 PTC water heating element

Commonly used underside water heater:

Type	Width	Thickness	Length	Applied voltage	Surface temperature without water	Power in 25  water
31# plate, aluminum	13.7	5.2	65mm	12~36VDC,100~240VAC	260	80W
31# plate, aluminum	13.7	5.2	65mm	12~36VDC,100~240VAC	140	40W

12# plate, aluminum	63	7.0	80mm	12~36VDC,100~240VAC	140	120W
37# plate, aluminum	90	7.0	120mm	12~36VDC,100~240VAC	240	680W
37# plate, aluminum	Φ85	7.0		12~36VDC,100~240VAC	240	500W

Notice:

1) The length of the plate could be selected by customer between some range, larger power could be reached with larger plate. But larger plate might result bad heating conduction because the connectting gap on interface.

2) The surface temperature without water, could be between 80~260, the higher is this temperature, the larger is the power.

3) The stable temperature of water could be affectted by the power of PTC, cubage of water, the shape and material of container, heating dispersion, vaporation of water.
