Self-Ballasted Lamp Load Cabinet Ensuring Reliable Switch Performance Under LED Loads

In modern lighting systems, self-ballasted LED lamps are widely used due to their high efficiency and long lifespan. However, switches controlling these LED circuits are often exposed to high inrush currents and thermal stress, which may cause contact welding, arcing, or shortened switch life.

To ensure switch reliability and compliance with IEC 60669-1 and GB/T 16915.1 standards, manufacturers need a precise and stable load testing solution.

A well-known electrical switch manufacturer required a testing system that could:
Reproduce the real-world LED load conditions specified in IEC 60669-1.
Support multi-channel testing to improve efficiency.
Provide accurate measurement of Ipeak and I²t values for performance verification.
Operate safely and stably over long test cycles.

We provided our newly developed Self-Ballasted Lamp Load Cabinet, which can be directly connected to the customer’s Switch Endurance Test Machine.

The system features:
Three independent test stations, allowing simultaneous testing of multiple switches.
Preset LED load conditions fully compliant with standard requirements.
Built-in voltage regulator (115V~125V) — no external regulator needed.
Real-time digital monitoring of voltage, power, Ipeak, and I²t values.
Dedicated metering mode with a 90° closing plate for waveform verification and calibration.
Long-on/long-off protection function with alarm safety mechanism.

After implementing the system, the customer successfully:
Reduced test preparation time by over 30%.
Improved accuracy and repeatability of inrush current measurements.
Streamlined certification testing for multiple switch models.
Enhanced testing efficiency through the three-station configuration.
The equipment operated stably under continuous long-term endurance tests and received excellent feedback from the customer’s engineering team.

The Load Cabinet for Switches Intended for Self-Ballasted Lamp Loads has become a trusted solution for switch manufacturers seeking reliable, compliant, and efficient testing of LED load performance.

Its modular design, built-in voltage regulation, and multi-station capability make it ideal for laboratories, certification centers, and R&D departments in the electrical industry.
