Inspection and Installation
1. Remove the output terminal cover.
2. Connect the Vo+ and Vs+, Vo- and Vs- for short circuit using the short clips
on the back panel of the instrument or electric wire. When using local sense,
the remote sense terminal cannot be disconnected.
Do not disconnect the wires if remote sense is not used. Doing so will
cause erratic behavior and may damage the power supply under certain
conditions
3. Loosen the screws of the output terminals and connect the red and black
test cables to the output terminals. Re-tighten the screws.
When maximum current that one test cable can withstand fails to meet the
current rated current, use multiple pieces of red and black test cables. For
example, the maximum current is 1,200 A, then 4 pieces of 360 A red and
black cables are required.
4. Install the output terminal cover.
5. Directly connect the other end of the red and black cables to the DUT.
Remote Sensing
If the tested instrument consumes large current, a large voltage drop will be
detected in connection line between tested instrument and power supply
terminal. To ensure measurement accuracy, a remote sense measurement
terminal Vs+ and Vs- are provided at power supply rear panel to compensate
voltage drop lost in wire.
When the power supply is used for measuring battery charge in actual
applications, the voltage drop of the wire will lead to voltage inconsistency of
both ends and inconsistency of the cutoff voltage of power supply and the
actual voltage of battery, resulting in inaccurate measurement.
The sense terminal of rear panel diagram as follows:
The connection diagram and steps of remote sensing are as follows:
