MeanWell HLG-320H-48A Driver

Description

Constant voltage/ constant current “A” version of 48V driver is voltage and current adjustable up to 53.4V for maximum utility with larger arrays of Luminus CXM22, CLU048-1818, CLU058-1825, and Vero29-B series.

HLG-320H-48 Test Report

Constant voltage/ constant current  “A” version drivers offer the following advantages:

• lower maximum voltage for safer operation
• maximum flexibility for expansion – any number of COBs can be added later on. Every COB added increases efficiency of entire array

Note that dimming for “A” versions are via the potentiometer fixed to the unit- they do not offer remote dimming. Drivers are dimmable to approximately 20% of total load

Also please note all COBs must be same series of similar voltage profile, you cant mix cobs of different models as the lower voltage COBs may not light

Max current: 7.6A can power 48V COBs at the following approximate wattage (actual wattage varies slightly by particular chip):

4@1.9A (~85W ea), 5@1.52A (~76W ea)
6@1.27A (~64W ea) , 7@1.09A (~55W ea)
8@0.95A (~40W ea), 9@0.84A (~42W ea)
10@0.76A (~38W ea)
