LED Drivers

LED drivers are essential components of most LED lighting applications in commercial, industrial and consumer products. A LED driver is an electrical device that regulates the power to an LED or a string of LED’s by providing the correct amount of electrical power and managing the heat dissipation of the LEDs. LED drivers also provide a variety of features such as dimming control and protection from electrical surges.The LPH-18-12 LED driver is an advanced driver for LED lighting applications. It is a highly efficient, power factor corrected, offline LED driver that was designed to meet the needs of modern LED lighting fixtures. This driver supports continuous conduction mode (CCM) as well as discontinuous conduction mode (DCM) operations, eliminating the need for external dimmers and providing excellent dimmer compatibility. The LPH-18-12 operates from a wide range 90-264Vac input voltage range and is capable of delivering up to 150W of output power with a highly stable constant output current. It also includes a wide range of dimming modes, including 0-10Vdc, 10V PWM and DALI, and is equipped with multiple protections (open-circuit, short-circuit, over-temperature, over-voltage protection). Furthermore, the LPH-18-12 LED driver is built to meet UL1310 Class 2 safety standards and EN-60950-1 (IEC60950-1) safety requirements, enabling the LED lighting fixtures to perform in safety-critical applications. The LPH-18-12 LED driver utilizes an active power factor corrected flyback topology for superior efficiency, enabling it to meet the stringent 80+ PL (power supply efficiency) requirements without compromising on performance or cost. The integrated primary side average current limiting circuit provides over-power protection. The driver also includes an adjustable output current limit to prevent excessive load damage.The integrated constant current output of the LPH-18-12 allows for direct driving of LEDs with low ripple current. This provides optimal efficiency for LED light sources as well as enhanced visual performance. The output voltage is adjustable allowing the user to customize the LED lighting output for various applications without needing to replace the LEDs. The flicker-free operation of the driver ensures flicker-free operation at low light levels and a smooth dimming transition.In summary, the LPH-18-12 LED driver is an advanced high performance power source designed for driving LEDs in general illumination, indoor and outdoor lighting, retail and commercial lighting, entertainment lighting, signage lighting, and other lighting applications. Its feature set includes high efficiency, wide dimming range, multiple dimming modes, along with protection and safety features. The LPH-18-12 offers superior power factor correction and flicker-free dimming, assuring safe and reliable operation.
