Alinan 2pcs ZK-4KX DC DC Buck Boost Converter Variable Voltage Regulator CC CV 0.5-30V 4A 5V 6V 12V 24V Power Module Adjustable Voltage Regulated Laboratory Power Supply

Feature: Input Voltage: 5.0-30v Output Voltage: 0.5-30v Output Current: can work stably at 3A for a long time, and can reach 4A under enhanced heat dissipation Output Power: natural heat dissipation 35W, strengthen heat dissipation 50W Voltage Display Resolution: 0.01V Current Display Resolution: 0.001A Conversion Efficiency: about 88% Soft Start: yes (with high power and load module may fail when starting) Dimensions: 79mm*43mm*26mm(L*W*H) Protection Mechanism: Input anti-reverse connection Output anti-reverse irrigation Input undervoltage protection (4.8-30v adjustable, default 4.8v) Output overvoltage protection (0.5-31v adjustable, default 31V) Output overcurrent protection 0-4.1a (adjustable, default 4.1a) Overpower protection (0-50w adjustable, default 50W) Overtemperature protection (80-110? adjustable, default 110?) Timeout protection (0-100h adjustable, off by default) Super capacity protection (0-60ah adjustable, off by default) Operating Frequency: 180KHZ Note: LUP -- undervoltage protection threshold OUP -- overvoltage protection threshold OCP -- overcurrent protection threshold OPP -- over power protection threshold OAP -- ultra-capacity protection threshold OHP -- timeout protection threshold OTP -- overtemperature protection threshold Short press rotate encoder to select which bit you want to set the protection parameter.Long press the rotary encoder to set the protection parameters on or off (only timeout protection and supercapacity protection can be set to turn on/off, and other protection parameters are turned on by default.).Rotate the encoder left and right to make the parameters bigger and smaller.After setting, long press U/I to return to the normal interface.
