2 PCS Electronic Accessories: 1 x Buck Boost Converter & 1 x DC converterPress the key of coding potentiometer briefly to activate the parameter to be set;The switch of parameter name and bit selection is realized by short pressing the key of coded potentiometer;After selecting the parameter name, the parameter name will be displayed in reverse blue, and the parameter to be set will be switched by rotating the encoding potentiometer;After bit selection, the corresponding bit will be displayed in reverse blue, and parameters will be set by rotating encoder;After the setting is completed, long press the key of the encoding potentiometer for 2 seconds or more, and no key operation will automatically exit the setting;All parameters are saved automatically after exiting.Data group function description:10 sets of data groups of M0-M9 can be saved. By default, the data group M0 can be saved. Press and hold the key of coding potentiometer for 2 seconds on any interface to quickly call up the M1/M2 data group, and the serial number of the current data group will be displayed at the interface index;colour: as shownMaterial: plastic+MetalDC converter: Switch power supply, convert AC 100V ~ 220V to DC 24V.Wide input voltage range, steady and precise output voltage.Lack protection, over load protection (105% ~ 150%), over voltage protection (115% ~ 135%).The widely as power supply used for the LED Strips, LED display, poster, industrial plants, etc. IN-DOOR ONLY USE!Input voltage: AC 100V ~ 220V (50 ~ 60Hz)Input voltage: Cold 40A @ 230V AC StartOutput voltage: 24V DCsetting of the output voltage: ± 1%output current: 5Aoutput power: 120Wworking temperature: -40 ~ 65 degrees CelsiusHumidity: 20% ~ 90% RH non-condensingItem size: 16 x 9.8 x 4.2cm / 6.3 x 3.9 x 1.6inBuck Boost Converter: In the power parameter setting interface, select the data group, and rotate the encoding potentiometer to call up the corresponding data group;After the parameters in the data group are modified and exited, the corresponding parameters will be stored in the current data group by default.Set voltage U-SET:0.6-36V;Set current I-SET:0-5.1A;size: 79 x 42 x 22MMPackage Contents:1 x Buck Boost Converter1 x DC converterNote: power output is off by default after data group switching;Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
