Features: 1. High precision 4-digit LED digital display, intuitive and clear. 2. Intelligent fan, excellent heat dissipation, effectively extending fan life and reducing noise. 3. Using advanced technology, it effectively reduces the weight of the power supply and facilitates power supply movement. 4. Multiple protection functions, over current protection (OCP), over temperature protection (OTP), over power protection (OPP). 5. Plastic panel, more beautiful. 6.Adjustable USB output Output Power: 160W Power Supply Voltage: 220V ??10% 50Hz or 220V ??10% 60Hz Export voltage: Continuously adjustable from 0 to 30V (resolution is 0.01V) Voltage export accuracy: ??0. 02V Recovery time: 100uS Constant current value : 0~5A Constant output current : Continuously adjustable from 0 to 5A (resolution is 0. 0001A) OCP current value: 0-5A Accuracy: ??0. 01A Signal test frequency range: 30~1800MHZ including cell phone signal test Product Features : Double Digital Display 1. Ring Transformer: working for a long time 2. Temperature-sensitive Cooling Fan: automatically activates the fan function when the components temperature is too high. 3. 4 Memory Modes : M1, M2, M3, M4 4 memory modes, save the records(current/voltage) by setting. 4. Orange Bottons: current/Voltage protection function, continuous overcurrent protection and once overcurrent protection, press and hold one of them to make the corresponding lamp (CONT. OCP or ONCE. OCP) lights up to work. 5. Double modes to adjust current and voltage: <1> Normally twist V/A knob keys to adjust current and voltage; <2> When you need to quickly adjust larger or smaller current or voltage, long press 3 seconds current or voltage button to make the number jump and then knob directly to adjust the digital current or voltage you want. 6. USB output: Adjust the current and voltage you want in the same way as above when connecting via USB. Package Content* 1x ABEST search 3005D Power Supply 1x User Manual 1x Magnetic Mat 1x Power Cord
