Test Procedure Summary
4.1
Equipment
The following sections outline the equipment necessary to perform all tests in the test procedure.
•
Power supply #1 (PS #1) capable of supplying 12 V at 3 A is required
•
Power supply #2 (PS #2) capable of supplying up to 5 V at 5 A is required to power battery emulator.
•
PR1010-002 (Battery emulator)
•
Flat-head screwdriver
•
Three voltage meters (VM) and two equivalent current meters (A) are required. The current meters
must be able to measure 3-A current.
4.2
Equipment Setup
1. For all power connections, use short, twisted-pair wires of appropriate gauge wire for the amount of the
current (can handle 3 A).
2. Set PS1 for 5-V, 2-A current limit and then turn off supply
3. Connect the PS1 in series with current meter (A1) to J1 (DC+ and DC–).
4. Connect a Voltmeter (VM1) across DC1 and DC2.
5. Adjust PS2 set to approximately 3.6 V with current limit of 4 A to the input side of battery emulator,
then turn off PS2.
6. Connect VM2 across J2 (OUT, GND)
7. Connect the output side of the battery emulator in series with current meter (A2) to J2 (OUT and
GND).
