ZC5860 speaker reliability test system

System overview:

ZC5860 series loudspeaker reliability test system (Loudspeaker Life Test System) is a professional equipment used for speaker (or earphone) reliability test. The system has built-in stable multiple noise signal sources and digital filters, and automatically calibrates and measures the output signal; the current, voltage, impedance and power data during the test are recorded regularly through the computer, which can analyze the performance of the speaker.

Main features:

1. ZC5860 speaker reliability test system has Chinese/English operation interface.

2. Independent detection and alarm functions with 12 channels in each group and 24 channels in a single cabinet. The whole system can control the speaker reliability test of 96 channels in 4 cabinets at the same time.

3. ZC5860 has a variety of power test items, which are as follows:

◆ Rated Noise Power

◆ Rated Sinusoidal Power

◆ Long-term maximum Power

◆ Short-term maximum Power

◆ Self Stipulate On-Off test

◆Increasing Power Test

 During the "rated power" test, ZC5860 has the following functions:

1. During the test, it can automatically determine whether the speaker (or earphone) under test is disconnected. When a disconnection occurs, ZC5860 will stop the test of the channel and record the disconnection time.

2. During the test, it has the voice coil temperature rise measurement function. You can choose the table display method or the curve display method to display the temperature change of the voice coil. (Optional)

3. The ZC5860 test system has the function of power failure and recovery. During the test, if there is a power failure, the system will automatically resume operation after the mains power is restored.

ZC5860 has the following test signals:

1. Built-in multiple signal sources:

◆ White noise (White noise, 20Hz-20kHz, C.F.=2)

◆ Pink noise (Pink noise, 20Hz-20kHz, C.F.=2)

◆ IEC-60268 (C.F.=2 in line with China, Japan, Germany, Britain and other national standards)

◆ ANSI/CEA 426B (C.F.=2 conforms to American standards)

◆ Sine wave (20Hz-20kHz, logarithmic or linear sweep)

⒉ An additional programmable filter ZC6221 can be selected, and the bandwidth of the test signal can be set by yourself:

◆ A single 12-channel power amplifier. Each cabinet can be configured with 2 power amplifiers, with 24 independent output test channels.

◆ The signal output of each channel is individually controlled by the signal controller, and the measured output voltage is displayed on the PC screen.

◆ The minimum load impedance of each channel is 4 ohms (4 ohms-100 ohms).

◆ Each channel has short circuit and overload protection.

◆ When sine wave signal is output, the maximum power of each channel is 60W.

◆ When the noise signal is output, the maximum power of each channel is: 30W.

System configuration and size:

1. The system consists of a 19" standard cabinet, an external computer, and a monitor. Each PC can be connected to a maximum of 4 cabinets, for a total of 96 independent test channels.

2. Each cabinet is composed of a signal source controller (1 unit), a test controller (2 units), a digital control filter (1 unit, optional), a 12-channel power amplifier (2 units), and a test box (2 units) .

3. Cabinet size: 600mm (width) * 1600mm (height) * 800mm (depth).

4. "Zhongce Instrument Speaker Reliability Test Software System" can run under winXP or win7 operating system.
