Notes on Part Numbering

1. PTC FIN PITCH (SH-XXXXM):

• The Power(W) in the Specifications table is based on PTC air heaters with fin pitch 1.68mm(M).

2. PTC INSULATION (SH-XXXXM-XXXS):

• The Power(W) in the Specifications tables are based on PTC air heaters with Single Insulation(S).
• The price of PTC air heaters with double insulation(D) is 20~30% more than single insulation(S) PTC air heaters.
• The power(W) of PTC air heater with double insulation(D) is approximately 10% less than PTC air heater with single insulation(S).
• The PTC air heater with Double Insulation(D) does not have electrode potential on the fins. It is suitable for use where the device may be in contact with other conductive materials (eg. metal); expose to high humidity; with shock resistance requirement; or in products that require superior stability and quality (eg. automobiles).

3. ACCESSORIES (SH-XXXXM-XXXSX):

• The “Other Accessories” in 4, 5, 8, B and D of Part Numbering will not include Thermostat for PTC air heaters with Maximum Inrush greater than 14A.
• However, if specifically require thermostat to be included, please advise our Sales Representatives for possible alternatives.

Specifications (200V~240V)

• Items that are highlighted in the table are standard models. The delivery time for these models are shorter and more economical.
• Customized wattage, length and specifications can also be designed for large quantity.
• The Power(W) specified in the table above is based on PTC heaters with fin pitch 1.68mm(M) and single insulation(S). Double insulated(D) PTC heaters will have 10% less power than specified in the table above (as power in table is based on single insulation).
  (Model: SH-2XXXM-XXXS)

Specifications (100V~120V)

• Items that are highlighted in the table are standard models. The delivery time for these models are shorter and more economical.
• Customized wattage, length and specifications can also be designed for large quantity.
• The Power(W) specified in the table above is based on PTC heaters with fin pitch 1.68mm(M) and single insulation(S). Double insulated(D) PTC heaters will have 10% less power than specified in the table above (as power in table is based on single insulation).
