LED Power Supplies - Constant Current
Just as the name suggest, here are a selection of constant current power supplies to operate your LEDs... LEDs require a device that can convert mains AC power to DC voltage, and regulate the current in the circuit. The driver converts 230V AC power to low-voltage DC power required by the LEDs, the driver also protects the LEDs from line-voltage fluctuations. LED chips, LED strips, LED strings, LED modules, LED bars and LED arrays can all be constructed in different ways. Some have a serial connection with a current-limiting resistor above them. Some use the on-board constant current regulator to replace the current-limiting resistor. While some add current balancing and smart protections onto the printed circuit board. The net results can be confusing to the customer. Our advice is to stick to the driver suggested by the manufacturer of the LED product. If however you have a specific requirement please contact us for advice because some drivers are interchangeable i.e. a constant current driver with a 12v supply may be used to power some LED product that suggests a constant voltage driver should be used.
