Sample Power Supply (Optional)

1、DC12V24V36V20A power supply

2、Reserve electrifiable interface terminals, configured by customers. 

3、Dust-proof socket is installed in the chamber. The power supply is AC220V20A, which is controlled by programmable timer.

Sample Vacuum Device (optional) 

The air pressure in the test chamber is lower than the outside, and a vacuum pump device is required for the test sample (IP5/IP6 test)

The air pressure in the chamber is the same as the outside. No vacuum pump device is required.

Power Supply and Conditions

AC220V single phase; voltage allowable fluctuation range is 5%; frequency allowable fluctuation range is 50/60HZ; protective grounding resistance is less than 4Ω, requiring the user to equip the device with the corresponding capacity of air or fuse-free switch at the installation site, and this switch must be independently controlled, when the equipment is used to place the power sample in the box. Please use the external power supply for the sample power supply, and do not use the power directly.
