What is a symmetric power supply?
A stabilized symmetrical power supply unit is an embedded circuit, or stand alone unit, the function of which is to supply two complementary stable voltages to a circuit or device that must be operated within certain power supply limits.
What is symmetrical power relationship?
Symmetric relationships are characterized by a balanced mutual relationship, based on similar allocations of power resources. In this context, symmetric conflicts may be spoken of when the dispute takes place between coequal enemies.
What is an example of a symmetrical relationship?
In healthy symmetrical relationships, the two parties mirror each other. An unhealthy example of symmetry would be of two siblings who are brutally competitive with each other. Neither can rest in their anxiety to always be on top.
What is a parallel relationship?
The relationships may comple- ment or compete with each other. A couple relationship may be a consensual or marital union or a living-apart-together (LAT) relationship. When someone simultaneously has a sexual relationship outside of the steady couple relationship, this is called a parallel relationship.
Can a 12 volt symmetric power supply be used?
Here is the standard symmetric power supply using the Positive and Negative Voltage regulator ICs. It can give +12 volt and – 12 volt DC with a common ground. This power supply is ideal to power amplifier circuits that require well regulated symmetrical power supply. It can give 1 ampere current to the circuit.
What is the regulator for a symmetric power supply?
IC2 is 7912 negative regulator and its pins are slightly different from 7812. See the connection in the symmetric power supply schematic. Regulated outputs from the regulator ICs are available from pin 3 which can be used to power the circuit. Capacitors C3 and C4 act as noise filters to give clean DC.
What does solder do to a power supply?
Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.
