What controls the heating rate of the heater?
How to control the heating speed of the heater depends on the structure of the heater. The frequency converter can only change the frequency of alternating current, so as to change the rotation speed of the motor and achieve the purpose of changing the output power of the motor. and Constant temperature and humidity test chamber In the heater is not rotating, frequency conversion can not control the heating speed.
There are two simple methods:
1. Diode half wave rectification is used to change the effective value of alternating current to change the heating power and heating speed;
2. The advantage of small transformer is that it can be adjusted in many levels, but the circuit structure is complex.
