Product Description
Yeeco 15W Adjustable USB Load Tester Board, DC 3-21V 3A Load Battery Tester, Constant Current Load Discharge, Electric Resistance Resistors for Power Monitor Mobile Charger Tester with Heatsink Fan
- DC 3.5-21V operating voltage; 0-3A continuously adjustable constant current discharge;15W Max discharge powe USB load tester
- Compatible with Qualcomm QC2.0 high pressure discharge load; with wiring TERMINAL which is reserved for DIY project
- Double side insert design DC 3-20V USB input; vertical female USB seat is reserved for continuous current
- Double metal knobs, one for current trimming +/-0.2A; the other for current 0-3A coarse adjustment
- Great heat dissipation: Copper double side porous heat sink and intelligent cooling fan
This DC adjustable 0-3A USB dummy load apply to most products with USB output interface
Operating voltage: DC 3-21V(compatible with Qualcomm QC2.0 A/B protocol 5V/9V/12V/20V)
Constant current discharge: 0-3A continuously adjustable (current trimming +/-0.2A; current 0-3A coarse adjustment)
Current Operating Error: less than 2% + 3mA
Continuous Discharge Power: 15W / can reach 25W in short time (When at DC 20V high voltage, please try to keep the constantly discharging current less than 1A in order to avoid causing a heavy load on the discharge tube because of the high power)
Intelligent temperature control: 55℃(the fan will work automatically when temperature is higher than 55℃)
Type of intelligent temperature control sensor: NTC High sensitive thermistor
On/off switching frequency of the fan's chip DC-DC chip: 1.2MHz
Dual input interfaces' mode: USB input/ 3.5 pitch screw pressed wiring column
Power Indicator: Blue LED
Fan Speed: 2900/min
Type of Discharge Power Tube: Low resistance & Temperature resistance, MOS Field-Effect transistor (The constant current is more stable in high pressure and high temperature)
Package include:
1x15W USB Load Tester
