LDH-25/65Series 25/65W DC/DC LED Power Supply
By: Rex Lin/Product Manager
Global warming has drawn enormous attention to the green energy and DC House application; many countries start to promote energy-saving and safer electricity usage. MEAN WELL develops direct current (DC) input LED drive power supply : LDH-25/65 series for green energy LED lighting applications, including LED solar street lights or equipment with secondary battery applications, such as camping car/Yacht applications. LDH-25/65 series provide customers options for reducing conversion losses between DC bus to AC/DC driver.
LDH-25/65W which are designed as step up mode DC/DC LED driver can be used with a secondary battery bus. It is suitable to operate with DC 12v or 24V Battery then boost output voltage for LED board, including 0-10V/PWM dimming function. It can be applied with a regular wall dimmer or wireless dimming controller. Each series can offer different output current, such as LDH-25 with 250/350/500/700 m A and LDH-65 with 700/1050/1400/1750 m A output current. Those output current spec is for most of solar lighting or interior lighting applications.
