Does electromagnetic heating control circuit board often burn out?

Reflect on the market at present, many enterprises, they after modification by electromagnetic heating controller, control circuit board will often burn out, all the headaches that come with this, also make to retrofit the businesses, even for the energy-saving new technology question. 

The cause of the above situation, mainly caused by the concept of electromagnetic heating energy saving technology a lot of interest in the industry, is also very popular with the enterprise, want to be engaged in or interested in the industry manufacturers and service point, many people rush to battle too late or no ability to do the necessary to the electronic control technology, using induction cooker control board application directly to the industrial requirements of plastic machine installation, even some of the original do induction cooker manufacturers directly using the original induction cooker movement to use intact. 

Electromagnetism circuit board itself is not the problem, of course, if you use it to manufacture induction cooker will be very stable  won't burn out, and you can have a life. But not use on plastic machinery  for plastics machinery and there is a fundamental difference in the use of the electromagnetism environment, the use of plastic machine environment is induction cooker as household electrical appliances more complicated, the industrial environment exist in the power grid voltage instability, all sorts of all sorts of machine between the harmonic interference, etc., can cause circuit board is not very durable, often burn out. Actually household induction cooker real work time only 2 to 3 hours a day, and the plastic machine working hours on average 12 hours a day, some manufacturers of the machine use longer, therefore, fundamentally different from industrial electromagnetic heating and the induction cooker, whether in the circuit board in the design of circuit protection scheme and the selection of electronic components on demand is different, from the level points of civil and industrial electronic components in a number of different, industrial-grade electromagnetic heater must use the level of industrial-grade above, otherwise often burn out controller is inevitable.
