Ring Wave Generator

The RWG61000-12 series Ring Wave Generator | Ring Wave Simulator is used to simulate ring wave interference encountered by electronic and electrical products (EUT) in real-world such as damped oscillation pulses generated by high-voltage switching, transformer winding transients, and power system faults. Through standardized testing, the generator assesses the equipment under test’s (EUT) tolerance to such interference, promptly identifying insulation weaknesses and circuit immunity defects, ensuring stable operation in complex power environments.

The RWG61000-12 series Ring Wave Simulator equipped with a large Android touchscreen display with English and Chinese support, it is widely used for EMC compliance testing in a variety of fields including LED lighting, medical, power, industrial control, new energy charging stations, small and medium-sized motors, low-voltage electrical equipment, energy meters and household appliances.

Applications:
1. Industrial Control and Power Equipment
• Industrial Control Equipment Testing: For devices such as PLCs (Programmable Logic Controllers), inverters, servo drives, and industrial routers, the built-in CDN is used to test power lines, simulating ringing wave interference generated by high-voltage motor startup and shutdown and transformer switching in factory workshops. This verifies whether the equipment experiences control command delays and data transmission errors, ensuring stable production line operation.
• Power Equipment Verification: Testing power terminal equipment such as distribution boxes, meters, and relay protection devices. The RWG61000-12A is used to simulate high-amplitude ringing waves generated by power system faults. This allows the device to be evaluated for insulation performance and circuit interference immunity, preventing equipment malfunction or burnout due to interference and ensuring power grid safety.

2 New Energy and Automotive Electronics
• New Energy Charging Pile Testing: Testing the power input ports and charging communication ports (CAN bus) of AC and DC fast charging piles. By injecting clamp-coupled ringing waves, this simulates interference from grid fluctuations or internal switching in the charging piles. This verifies whether the charging piles experience charging interruptions or communication failures, and whether they comply with EMC requirements for new energy vehicle charging systems.
• In-Vehicle Electronic Component Testing: Testing components such as the onboard BMS (battery management system), onboard charger (OBC), and in-vehicle navigation. This simulates ringing wave interference generated by the vehicle’s power supply system (e.g., generator and high-voltage distribution box) to ensure stable operation of the components while driving and without compromising driving safety.

3. Consumer Electronics and Home Appliances
• Home Appliance Testing: For high-power appliances such as refrigerators, washing machines, air conditioners, and microwave ovens, the built-in CDN is used to test power cords, simulating ringing wave interference generated by air conditioner startup and shutdown, and refrigerator compressor switching, in the home power grid. This verifies whether the appliances experience freezes or malfunctions.
• Digital Product Testing: For digital accessories such as mobile phone chargers, laptop power adapters, and smart sockets, the power port’s tolerance to low-amplitude ringing waves is tested to prevent interference that could reduce charging efficiency or damage accessories, thereby ensuring a safe user experience.

4. Medical Electronics
• Medical Equipment Interference Immunity Testing: Based on medical industry EMC standards, power cords and signal cables (such as blood oxygen sensors and ECG electrodes) of medical devices such as monitors, ultrasound diagnostic equipment, and infusion pumps are tested. This simulates the ringing wave interference generated by the operation of large medical equipment (such as CT and MRI) in hospital power grids, ensuring that the equipment does not experience data acquisition errors or false function triggering, thus ensuring patient safety.
