Buy Voltage Regulators Online at Best Price in India

A voltage regulator is a system or component that keeps a consistent voltage output despite alterations in input voltage or load conditions. It can be constructed with either an electromechanical mechanism or electronic components and can be designed with a straightforward feed-forward or negative feedback system.

These are frequently employed in power supply units to ensure a stable voltage supply. Transistor regulators and commercial voltage regulators are among the various kinds of voltage regulators. These can also be obtained as components for different applications, like DC voltage reducers.

If you are looking for voltage regulator prices in India, you must check out the range of regulators above. At Robocraze, we offer the best voltage controller price in the market. Check out the price of voltage regulators below.

Comparison: Linear vs Switching vs Adjustable Voltage Regulators

Feature	Linear Regulator	Switching Regulator	Adjustable Regulator
How it Works	Uses a transistor to drop excess voltage and maintain a steady output.	Converts voltage through high-frequency switching using inductors and capacitors.	Allows users to set output voltage using external resistors or a potentiometer.
Efficiency	Low efficiency; excess voltage is lost as heat.	High efficiency (80–95%) with minimal power loss.	Efficiency depends on design — linear adjustable types have similar losses to linear regulators.
Output Noise / Ripple	Very low noise, suitable for sensitive analog or audio circuits.	Higher noise and ripple; needs additional filtering for clean output.	Varies by type; may require filtering if used for sensitive circuits.
Complexity & Size	Simple design with fewer components and easy setup.	More complex; requires more components and careful PCB layout.	Slightly more complex than fixed regulators due to external adjustment components.
Heat Generation	High heat output at large voltage differences.	Low heat generation due to efficient conversion.	Depends on topology — adjustable linear types can get hot at high loads.
Cost	Low cost for low-power projects.	Higher initial cost but more efficient for high power.	Moderately priced; provides flexibility for multiple voltage needs.
When to Use	Ideal for low-power, low-noise circuits like sensors and op-amp circuits.	Best for high-power, battery, and variable-input applications.	Perfect for experiments, prototyping, or variable-voltage power supplies.
Limitation	Can only step down voltage (no boost function).	More design effort and possible electromagnetic interference (EMI).	Adjustable linear types still face efficiency loss; switching adjustable may be costlier.

Applications

For high-power or industrial needs, Robocraze offers SCR-based AC voltage regulators and switching modules capable of handling up to 10,000 W.
These are ideal for applications requiring large voltage control and stable performance under load.

Workshops & Industrial Labs: Controlling voltage for heaters, motors, and soldering equipment.

Automation Systems: Regulating AC input for relays, pumps, or lighting systems.

Testing & Prototyping: Adjustable SCR regulators help simulate variable load conditions.

DIY High-Load Projects: Safely control speed, brightness, or power with high-current SCR modules.

Usage Tips for Voltage Regulators

Check Input Voltage: Always ensure the regulator input is higher than the desired output (for linear types).

Add a Heat Sink: Linear regulators (like 7805, 7812) can get hot - use heat sinks for high currents.

Use Filter Capacitors: Place capacitors close to input and output pins to reduce voltage ripple and noise.

Mind Current Limits: Never exceed the rated output current of your regulator.

Switching Noise Precaution: For switching regulators, keep wiring short and twisted to reduce EMI.

For Adjustable Regulators: Use precise resistors or multiturn potentiometers to set accurate voltage levels.

Test Before Load: Measure the output voltage before connecting sensitive components.
