Frequently asked questions

What is variable direct current?

What is a variable DC power supply? A variable DC power supply is a DC power supply line that allows the users to easily adjust the output voltage and current via potentiometers or a computer interface. It is also known as an adjustable DC power supply line. How to select a variable DC power supply 30V 6A system?

What is variable voltage current?

Variable voltage/current variable frequency source is used to simulate the main conditions of different countries. Also, it is used for verifying the frequency response of power devices, and frequency relay components. Variable current variable frequency sources are used for checking current transformers. 50 to 60 Hz.

What is variable voltage control?

A variable voltage regulator is a type of electronic circuit that is designed to automatically maintain a constant voltage level control. However, unlike a fixed voltage regulator, a variable voltage regulator allows the user to adjust the output voltage to a desired level within a certain range of control circuits.

What is a variable voltage transformer?

Variable transformers are transformers that can put out differing amounts of voltage from the same input voltage supply. There are trademarked versions of these transformers and there are versions that are simply sold as variable transformers power supply, some of which are built to custom specifications.

Can we convert DC to DC?

Most DC-to-DC converters are designed to move power in only one direction, from the dedicated input to the output side. However, all switching regulator topologies can be made bidirectional and able to move the power supply in either direction by replacing all diodes with independently controlled active rectification.
