Description

Mean Well LDH-45 DC-DC Constant Current LED Drivers feature a step-up mode that boosts your input voltage so you can power more LEDs at once. This low voltage driver is available with output currents of 350, 500, 700 and 1050mA. The LDH-45 series boasts 95%efficiency! Offering PWM +analog dimming and remote ON/OFF control (EN55015 compliable), these drivers are great for street lighting, landscape and architectural lighting, and household lighting applications.

A & B Series

You will notice the LDH-45 comes in an A and B series. The only difference is their input and output voltage. The A series needs an input from 9~18VDC whereas the B series needs an input from 18~32VDC. The B series will also be able to output higher voltages. See tables below for specific input and output specifications.

Connection Style Variations

LDH-45 constant current LED drivers come with wire or pin style connections.
