Dustproof Testing Machine

SC-015 Dust-proof Test Chamber (Sand Dust Chamber) is applied to physical and other related performance tests for electronic and electrical products, lamps, electrical cabinets, electrical components, automobiles, motorcycles and their parts and other products under simulated dust climate conditions. Verify whether the performance of the product meets the requirements through verification after the measurement, so as to facilitate the design, improvement, verification and factory inspection of the product. The dust test chamber is applicable to the IP5X and IP6X dustproof test.

Standards:
IEC60529:1989 +A1:1999 +A2: 2013 “Degrees of protection provided by enclosures (IP Code”
IEC60598-1 Luminaires – Part 1: General requirements and tests
GB2423.37-89 (Test L: dust test methods)
GB4208, GB/T 4942.2-93(protective casing grade of low-voltage apparatus)
GB7000.1 “Luminaires Part 1: General Requirements and Tests”
DIN40050 “Road vehicles — Degrees of protection (IP code)”

Specifications:
• Temperature range: RT+10~50℃
• Standard wire diameter of metal screen: 50um; Standard spacing between wires: 75um
• Test dust: dry talc powder; Talc powder dosage: 2~4kg/m; Dust drop method: free falling
• Total test time: 0~999H (adjustable); vibration time: 0~999H (adjustable); time accuracy: ±1 second
• Vacuum: 0~10Kpa (adjustable); Pumping speed: 0~4800L/H (adjustable)
• Sample (EUT) power connection: Refer to the rated input of the sample, but the current can’t be greater than 10A
• Safety protection function: leakage protection, short-circuit protection
• The shell is made of domestic high-quality steel plate, and the surface is sprayed with paint, which is beautiful and durable.
• The inner chamber, sample rack, etc. are made of stainless steel plates to ensure that they will not rust for a long time.
• There is a transparent observation window (toughened glass) on the door, and an LED lighting lamp is installed in the chamber to facilitate the observation of the internal test situation.
• There is a device for replacing dust at the bottom of the chamber, which can easily 100% replace the used dust.
• A vibration device is installed to ensure that the dust does not stick to the wall and condense. The working time of the device is adjustable, and it can work automatically and alternately.
• There is a suction pipe in the chamber, which can complete the vacuum action on the sample (sample should reserve the suction hole position).
• Dust chamber testing control system: 7-inch touch screen + Panasonic PLC. The dust blower, dust  vibration and total test time can be controlled separately. This controller has the following various arbitrary setting control functions:
1. Dust blowing time (stop, blowing): can arbitrarily choose any of continuous and periodic dust blowing time to setting;
2. Vibration time: vibration and stop vibration time are automatically alternated;
3. Preset test time: the maximum test time is 99 hours and 59 minutes;
• Heating system: The circulating air duct is equipped with a heater to heat the dust to avoid dust condensation. The heat of the muffler mica sheet heating ring is safe and stable.
• Vacuum system: equipped with vacuum pump, vacuum pressure, air filtration, flow meter, pressure regulating triplet, connecting pipe.

PS. Other size or Walk-in Dustproof Chamber can be design according to customer’s request. It can be customized to conduct IP5X and IP6X, IP5KX and IP6KX tests according to the ISO 20653 Figure 1 (LISUN model is SC-010-56K, SC-015-56K and SC-020-56K. Arizona A2 Dust with extra cost).
