High Power DC Electronic Load 63200 Series Operation & Programming Manual
Figure 3-10 Load Surge Capability (Dynamic Mode)
Note 1: The Initial state under Static Mode should last at least 1 second.
Note 2: This load surge capability will be regulated by the temperature de-rating
characteristics. (Refer to Note 1 in Specifications)
Note 3: Examples below assume the use of the Model 63201 load with a continuous rating
of 2600W/300A/1-80VDC.
Example 1:
STATIC LOADING
The Model 63201 can be overdriven to approximately 5200W (200% of its rated continuous
power rating) for 0.06 seconds when the starting power is 650W (25% of its rated power).
This is represented by DOT on the blue curve in Figure 3-9.
Example 2:
DYNAMIC LOADING
The Model 63201 is capable of a zero – to- 6500W (250%) pulse at a duty cycle of 5%.
This is represented by the DOT on the purple curve in Figure 3-10.
3.5.6 Timer Function for Battery Discharge Testing
The 63200 Loads include unique timing & measurement function allowing for precision time
settings and measurements in the range of 1s to 99999s. This feature allows users to set a
final voltage & timeout value for battery discharge testing and similar applications.
For example, Figure 3-11 below shows that the 63200’s internal timer can be initiated
automatically when the battery voltage falls below a preset value. The timer will continue
counting until the second preset voltage value is reached.
