ZC1681B-S480 Simple Multi-channel Loudspeaker Life Test System
Brief introduction
The ZC1681B-S480 speaker life tester is a multi-channel product of the ZC1681 series. It is a simple and easy-to-operate product designed for short-term verification before the product is shipped.
Basic skills
- Maximum number of access channels: 480 channels, test parameters: sine, SD card player.
- Aging test time: 0.1~9999 hours can be set arbitrarily.
- Fault warning: The 480 LEDs on the panel display the location of the faulty channel and the cause of the fault at the same time.
- Man-machine interface: 7-inch true-color LCD screen display, touch screen + keys for quick input.
New functions and features
- There are many channels, simple operation, 480 channels can be started at the same time, open circuit, short circuit judgment and indicator light display.
- The test signal is complete, built-in sine wave fixed frequency/sweep frequency, SD player can meet the requirements of speaker life test under different reference standards.
- Modular structure design, contains 5 units, each unit has 6 modules, and each module contains 16 parallel Class D power amplifiers. Each power amplifier is independent of each other, which is convenient for maintenance and fault detection.
