A dual DC power supply is simply the supply of direct current to a machine from two outlets. It is a smart way to boost up one’s power supply at the cheapest price. And the best part is that it is easy to install. Before we dive into the advantages of a dual power supply, let’s consider what a dual voltage and dual trace oscilloscope means.
There are some electric motors that can operate on two or three different voltages/lines, depending on how the motor is built and connected, in which case the voltages are either multiples of two or three of another. Another term worthy of mentioning is the dual trace oscilloscope, which is simply the oscilloscope that can function and simultaneously display two signals.
1. Constant Power
In a single–phase circuit, instantaneous power varies sinusoidally. However, a dual power supply ensures constant power to a device when one power source fails for any reason.
2. Multiplies Supply Frequency
Dual DC power supply double the the supply frequency.
3. Increases Power Output
More power is guaranteed whenever a dual DC power supply is engaged, compared to a single power source. Just like supply frequency, it multiplies the power supply by two.
A dual DC power supply is less expensive. Dual DC power supply is cheaper than running on a single power supply. It also comes in useful in situations where one needs more power to boost already available amps. The additional power supply doesn't have to be of a higher wattage as it may not need to run a heavy load. For instance, the old power can be used to run the fan and pumps and the new DC source can power the motherboard and other components of the desktop computer.
5. Ease of Installation
Addition of a dual DC power supply to an already existing direct current power supply source is easy and can be completed in less than 20 minutes. Simply identify the source for the second power supply and run a cord out of the case to connect the green pin and any black pin coming from the main power supply to the auxiliary. It is as simple as that.
6. Constant Power
A rig that uses dual DC power supply is guaranteed with constant and uninterruptible power supply. Again, a desktop computer can receive dual power supply, one for the fan and the second one for the motherboard. This setup ensures that power is not compromised whenever a device is switched on due to fluctuation of voltage. An electricity power supply can fluctuate whenever we add a load to it. Fluctuation of electric current is one of the major causes of damage to computer systems so a stable power is a benefit.
7. Convenient Temperature
Extra power supply does not change the case temperature as may logically be expected.
As an example, dual power makes it easy to switch off the air conditioning device of an ATM machine when not needed without interrupting the entire power supply.
A dual electric power supply is important for several reasons. Not only does it ensure stable power supply to a device, but it also helps prevent system damage. It allows for multiple usage of power by increasing power output. In short, it ensures regular direct current power supply.
