Electric automatic check door circuit diagram

Published:2011/5/9 21:26:00 Author:Nicole | Keyword: electric, check door

It is a electric automatic check door circuit diagram, it is fixed a PTC thermal resistor component on the electric check door, this control system is composed of bimetallic strip, electrical heating coil, choke valve relay. When it is lower than the set point of temperature, the choke valve is closed by bimetallic strip, then the starter begins to work, the choke valve relya contact is closed by the voltage of voltage adjuster L terminal, the current flows electrical heating coil, the temperature of bimetallic strip rises, after the temperature rising, the choke valve opens slowly. When the bimetallic strip is heated enough, choke valve opens fully, it uses thermal resistor to control the current of electrical heating coil. (View)

Ordinary filter circuit diagram

Published:2011/5/10 2:43:00 Author:Nicole | Keyword: filter

Ordinary filter circuit diagram
In the ripple and noise susceptible circuit, it can add a filter to DC/DC input terminal and output terminal, it can reduce the ripple and noise. It can absorb the peak voltage of input terminal by importing additional capacitance, it also can store energy and keep voltage stable, The output ripple can be reduced by exporting additional capacitance, the capacitance value too large or ESR too low will easily cause start up problems; if it requires very low ripple, it can adopt LC filtering network or use power module with low ripple output.
