Single-phase, Three-wire Operation
In single-phase, three-wire operation, the control panel display differs from that
when a PCR-LA power supply is operated singly.
Operation procedure
■
Operation of the Output Terminal
1.
Turn the SYSTEM POWER switch OFF.
The WIRING switch can be operated only when the SYSTEM POWER switch
is OFF.
2.
Press the WIRING switch’s 1P3W button.
The 1P3W lamp lights up.
3.
Turn the SYSTEM POWER switch ON.
■
Operation of the PCR-LA power supply (U-phase unit)
For details, see the PCR-LA AC Power Supply Operation Manual. The basic
operations are the same as those for single-phase parallel operations. Note that
in single-phase, three-wire operation, a voltage display can be selected as
described below.
4.
Press the PHASE (SHIFT, 2) key to display the line voltage.
The value displayed is approximately twice the phase voltage
5.
Press the PHASE (SHIFT, 2) key again to display the phase voltage.
This causes the display voltage value to return to the original indication (phase
voltage display).
Display common to each phase
The three-phase symbol
and the letter “U” or “V” appear at the left of the
voltage display area. In this case, the letters indicate that the PCR-LA power
supplies have been set to their respective phases. The voltage display value set
at factory shipment is the phase voltage.
If the letters U-V are displayed at the left of the voltage display area, the PCR-
LA power supplies display the respective line voltages.
V-phase unit display
The control panels display only the phase (V) indication, voltage and current
indications, and the load level meter.
U-phase unit display
When the three-phase symbol
and all of the letters “U” and “V” appear at
the left of the current display area during power display, the total power of the
single-phase three-wire is indicated.
If the three-phase symbol
and the letter “U” or “V” appear at the left of the
current display area during a self-test, the U-phase power supply displays the
self-test results for each indicated phase.
