What is a variable AC power supply?
A variable AC power source is a controlled, yet variable, voltage solution. Variable AC power sources are commonly used in conjunction with test equipment to simulate extreme variations of voltage condition. Event conditions such as sags, sustained low voltages, surges, over-voltages, sustained over-voltage conditions, and high/ low nominals beyond commercially available power sources could cause a device to malfunction.
What are the types of variable AC power supplies?
A variable AC power source comes in three types, including simple manual, motorized, and sophisticated interface with automatic control schemes. The environmental and monitoring parameters along with the voltage and load amperage requirements of the application will help determine the best type of variable AC power source.
How do you make an adjustable voltage power supply?
Variable AC power sources are engineered assemblies made up of standard or special variable transformers, zig-zag neutral generating transformers, and multi-tapped buck-boost or special ratio auto-transformers. Additionally, electrical components such as SUPERCON® specialty connectors, circuit breakers, contactors, bypass switches, emergency power-off devices and meters are commonly included in variable AC power source assemblies. Experts position and wire each all required components together to make an effective and cohesive assembly.
