Zhiyu® Dc 3.5-15v 0.1-3.0a 18w Usb Fast Charge Quick Charge Tester Adjustable Constant Current Load Qc2.0 Qc3.0 Mtk Pe+ Wide Voltage Design Tl431 Standard Low Temperature Drift

Description: Support 3.5-15V wide voltage test Trigger can do voltage extraction test and automatic test for QC2.0-12V QC3.0 and MTK-PE+. Board LED can indicate voltage in separate parts and the tested voltage rough value can be known visually. TL431 standard; the sampling resistance is manganin resistance; high current stability; low temperature drift. It can be mA adjustment by using multi-circle precise adjustable resistance controlling current. Index Parameter: Test Voltage Range: DC 3.5-15V Test Power: continuous maximum power is 18W; short time power is 25W (after work for 15 seconds, have a break for 30 seconds) Current Adjustment Range: 0.1-3.0A (the lowest current is affected by its own losses; generally start at 0.08-0.13A) Trigger Instructions (Factory Default: QC Manual Test Status): QC Manual Test Status: default is QC2.0-5V after the startup; in starting trigger process, LED changes; it will stay on 5V indicating status (No. 1-2 led lights up); it can switch between 5V, 9V, and 12V by pressing + - button; the indicator light indicates the respective status; if the actual output voltage is not in accordance, the indicator light will flash. Long-press button + (ADJ) and three LED lights flash three times to come into QC3.0 mode; after that, press + button to go up 0.2V and press button to go down 0.2V; LED indicates the respective output voltage segment. MTK Mode: press +- button to go up and go down voltage after the startup; LED only matches voltage segment. Note MTK mode and the voltage switches by current trigger; it takes 2.5 seconds modifying voltage; LED indicates "modifying" ; because it needs current trigger, the current should be adjusted to 0.5A or higher before using MTK mode to modify the voltage or you will fail to modify. Automatic Mode: automatic QC2.0-12V mode and automatic MTK mode; both are automatic cycle switching voltage; at the same time LED displays voltage segment; QC2.0 mode is 5V, 9V, 12V, and 5V cycle switching; automatic MTK mode is 5V, 7V, 9V, 12V, 5V, 4.8V, 4.6V, 4.4V, 4.2V, 4.0V, and 5V cycle switching. Mode Modifying: keep pressing + (ADJ) button; power up the load; three LED flashing at the same time stands for coming into mode setting status after it being powered up; release the button; the indicator light indicates the current mode; QC2/3 light stands for QC mode; MTK light stands for MTK trigger mode; at the same time AUTO light flashing stands for starting the respective automatic test mode; press - (OK) button after the setting to save the test and come into work. Package included: 1 x USB fast charge tester Type A: with trigger Type B: without trigger
