How a variac works
WebHow does A Variac Works and how to use. A Variac is an AC power supply with an adjustable output voltage. It uses a step-down transformer to reduce high-voltage AC mains (115/230V) to a lower voltage suitable for electronic devices. The high-voltage secondary winding of the transformer feeds power to your device through an outlet or plug. Web16 de nov. de 2011 · Objective: To remotely control the output voltage from a variac. Once the required voltage has been sent the variac must track that voltage without further intervention from the host PC / PLC. The voltage can be changed by the host. The variac will then track this new voltage. Technical Details: Input Voltage 230VAC 50Hz.

Web3 de abr. de 2024 · This power supply transforms the voltage coming from the variac and steps it down by a ratio of about 120:40 (or 3 to 1). So theoretically, it is 3 times easier to dial in a specific voltage (i.e. more accurate) than just using the un-transformed variac voltage. Some other features of this variable AC power supply are that it has fuses for both ... Web12 de jul. de 2024 · A variable transformer is a transformer that allows for fine adjustments to the output voltage. A typical variable transformer can be adjusted from 0% to about 117% of the input voltage. A variable transformer usually consists of a wiper or brush that can be rotated across the windings to create a variable turns ratio.
