1. The transformer adopts a vertical structure and combines pins with screws to fix it
2. It will be connected to the base, so the tolerance needs to be very small for dimensional coordination.
3. Use insulating protective cover to increase its resistence to stress
4. There is thermal fuse installed inside the transformer


1. Sturdy structure prevents it from damage
2. Precise dimensional coordination makes it easy to install
3. Can be installed firmly and sturdily, good performance in anti-vibration and shock resistance
4. The transformer is equiped with its own thermal fuse to protect the circuit to reach high safety
