Special Combination Wave Test System

Combination Wave Test System is one of a special test machines, it can output 1.2/50μs open circuit voltage wave and 8/20μs short current wave. The test system can be used for carrying VPR Test, Surge Immunity Test and so on. The test system contends the requirements of IEC 61643. IEC 61000-4-5 and UL 1449 standards.

Application

Consumer Electronics & Home Appliances:

Used to test the immunity of power ports in devices such as TVs, refrigerators, and air conditioners against power grid surge disturbances.

LED Drivers & Lighting:

Widely applied in the LED lighting industry to prevent street lamps and indoor lighting fixtures from being damaged or burned out due to sudden voltage fluctuations.

Communication & Network Equipment:

Used to test devices such as gateways, routers, and telecom base station equipment, evaluating the protection performance of communication lines under lightning-induced overvoltage conditions.

Industrial Automation & Smart Meters:

Assesses the operational stability of core equipment such as PLC controllers, industrial computers, and smart meters in harsh electrical environments.

Standards

IEC61643.IEC61000-4-5.UL1449.IEC60060

Technical Parameters

Features

Built-in / External CDN:
Integrated or compatible coupling/decoupling networks (CDN) enable safe injection of surge pulses into single-phase or three-phase power lines as well as data and communication lines, while preventing surge feedback from damaging the power supply network.

Intelligent Control:
Equipped with a touchscreen interface, the system allows automated programming of test parameters (such as voltage, phase, polarity, and repetition rate). It can also automatically generate test reports upon completion.

Comprehensive Safety Mechanisms:
Features overload protection, emergency stop interfaces, automatic discharge functions, and safety interlock systems to ensure operator safety during high-voltage testing.

Maintenance Information

Cooling and Ventilation:

Regularly clean the fans and ventilation filter screens to prevent dust blockage, which may cause internal overheating of the equipment.

High-Voltage Cables:

Inspect high-voltage test cables for aging or damage to the insulation layer. This helps prevent high-voltage arcing and leakage current.

Fuse Replacement:

The power input terminal on the instrument panel is typically equipped with a fuse. If the device shows no response, disconnect the power supply and check whether the fuse is blown. When replacing, always use the manufacturer-specified type and rating.

Internal Maintenance Warning:

Since the test system contains high-voltage energy storage capacitors, do not open the enclosure yourself. Any internal hardware repair or safe discharge operations must be handled by qualified professional technicians.
