A new solution for high-frequency relay testing

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

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

A new solution for high-frequency relay testing

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 power without an amplifier, and easily achieve voltage (0~300V) and frequency (0.1Hz~ 10kHz) arbitrarily adjustable output, directly supplying power to the high-frequency relay. It not only saves equipment costs, but also avoids messy wiring and wiring in intermediate links.

PWR1000L programmable AC power supply is a high-performance, multi-function power supply device. It can not only output AC and DC power, but also has the function of voltage fluctuation and voltage harmonic simulation simulation. It provides electronic equipment for consumption, power, aviation, new energy and other fields. Normal or abnormal power input, verify its performance and reliability under various types of power input conditions. At the same time, the integrated power meter function can realize up to 99th harmonic analysis and real-time measurement of electrical parameters, providing accurate measurement data. Equipped with GUI monitoring software, which can control and monitor the programmable AC power supply, providing a diverse and simpler and faster operating experience. Programmable AC power supply is suitable for verification test in electronic product development, factory inspection and other stages. At the same time, programmable AC power supply redundancy design, with perfect protection functions (OVP/OCP/OPP/OTP, etc.), has a strong adaptability in a complex test environment.
