Current regulators, alternatively known as CCRs (constant current regulators), are simple but robust devices that offer solutions for LED current regulation. These devices produce constant current even if the load current or input voltage changes. They utilize SBT (self-biased transistor) technology.
Current regulators operate like voltage regulators, the only difference being the way they regulate and how their output is supplied. Voltage regulators have varied currents in order to produce the right voltage level. Current regulators, on the other hand, have varied resistance (voltage) to produce the recommended current output.
If current regulators are not provided the right amount of power or voltage pressure, controlling the current will be difficult. If the power provided is too high, the current in the converter may be too much.
Current regulators use IC-based voltage regulators. They are designed to protect LEDs by utilizing negative temperature coefficients.
Fluctuation is not good for household appliances, especially for devices with motherboards, microchips, integrated circuits (ICs), and processing units. Current regulators used in consumer devices are equipped with constant current regulation circuitry. It is essential for ensuring that damage is avoided by directing current to the device at constant levels.
Aside from consumer appliances, current regulators are also beneficial for machinery and automobiles, as well as for internationally-configured voltage transformers.
Types of Current Regulators
Commonly used current regulators include universal, industrial, and commercial current regulators.
Universal regulators have switches that users make use of when they need the output voltage to change. It is also used to power various devices.
Industrial and commercial current regulators are similar in a way as both are used for specific machinery types, like those that require voltage adjustments for an equipment to work.
Some features of current regulators include the following:
- Negative temperature coefficient
- Wide voltage range
- Voltage surge suppressing-protecting LEDs
- It can be easily turned on
