Electronic Design - New test scheme of high frequency relay

Relays are widely used in various fields, such as electric vehicles, smart meters, electrochemistry, etc. their performance and reliability also affect the stability of equipment system. Then relay test and verification standards are becoming more and more strict, and the comprehensive requirements of test equipment are higher.

Relays are widely

Relay is an automatic switching element with isolation function. It is widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment. It is one of the important control elements. For high-frequency relays with power consumption of more than 100W and operating frequency of less than 10kHz, 1K ~ 10kHz AC is usually required during verification test. In the past, high-frequency AC is generally output through the combination of signal generator and power amplifier, that is, the signal generator generates low-energy high-frequency AC, which is amplified by the gain of power amplifier to achieve high-energy high-frequency AC in line with practical application.

At present, pwr1000l programmable AC power supply (output voltage 0 ~ 300V, output frequency 0.1Hz ~ 10kHz, power up to 1000W) can directly output high-energy high-frequency AC without amplifier, easily realize arbitrary adjustable output of voltage (0 ~ 300V) and frequency (0.1Hz ~ 10kHz), and directly supply power to high-frequency relay. It not only saves the equipment cost, but also avoids the messy wiring in the intermediate link.

Pwr1000l programmable AC power supply is a high-performance multifunctional power supply equipment, which can not only output AC and DC, but also have the function of voltage fluctuation and voltage harmonic simulation, so as to provide normal or abnormal power input for electronic equipment in the fields of consumption, electric power, aviation, new energy and so on, Verify its performance and reliability under various types of power input conditions. At the same time, it integrates the function of success rate meter, which can realize up to 99th harmonic analysis and real-time measurement of electrical parameters, and provide accurate measurement data. Equipped with GUI monitoring software, it can control and monitor the programmable AC power supply, providing diversified, simpler and faster operation experience. Programmable AC power supply is suitable for verification and testing in the stages of electronic product R & D, and delivery inspection. At the same time, the programmable AC power redundancy design has perfect protection functions (OVP / OCP / OPP / OTP, etc.), and has strong adaptability in complex test environment.
