What is the control power supply of XLS series high-vacuum angle valves?
-
The control power supply of XLS series valves is a method of suppressing the temperature rise of the coil by applying a starting voltage at start-up to operate the product and then holding it at a low voltage.
When the type without a control power supply is selected, the user needs to control the power supply themselves.
It is necessary to control switching to a holding voltage of 25% of the starting voltage after the starting voltage is first energized for 0.15 to 0.2 s. Do not apply the starting voltage for more than 0.3 s. Heating the coil may burn it out.
Please check the figure below. If the product is equipped with a control power supply, this control power supply circuit is provided.
If the operating power supply voltage is energized while the valve is open, it is acceptable not to drop it to the holding voltage.
