The new drivers have an input range of 9-18VDC for the LDH-45A-X model and 18-32VDC for the LDH-45B-X. The output current for both models is 350mA/500mA/700mA or 1050mA. Furthermore, the LDH-45 series is designed with both PWM and analog dimming capabilities. Therefore, remote ON/OFF control and output current adjustment can be achieved by connecting an external PWM signal or an analog voltage between 0.25-1.3VDC, accommodating the energy-saving dimming requirements of various lighting fixtures.
The LDH-45 series boasts up to 95% efficiency and operates within a range of -40°C to +70°C in ambient temperature with free airflow ventilation. All models are fully enclosed for enhanced heat dissipation, dust protection, and moisture resistance. They also offer two input/output connection options: pin or cable. Incorporating an EMI filter, these LED drivers meet EN55015 EMI requirements for lighting without the need for any additional external EMI filtering components. 
Other standard features include short-circuit, overvoltage, and undervoltage protection. These models are suitable for outdoor LED lighting applications, tunnel lighting, home lighting, and all types of solar-powered garden or street lighting panels.
