Dustproof test box | waterproof and dustproof test box | sand and dust test box

Product Usage:
Dust test chambers are used for low-voltage electrical appliances, motors, instruments, meters, lighting fixtures, household appliances, and other products. They are often affected by sand and dust environments during storage, transportation, and use. The equipment uses artificial simulation of sand and dust environments to test the dust resistance of the test samples. Dust test chambers are used for LED lighting fixtures, low-voltage electrical appliances, motors, instruments, household appliances, and other products, and are often affected by sand and dust environments during storage, transportation, and use. Especially for automobiles and electrical appliances, the impact of sand and dust is more significant. This dust test chamber cannot meet the sand and dust tests with wind sources in GB2423 and GJB150

Product features:
The dust-proof test chamber can provide a non laminar vertical circulation airflow for dust carrying, and can control the circulation of dust carrying airflow, start, stop, automatic timing or continuous control. It can be used for various performance tests such as dust blowing, dust reduction, temperature, etc., making it an ideal dust-proof test equipment.

Introduction to the Control System of Dust Prevention Test Chamber:
The programmable controller of the sand and dust testing machine can individually or collectively control the blowing fan, dust vibration, and total testing time. The maximum test time is 99 hours and 59 minutes. Adjustable wind speed inside the box (automatically adjusted through a frequency converter) and functions of the main components of the sand and dust testing machine

1. The main controller of the equipment adopts imported PLC program to control the LCD display screen, and displays the working time in full Chinese;
2. Equipped with vacuum actuators, Schneider actuators;
3. The time of the dust blower is automatically alternated;
4. The vibration and stop vibration time automatically alternate;
5. The dust blower, dust vibration, and total test time can be controlled separately;
6. This controller has the following arbitrary setting control functions
a. Dust blowing time (stop, blow): Choose any time setting for continuous or periodic dust blowing
b. Vibration time: The vibration and stop vibration times automatically alternate, with adjustable vibration times of 99 minutes and 59 seconds
c. Preset test time: The maximum test time is 99 hours and 59 minutes
d. Power on: disconnect disconnect disconnect 7. Non fuse protection switch, over temperature, overload, leakage, fully sheathed terminal block, with automatic shutdown protection, etc.

The dust test chamber of this experiment meets the national electrical safety standards, wiring specifications, and all wiring ports are clearly marked without exposure. The studio is absolutely insulated from all power sources, ensuring safety and reliability. Complete safety protection functions (as follows): reliable grounding protection device. Leakage/circuit breaker protection. Overload fuse protection. over temperature protection
