Configuring the KHA3000
Output current limit of the AC power supplies
The maximum rated current of this product is 20 Arms (continuous).
We recommend that you use the current limit feature on the AC power supplies to prevent the
test circuit from overheating due to overcurrent and to protect the EUT. The overheat protec-
tion of this product shuts off the current if the internal resistive element heats up due to over-
current.
Power level supplied from the test circuit to the EUT
With the test circuit common to single-phase and three-phase, the 1P2W power will be one-
third that of three-phase power. Likewise, the 1P3W power will be two-thirds.
Example: If the three-phase power is 6000 W, the 1P2W power will be 2000 W, and the
1P3W power will be 4000 W.
Configuring the KHA3000
For three-phase three-wire circuits
p.70
When used in a three-phase test circuit, the KHA3000 voltmeter is designed to be used in a
three-phase four-wire system. To use it in a three-phase three-wire circuit, you can use the
delta transformation feature of the KHA3000, rather than changing the actual wiring. The
delta transformation feature is used to convert phase voltage measurements to line voltages.
For the setup procedure, see “Delta transformation (star-delta transformation)” in the appen-
dix.
CAUTION
• To ensure safety of this product and EUT, set the output current of the AC power supplies to
20 A or less. Set a current limit on the AC power supply output to prohibit the output from
exceeding 20 A.
