Fixed Voltage Regulator

Fixed voltage regulator converts an AC voltage coming from the power transformer into a constant and stable DC voltage, having a very low ripple component. They are widely used for supplying a stable voltage to low-power equipments such as sensors, analog modules, initiators, etc. housed in an electrical cabinet.

Function and design
The fixed-voltage regulator is provided with an internal diode, which protects it against induction peaks. There is an integrated thermal overload protector, which provides extra protection. The protector disconnects the fixed-voltage regulator in case of an excessive load. A miniature fuse is also supplied to protect the component. All inputs and outputs have double screw connections; and are supplied with a test point. A green LED indicates the appropriate functioning module in the output.

Uses & Applications
Fixed voltage regulators are used in diverse applications including:

• Sensors
• On-card regulation
• Analog modules
• Telephone applications
• Microprocessors
• Personal computers
