What's a dual run AC capacitor ?

• A capacitor is an electric component that temporarily stores an electrical charge and AC capacitor is a key component to start air conditioner motors.
• A dual run capacitor supports "TWO" electric motors, one section for the condenser fan motor and the other for the compressor motor. Beacause of technological innovation, the dual run capacitor can saves space by combining two capacitors into one case.
• Round cylinder-shaped dual run capacitors are commonly used for air conditioning, it can help in the starting of the compressor and the condenser fan motor.
• Air conditioner capacitor is small in size, lightweight, heat resisting and anti-explosion.

Dual capacitors come in a variety of sizes, depending on the capacitance (µF or MFD) and the voltage.

 

1. The capacitance (µF or MFD) must be the same or stay within ±6% of its original value. Example: 45 µF cap can be substituted by 42.3 to 47.7 µF with the same or better voltage ratings capacitor .
2. A 440 volt capacitor can be used in place of a 370 volt capacitor, as it can work better, but the 370 volt capacitor can't be used in place of a 440 volt capacitor.It will work for a while or will fail prematurely, because exceeding the capacitor's rated voltage will cause the dielectric to break down and the capacitor to short out.

"TIME" to Replace

The Dual Run AC Capacitor needs to be replaced when the following conditions occur:

1. The fan wouldn't spin - the condenser fan motor maybe died.
2. The air conditioner is making humming sound, but no air flow.
3. Air conditioner stopped cooling - the compressor in the condenser maybe not coming on.

"SUPER EASY" to Install

• First, Shut off power to the A/C at both the thermostat and the breaker box. Secondly, taking out the capacitor.
• What's important, make sure you know which wire is for which terminal - three terminals on the top are labeled "Herm"/"H" for the compressor motor, "Fan"/"F" for the fan and "C" for the common line.
• Direct replacement, no need to change wiring or adapter.
• Last but not least, self-install will save you a substantial amount of money!

What is a starting capacitor and a running capacitor for a motor?

As we all know, a single-phase AC motor is not like a three-phase motor. It can turn when it is powered. It needs a starting torque to rotate, and the clockwise and anti-clockwise of this torque determines the steering of the motor, and there are many ways to start. Among them, the capacitor start is one, which is customarily called the start capacitor, and the single-phase motor needs it to rotate smoothly.

However, some single-phase motors have more than one capacitor, and some motors have two capacitors. Why? Because some motors are equipped with a starting capacitor and a running capacitor, what is going on?

The difference between start capacitors and run capacitors.

Running capacitor: It is connected to the secondary winding to form an alternating magnetic field after phase-shifting the alternating current, and forms an approximately circular elliptical rotating magnetic field with the alternating magnetic field of the main winding. So he can be the same capacitor, but its role is different.

No matter what kind of capacitor, it has a starting effect at the beginning of the motor. However, when the motor reaches about 75% of the rated speed, the starting capacitor is automatically disconnected by the centrifugal switch, and the running capacitor continues to work with the motor. The process of starting the motor is actually the process of "column phase". Because a single-phase motor is different from a three-phase motor, there is no phase difference, and a rotating magnetic field cannot be generated. The function of the capacitor is to make the starting winding current of the motor lead the running winding by 90 electrical angles in time and space to form a phase difference. Among them, the running capacitor also plays the role of balancing the current between the main and auxiliary windings. Since the starting capacitor works for an instant and a short time, the withstand voltage is required to be above 250V, while the running capacitor needs to work for a long time, and the withstand voltage is required to be above 450V.

The starting capacitor is to make the starting coil of the single-phase motor energized at the time of starting, and then cut off after starting. The running capacitor is to make the motor perform capacitance compensation during the operation, so the starting capacitor cannot be less, and the running capacitor can not be used.

The running capacitor is the starting capacitor used when the press is working normally. When the press starts, it starts the press together with the running capacitor. After the press is turned up, the start capacitor is disconnected. The running and starting capacitors are together, but one of the starting capacitors is open, and the starting capacitor is useless when the motor turns. What is the difference between the starting capacitor and the running capacitor? That is the capacity of the starting capacitor is large, generally 2-5 times that of the running capacitor, while the capacity of the running capacitor is small, and the capacity difference between the two is huge and easy to distinguish.
