HGV INDUCTION HEATER
• P - Transmitted power
Indicates the current output power of the unit in watts, which corresponds approximately
(after deducting the loss of the cable and heating head) to the power or energy introduced
into the material to be heated. It is therefore a parameter directly related to the heating rate
and temperature. This transmitted power increases with increasing distance (decreasing
distance) between the coil and the material.
• Po - Output power
Depending on the inverter output power and indicated in VA (volt-amperes). This is called
"apparent power". It is directly related to the strength or intensity of the magnetic field
produced by the coil. When the distance between the induction coil and the material
decreases, or when less magnetic or non-ferrous metallic materials are heated, this output
power must increase in order to maintain the same amount of energy or heat introduced
into the material, thereby increasing the loss. The increase in output power results in a
higher transmitted power, which can be used to heat non-ferrous metals, for example.
• PF - Power factor
This indicates the relative quality of the heating induction circuit and is directly related to
the connection between the induction coil and the material, which makes this parameter
very useful for selecting the optimal coil. The closer the figure is to 100%, the higher the
efficiency of the transmission of heating energy to the material, and vice versa. In general,
if PF=100%, all the energy goes directly into the material and the heating has maximum
efficiency. With a lower FP, only part of the energy is transmitted into the material.
The PF will be higher with a more specific adapter, applied firmly to a thick material. Distance
quickly reduces FP. For open coils, the more precisely the coil rests on the material and the
smaller the distance between the coil and the material, the higher the PF is and the more
efficient the heating. The recommended distance is about 2-5 mm. In the case of smaller
spaces, the heat from the heated material is transferred into the coil, resulting in a faster
overheating of the unit.
• Frequency "FrE"
The current heating frequency, which must be between 25 and 40 kHz with a correctly
selected coil, depending on the load and the material to be heated. In the event of a
significant deviation, the device displays a warning, which means that the user must use a
more appropriate coil. If the frequency exceeds the limit values, the device switches itself
off and signals an error.
• Output current
Indicates the current supplied by the inverter to the resonance circuit in Amperes.
• Input current
Indicates the current consumption in Amperes.
