MakerHawkMakerHawk Electronic Load Tester - USB Load Tester 150W 200V 20A Resistor Adjustable Constant Current Battery Capacity Tester Module Intelligent Dischar
Main highlights- Voltage measurement range: 0.00V ~ 200V, Current measurement range: 0.00A ~ 20A.
- Two power supply methods: 1. DC6-12V DC5.0 power supply; 2. DC6-12V Micro USB power supply.The body discharge power cannot exceed 150W, otherwise there is a risk of burnout.
- Prevent burning warning: when the input voltage battery and large power test, access must be beforeusing two current adjustment knob counterclockwise to the minimum to zero, then the access, accordingto the priority according to current power to slowly adjust current knob, must not instantly transferred infull, so there are excessive instantaneous power load discharge tube burnt huge risk! Please use thespecial attention to this point, thank you!
- How to operate: Set the capacity, power, time using the Keystrokes method Reset:1. Reset button Long all data (mAh, Klitschko, 00: 00: 00); 2. Fast button twice capacity reset (mAh); 3. Fast button three power reset (ㅁ);4. Fast button Four time reset (00:00:00); 5. Fast button five settings auto standby, Discharge count down regularly; 6. No load output No load, fast seven key, And current zero zero current, Environmental temperature Accurate calibration.
- 150W power refers to: In accordance with the power calculation formula P = UI (power = voltage x current); 10V input Approximately 18A discharge current 20V input Approximately 9A discharge current 30V input Approximately 6A discharge current.
