Examples
Example 1:
Using a Model 2611 to charge a 5V battery with 1.5A, while operating at 50°C
ambient temperature; what is the maximum duty cycle?
Assuming the 20V range will be used to measure the voltage:
Example 2:
Using a Model 2602 to pulse 10A of current from a bias level of 500mA, into a
very low impedance (100 mΩ), while operating at 40°C ambient temperature;
what is the maximum duty cycle?
Assuming the 1V range will be used to measure the voltage:
Example 3:
Using a Model 2612 to charge a 12V battery by sourcing 100mA and then
discharging the battery by sinking 5A, while operating at 35°C ambient
temperature; what is the maximum duty cycle?
Assuming the 20V range will be used to measure the voltage:
