A CC LED driver balances the output current from each channel to ensure reduced EMI interference and maintain the long lifetime of LEDs. The CC LED driver circuit allows the driver to operate in the ‘constant current region’ also ensuring there is no variation in the brightness of the LEDs. This means you do not have to use resistors or control the current being fed to the LEDs so they can be used in series as long as the forward voltage is within the specified output range of the LED power driver. Constant Voltage (CV) LED Drivers ① Add suffix for dimming option, “D” (0~10V), “P” (PWM) * Unless otherwise specified, all the above parameters are measured at ambient temperature of 25°C and Vin=100 ~ 277VAC CV LED drivers are designed to maintain a Constant Voltage during operation regardless of the current variations between 0-100%. A CV LED driver is ideal for paralleled LED lighting arrays because they generically have an in built resistor to control the current, therefore a CV driver would be required to convert the AC power to the required DC voltage. LGE SERIES MECHANICAL SPECIFICATION Dimensions in mm Weight: 1200g What is the Difference between Constant Voltage (CV) and Constant Current (CC) Drivers? With Constant Voltage the LED module only requires a fixed voltage often 12VDC or 24VDC. The current is usually regulated by either resistors that have been wired in series 78 www.pairuigroup.com | [email protected] | Tel: 86 (514) 8279 1592 with the LEDs or by an on board/built in regulator that the LED module may have. CV loads may be added in parallel across the output of the driver until the maximum output current is reached. This arrangement is often used in installations where the number of LED modules being connected is unknown however may provide inconsistent Led performance and reduced life. With Constant Current the reverse is true. The current is fixed by the driver whilst the voltage will vary depending on the load. The more LEDs that are attached the higher the output voltage will be up to a maximum set by the driver. This can provide uniform brightness and color behavior of the LEDs with no negative impact on LED Lifetime. How will I Know whether to Use a Constant Voltage or Constant Current Driver with my LEDs? Usually the manufacturer of the LED module will specify whether it is for use with either a Constant Voltage or Constant Current driver. You cannot run an LED module designed for CC from a CV supply without damaging it. However a CV LED load will run (albeit inefficiently) from a CC driver. Another indication is if the LED module is rated in milliamps (mA) or volts (V). Milliamps indicates a CC driver and Volts means a CV driver is required. 79
