Life service
Summary
The motor locked-rotor of compressors such as refrigerators and washing machines is 5~10 times of the steady-state current. The electric heating part of the air conditioner and the surge of the light belt bring the current to 10~15 times of the rated current instantaneously. Precise control of indoor temperature rise, energy saving, requirements for NTC negative thermal temperature coefficient and other solutions. In terms of complementarity with semiconductors, it can provide better suggestions by accelerating contact closing and suppressing surges.
