[NEW Product] LDD-HS/LS Series (SMD Type DC-DC Constant Current LED Driver) 출시

After the launch of LDD-H/HW and LDD-L/LW series, MEAN WELL further announced two kinds of DC-DC
Buck converter with constant current output for LED driving purpose ~ LDD-HS and LDD-LS series. With
SMD package, they are suitable to be mounted by surface mounted-process (SMT) on the system PCB of
lighting fixture and save the labor cost of installation. LDD-HS features with 9~56VDC input and 2~52VDC
output range while LDD-LS possesses range of 9~32VDC input and 2~28VDC output. Both series provide
multiple output current options of 300mA/350mA/500mA/600mA/700mA/1000mA (1000mA for LDD-HS
only) for LED system designers to choose from. Accompany with the LDD-H/L (pin style) and LDD-HW/LW
(wire style), MEAN WELL currently can offer the DC-DC LED drivers in three different package types from
300 to 1000mA output current and satisfy the demand of various driving current and installation designs.

With non-isolated Buck topology design and high quality components, LDD-HS/LS series possess up to 96%
of extremely high efficiency and can operate between -40~+85°C of ambient temperature by only free air
convection (up to 71°C for 600mA~1000mA models). Built-in EMI filter, these LED drivers comply with EMI
requirements per EN55015 lighting regulation without connecting any external EMI restraint components.
Other standard functions include PWM dimming, remote ON/OFF control, protections for short circuit and
over temperature, wide range of input/output voltage. Besides, the optional conformal coating models can
provide the basic ability of anti-dust and anti-moisture. Suitable applications include street lighting, landscape
lighting, tunnel lighting, household lighting, and all kinds of LED lighting systems.
