Product Description 4-Wire 150W Battery Capacity Tester Electronic Load Power Discharge USB Tester Attention: - Batteries are not included. - Exceeding the specified power, the product will be burnt out. - 150W power means: according to the power calculation formula P = UI (power = voltage x current). - When inputting 10V, discharge current is about 18A. When inputting 20V, discharge current is about 9A. When input 30V, about 6A discharge current. Product Description: This electronic load can measure the voltage, current, power, capacity, power and discharge time of various batteries (batteries are not included), DC power supplies, data lines, power banks, chargers, and AC/DC power adapters, internal resistance, load capacity and other properties. Its function is more than that of electronic load meter of hundreds of US dollars, and its volume is relatively smaller. It is more more flexible to use. Thanks to its lower price, it is very suitable for manufacturers to verify, intimate instruments for digital enthusiasts, engineers and other experiments. Features: - 2.4-inch HD large color screen blue digital transmission curve version high-power tube digital load meter. - Support discharge aging test, which can be used to test the voltage, current, power, capacity, electricity, temperature, discharge resistance, time-limited discharge settings, stop voltage setting and other parameters and operation of various power supplies such as USB chargers, mobile power banks, battery and battery capacity, power adapters, etc. - Support Bluetooth wireless connection and wired computer connection modes. - Support four kinds of online APP (support for Android, Apple, PC computer Bluetooth wireless online APP and data wired online APP) - Four discharge modes: constant current, constant power, constant resistance, constant voltage. - High-power and large-discharge tube discharge test is used internally, summarizing the principle and evolution of hundreds of large-scale instrumentation circuits, integrating all major advantages in one, and displaying a variety of parameters on the screen of discharge aging, convenient and fast test, and powerful function! - 150W high power; 200V wide voltage; 25 high current. Strong performance, can be used for various discharge and aging detection. - 4 Operating Modes: CC-constant current operation; CV-constant voltage operation; CW-constant power operation; CR-constant resistance operation. - Intelligent temperature control fan: high-power, long-life cooling fan. Technical Parameters: - Test voltage: 2~200V - Working current: 0.2~25A - Constant load adjustment rate: +/-3%+3 bytes - DL24 discharge power: voltage x current <150W - DL24P discharge power: voltage x current <180W Attention: - Actual operable current is limited by the maximum power. Please follow the law of conservation of energy to adjust current. - Built-in over current, over temperature and over power safety protection functions. If the protection interface pops up, please pay attention to the parameter adjustment. To adjust to the maximum power discharge, you can first slowly adjust the preset value and smooth the adjustment in the open discharge, so as to achieve the adjustment to the maximum power discharge.
