Fast ultra-low humidity electronic moisture-proof box YS-490 industrial PCB SMT SMD automatic dehumidification drying cabinet


1 strong movement: strong humidity control, dehumidification fast, minimum humidity control ≤ 5% RH or less.

2. Power-off and moisture-proof: With automatic power-off and moisture absorption function after power failure, there is a certain moisture-proof function in power failure, and the humidity rises <10% RH within 24 hours after power failure.

3. Normal temperature dehumidification: no thermal quality change problem, no temperature difference water problem. Unaffected by the environment, the temperature difference between the environment is as high as moisture.

4. Good air tightness: power saving, no heat, no dust, no dripping, silent operation.

5. Long service life: no need to replace dry materials for repeated use, micro-mechanical airtight valve switch intake and exhaust control, intelligent automatic low-pressure fixed-point control.

6. No safety hazard: the movement adopts two-stage power supply, one group absorbs moisture and the other group drains moisture to avoid large voltage and lead to tripping.

working principle:

Memory alloy molecular sieve physical adsorption dehumidification:

The dehumidification controller is provided with a top and bottom rotary flap door, and a pair of upper and lower inner and outer (for the cabinet) each have a pair of moisture absorbing moisture, and a special moisture absorbing material (molecular sieve) is attached therein. When the moisture is absorbed, the loose-leaf door is opened inward, and the moisture-absorbing material absorbs the moisture in the cabinet from the moisture-absorbing window, so that the humidity in the cabinet is lowered, and when the moisture is discharged, the moisture-absorbing material is heated and regenerated, and the shutter is turned to open the moisture window outside the cabinet to remove the moisture.

The moisture absorption and tidal cycle work is realized by the program time controller until the set value is reached in the cabinet. The controller automatically cuts off the power because it does not need to be energized during the moisture absorption. The moisture absorption time is long (about 2.5 hours). Short power-on time (about 30 minutes)
