45-Watt DC to DC Step-Up Constant Current LED Driver
LDH-45
The MEAN WELL LDH-45 series DC to DC LED drivers take an input from a DC voltage source, such as a battery or a solar panel, and converts it to a constant current DC output suitable for powering LEDs.
The standard models feature both analogue and PWM dimming and have a wide input voltage range. They also boast a wide forward voltage range, which makes them compatible with a wide range of LEDs. There is also a DALI version available.
There are 2 input voltage range options:
A: 9~18VDC (ideal for use with 12V batteries or solar panels)
B: 18~32VDC (ideal for use with 24v batteries or solar panels)
These LED drivers are fully encapsulated and have a high efficiency rating. They are available as a PCB mount module or with wire terminations.
See table below for models in the range.

Disclaimer
Due to demonstrated incompatibilities between some DALI systems, it is strongly recommended that all DALI products are tested with intended equipment before installation. DALI drivers which are incompatible with untested applications will not be accepted back as warranty claims if they are not tested as being faulty.
