4.2 More Modes

To meet various test requirements, UTL8500 series electronic load offers more test modes
for choice, including Dynamic, List, Dual, OCP/OPP, CR-LED, Battery, Load Effect, OVP,
Short Circuit, Time and more, as shown in Table 4-2.
More Modes
Two different voltage/current values are set. The load will switch between
Dynamic
these two values when testing.
Up to 16-step different loading modes can be set. It can customize the
List stepping mode and the upper and lower limits of test and judgment, and
have the function of saving and memorizing for each group of test modes.
Two constant test modes combine to form a dual on-load mode, including
Dual
CR+CC, CV+CR and CV+CC.
Set the overload current/power/voltage value to identify whether the
protection function of the tested object is normal. The load continuously
OCP/OPP
increases the set load value during the test, and detects the value of the
tested object when performing the protection function.
The test mode is for LED power supply, which can simulate the operating
CR-LED parameters (voltage/current and LED coefficient) to measure the
performance of LED power supply.
Discharge the measured battery by CC/CR/CP mode. The test will end
Battery automatically when reaching the ending value. The battery capacity and the
discharge graph will also be display.
Load according to three different loads of the set value to calculate ΔV and
Load Effect
Reg (load regulation).
Set the overload current/power/voltage value to identify whether the
protection function of the tested object is normal. The load continuously
OVP
increases the set load value during the test, and detects the value of the
tested object when performing the protection function.
A short-circuited circuit will be simulated in input terminal to test if the
Short Circuit protection function of measured object can work normally when its output
terminal is short-circuited.
For the start/drop time test of the switching power supply, set the start
value and end value of the load. After the voltage of the tested object is
Time
stabilized, the time it takes for the process to rise to the stable voltage is
detected.
