Test Load Configuration
RECOMMENDED TEST LOAD
For setup and configuration, we recommend using a test
load in place of the Thermoelectric Cooler (TEC) or resistive
heater, connected directly to Pin 9 and Pin 13 on the
controller, as shown in
NOTE:
Use a max of +5 V power supply with the test
load shown. Values shown can simulate any load up to
the WHY5640 maximum of 2.2 A. Always check the
before operating the WHY5640 controller.
