5V 12V 24V 220V PTC Heater Element Constant Temperature Thermostat Heating Plate

Product Parameter:

Material: Aluminum
Voltage: 5V 12V 24V 220V
Power: 2 ~ 40W

Size: 20*50*5mm

Lead length: ≥70mm

PTFE high temperature resistant wire, the lead length is greater than 70mm, the surface is constant temperature, the error is ±10 degrees.

It can only be boiled dry, can not be opened, can not be tapped, can not be soaked in water. For example, 12V/60°C means that the surface of the heating element with a voltage of 12 volts is dry-fired at a constant temperature of about 60°C. When the temperature rises, it is 8 watts. After the heating plate is kept at a constant temperature, the resistance becomes larger, the current becomes smaller, and the power is reduced to about 2 watts.

Working principle:

The internal heating body of the PTC heater is a positive temperature coefficient thermistor, whose resistance value shows a step increase as the temperature of the PTC thermistor body rises, the higher the temperature, the greater the resistance value.

About the power:

PTC heater power has small to large and then to small, and finally stable. Stable power is directly related to heat dissipation, heat dissipation is fast, power consumption is also more, we mark the maximum power dissipation, the actual use of power to be less than the maximum power dissipation.
Strictly forbidden to use in corrosive and flammable and explosive occasions, strictly forbidden to put into water, strictly forbidden to knock, strictly forbidden to open the hole.
The same voltage of more than one heater wiring can be used in parallel, more than one heater can be installed side by side, the heater can not overlap between the installation, otherwise the heat will be offset.
Multiple heaters should be used in parallel, the more heaters, the more power.
Lower power supply voltage will make the heating time longer and the power smaller, but the temperature is basically constant (slight temperature drop).

Uses:

Battery, security, medical, scientific research, industrial motor, aerospace, and other electronic and electrical small power heating preheating moisture insulation. Quite a wide range of applications, such as electric mosquito heaters, shoe warmers heaters, incense burners heaters, heaters, electric cup heaters, coffee machine heaters, yogurt machine heaters, automotive parts insulation, diesel alcohol heating, instrumentation heating moisture removal and many more can be developed There are many more uses that can be developed.

(Note: The temperature marked here is the highest temperature limit value of the surface temperature of the heating piece itself in the empty burning state, this temperature does not represent the use of the temperature; the use of temperature controlled by the environment and the site of heat absorption; empty burning surface temperature limit and the use of temperature is completely different from the two temperatures; and everyone to explain this misunderstanding.)

Note:

The power of PTC products is related to the heat dissipation conditions! The better the heat dissipation, the higher the power.

The maximum power is the simultaneous dissipation of heat on both sides of the heating plate under extremely good conditions. If the heating plate only touches the object on one side, the maximum power is directly reduced to half.

The dry burn power is the power of the heating plate when it is suspended in the air without contacting anything and dissipates heat naturally.

The rated temperature we have marked is the dry firing gauge temperature of the heating plate, which is the gauge temperature of our heating plate when it is suspended in the air without touching any objects. Connecting out different media, good or bad contact, the size of the object being heated, thickness, material, ambient temperature, air circulation, etc. all determine the temperature to which the object being heated can be stabilised. So this is not just our heating products can decide, it is generally recommended that the user test to know the.

Electric heating products have an inrush power (inrush current), which is generally 1~2 times the maximum power.

Low voltage products should not only meet their voltage, but also need to pay attention to the current, if the power supply current cannot meet to the product's inrush current, it will happen that the product will be slow to heat up, low temperature, or even short circuit possible!

Payment

We accept multiple payment methods supported by the platform.

Shipping

We ship to worldwide. We only ship to confirmed eBay addresses. Your eBay address must match your shipping address.

Orders processed within 24-48 hours of payment verification. It will take 15-25 days for delivery. But customs will random inspection some parcel, so that's why some parcel need more than four weeks to arrive. Shipping time is only estimated and not guaranteed.

For all international orders, shipment is via eBay's global shipping programme therefore eBay will determine the costs of shipping to your destination and goods are shipped using a fully tracked service.
