The DC transformer for the rail has overload protection, which is activated when the load exceeds 110% to 150% of its rated capacity. This protects the power supply from damage. Additionally, there is over-voltage protection in place, triggered when the voltage exceeds 110% to 140% of the rated voltage, which safeguards the end device. To prevent electrical equipment at the output from being short-circuited, there is short-circuit protection that eliminates the safety hazard at the source. Furthermore, high power products with 200W and 350W have over-temperature protection, making them ideal for industrial use.
