7-3 Relay
Unlike to other mechanical apparatus, this solid
relay has neither coils nor flexiable terminals.
The relay is made of a solid wafer situated
between the terminal linked poles. This wafer
will produce low resistance (5~23 ) under
room temperature.
TERMINALS
When the compressor is initialized, the current
will run through the Run winding group and the
parralled relay as well as the Start winding group.
In the beginning, the increasing relay resistance
will lessen the current dramtically. The silm
current will keep the relay resistance high and
the relay open . ` `
This relay is called PTC (Positive Temperature
Coefficiency) relay as the resistance will go up
with the increasing temperature.
This solid relay can also be tested by an
ohmmeter. The relay resistance tested under
room temperature must be within the range of
10% of the norminal value indicated on the
specified circuit diagram.
