Battery DC Load Tester - USB Interface - Resistor Load Battery Capacity Voltage Discharge Resistance Tester (1A/2A - 2 Mode)
- Buy 100 for ₹90.00 each and save 31%
- Buy 1000 for ₹84.00 each and save 35%
The product is designed according to the principle of ohm's law and through the resistor in parallel and two different switches, the module can provide 2 kinds of resistance for USB power input, when all the switch opens, is 2.2 ohm/10W, 4.7 ohm/5W, 2 kinds of resistance in parallel at the same time, in 5V voltage almost can produce 2A discharge current. The actual current size, please according to ohm's law: I = U/R Resistor in parallel calculation formula: R=1/(1/R1+1/R2+...+1/Rn) K1=4.7Ohm/10W, K2=2.2Ohm/10W
When using this discharge resistor the element reaches a high temperature and hence handles it carefully, do not touch with bare hands. Also, please do not put flammable substances nearby when using it, and avoid direct contact with the heat resistance of the desktop, so as not to scorch the desktop. It's normal when welding resistance may occur heated white smoke or odor phenomenon.
New products can freely be switched with a switch, very convenient, and easy to use. USB load resistance, is mainly to do a discharge test, if the charger or mobile power supply output current is 2A, load meter power is 5V * 2A = 10W, if the output current is 1A, then the power load is 5V * 1A = 5W.
Specification: 1. Voltage: 5V; Use USB power supply more than 2A, do you use a computer USB port to power the device. 2. Max Discharge Current: 2A 3. Rated Power: 5W (5V 1A) and 10W (5V 2A) switchable 4. Resistance material: Ceramic Composition 5. Color: With switch 1A LED glow Green, 2A LED Glow Red
