The difference between the rated voltage of the cartridge heater and the working voltage
Speaking of rated voltage and working voltage, many people don't understand these two concepts very well. Let us understand the difference between the two:
1.Rated voltage
The rated voltage of the cartridge heater refers to the voltage specified on the design and marked on the outer casing of the cartridge heater and connected to the cartridge heater. Or in other words, the rated voltage is the voltage given by the customer when we ask us to process it. Generally there are 24V, 48V, 110V, 220V, 380V and so on.
2. Working voltage
For a single cartridge heater connected to a power source, the operating voltage of the cartridge heater refers to the voltage connected to the component specified in the design, that is, the rated voltage.
For a group of cartridge heater connected in series to the power supply, the working voltage of the cartridge heater refers to the voltage connected to this group of heating tubes as specified in the design.
If the customer does not clearly distinguish between the rated voltage and the working voltage, then when used, there will be two cases if it is not handled properly, one is that the cartridge heater does not generate heat, and the other is that the cartridge heater has a high temperature. So everyone must understand the difference between the two voltages before applying the cartridge heater.
