Installation and operating instructions

When designing, it is necessary to calculate the resulting power based on the supply voltage, cable length and resistance per meter.
Choose the cable so that the operating temperature matches the device design and ambient conditions.
For proper and safe operation, we recommend ensuring even heat dissipation from the cable surface.
Do not shorten or modify the cable without verifying the resulting electrical power and current load.
During installation, take care to avoid mechanical damage to the insulation.

Safety notice

The product is intended for use in accordance with the appropriate electrical and thermal parameters of the application.
During operation, the cable surface may heat up to an elevated temperature.
An incorrectly selected length or supply voltage can lead to excessive thermal load.
We recommend that the installation be carried out only with appropriate protection and checking of the power supply parameters.
The product is not intended for use without appropriate structural protection in applications where direct contact with sensitive or flammable materials could occur.

How does the calculator work?

Input Values
The user enters three main values:
- Source Voltage (V): The voltage supplied to the heating cable.
- Cable Length (m): The total length of the heating cable.
- Cable Resistance (Ω/m): Resistance per unit length (usually in ohms per meter).
Calculation of Total Resistance
The calculator first computes the total resistance of the cable using the formula:
$R_{total} = resistance per meter \times cable length$
This means that the longer the cable, the higher the total resistance.
Calculation of Current using Ohm's Law
According to Ohm's law, it holds that:
$I = \frac{U}{R}$
Where $U$ is the voltage and $R$ is the total resistance. Therefore, as the cable length (and thus the resistance) increases, the current flowing through the cable decreases.
Calculation of Total Cable Power
The total power delivered to the cable is calculated using the formula:
$P = U \times I$
Since the current decreases as the resistance (and thus cable length) increases, the total power $P$ also decreases.
Calculation of Power per 1 m of Cable
The power per unit length (W/m) is obtained by dividing the total power by the cable length:
$P_{1m} = \frac{P}{cable length}$
This value is important because the actual heating of the cable depends on how much energy is released per meter. With a very long cable, even if the voltage is the same, the total power is divided over more meters, resulting in a lower power per meter.
Display of Results
The calculator then displays:
- Cable Current (A): Calculated using Ohm's law.
- Cable Power (W): The total power delivered to the cable.
- Power per 1 m (W/m): The power distributed per meter of cable.
- Approximate Cable Temperature: Instead of a numerical value, text is displayed – if the temperature is 20 °C or lower, "Ambient Temperature" is shown, and if the temperature is 90 °C or higher, "Too high!" is displayed. The calculated value is based on an ambient temperature of 20 °C.

Why does the cable's power decrease with length?

Increase in Total Resistance:
The cable's resistance is specified in ohms per meter. When you extend the cable, the total resistance increases linearly with its length. For example, if the resistance is 0.1 Ω/m and the cable is 10 meters long, the total resistance will be 1 Ω; if the cable is 100 meters, the resistance will be 10 Ω.
Decrease in Current:
Since the current is given by the formula $I$ = $U / R$ , a higher resistance results in a lower current through the cable. Less current means that less energy is delivered to the cable.
Total Power and Power per 1 m:
The total power of the cable is given by the formula $P = U \times I$ . As the current decreases, the total power also decreases. Furthermore, this power is distributed along the entire length of the cable. Therefore, the longer the cable, the lower the power per meter, which directly affects the heating. With a very long cable, even if the total power is significant, the power per meter may become extremely low, resulting in inefficient heating of the cable.
