Equipment Composition
This system mainly includes five parts: high and low temperature test chamber, power supply system, load system, data monitoring system, and product communication system. Each part is designed independently and connected by a quick connector in the middle, which is convenient for maintenance and replacement. The system can test 24 products at a time, and the number can be customized according to customer needs.
Equipment Introduction
This equipment is mainly tailored for inverter products to simulate the working environment of the product, realize the high and low temperature aging test of the product after power on, and monitor and record the input and output voltage/current/power and communication in real time during the aging process. If the monitoring data is abnormal, an alarm prompt is required, which can provide accurate and reliable data support for product performance verification and quality. It is suitable for air conditioner outdoor unit panels, variable frequency compressor control panels, inverters, etc.
Equipment Features
1、The high and low temperature test chamber is divided into two parts: the constant temperature zone and the front and back of the load zone. The constant temperature zone is a multi-layer structure with heating and heat dissipation functions to ensure temperature uniformity. The load zone has forced air cooling circulation to ensure that the temperature of the load system is reasonable;
2、The temperature control system adopts PID control mode, and the multi-layer constant temperature zone has input and output and communication board connection interface;
3、The load system adopts a customized press motor to simulate the load, and uses Jinkaibo's unique simulation press technology to achieve custom switching load and verify the reliability of the PFC circuit;
4、Data monitoring: real-time voltage, current, power acquisition, real-time product communication interaction, can obtain various product states, fault conditions, abnormal conditions alarm and stop the corresponding workstation;
5、Modular design, easy maintenance, safety circuit design, one-button power-off function, high safety; 6. Monitoring data is automatically recorded and saved, and data reports are automatically exported and analyzed;
6、Support MES client selection to achieve test data and factory data interaction.
