The load control terminal generally has three rated voltages, namely 3 × 57.7V, 3 × 100V and 3 × 220V, according to different models. However, no related power supply device is used for setting and testing power supply for the negative control terminal, so that a 220V bare conductor direct access mode is generally adopted in the past, and the mode has two problems:

1. the requirements of terminals of different models on voltage grades cannot be met, and the damage of load control terminal equipment is easily caused by overhigh voltage;

2. the requirement of workers on safe electricity taking can not be met, the screwdriver for the 220V bare conductor is connected into the load control terminal, great potential safety hazards exist, and personal safety is easily injured.
