent operations. This is a multi-channel, multi-function power test equipment. The user can store the test signal in the computer and play it through a professional sound card, and its stability is greatly improved; the parameters of the signal after power amplification are guaranteed to be consistent with the original signal. Each output has a separate measurement system, which can measure the actual voltage, current, DC resistance, temperature rise, product status and other data of each channel. The biggest highlight of this product is the data storage and processing, as well as the visual graphical interface, which can display the current status more conveniently and intuitively, save all the data, and facilitate the analysis of the product after the test.

Brief introduction

As an upgraded model of the original ZC1681 series, the ZC5820 multi-channel speaker life tester has changed the original MCU control to an industrial computer, providing a basis for realizing instant communication, remote control and other intelligent operations. This is a multi-channel, multi-function power test equipment. The user can store the test signal in the computer and play it through a professional sound card, and its stability is greatly improved; the parameters of the signal after power amplification are guaranteed to be consistent with the original signal. Each output has a separate measurement system, which can measure the actual voltage, current, DC resistance, temperature rise, product status and other data of each channel. The biggest highlight of this product is the data storage and processing, as well as the visual graphical interface, which can display the current status more conveniently and intuitively, save all the data, and facilitate the analysis of the product after the test.

Scope of application

Mobile phone speakers, receivers, MP3, tablet computers, laptop speakers, low-power TV speakers, etc.

Performance characteristics

  • Signal source: built-in sine wave generator and frequency sweep controller, can be stored in various formats of audio files
  • Two sets of voltages can be arbitrarily set up to 20 channels at the same time to monitor, automatically record and display voltage/current/DCR/temperature rise/test time and status
  • The test voltage is automatically corrected, the accuracy can reach ≤1%, and the display is 0.001V
  • 8-inch LCD panel, richer display content, larger fonts, easy to observe
  • Interface: front panel signal data input interface (USB), rear panel USB, LAN network port
  • Temperature rise measurement range: 0~200℃, measurement accuracy ≤5%±1℃
  • Support multiple working modes: continuous, intermittent, and debugging. Among them, the minimum interval supports 0.5s, and the voltage can still be accurately measured
