Product OverviewThe CZCL (Chuanglian) A200AF-4.5 is a 180W LED display power supply that delivers a stable 4.5V DC at up to 40A from 200-240V AC mains. It is the everyday supply for standard LED cabinets, standees and small screens.
Why 4.5VLED driver ICs hold module current constant, so a module draws the same amps at 4.5V as at 5V. Running at 4.5V cuts power by about 10% - 20W less per supply at full load - and keeps modules, driver ICs and cabinets cooler. Qiangli recommends 4.5V for its LED modules. Check that your modules accept 4.5V before switching.
