DCA-150SSJU — CONTROL PANEL
The definitions below describe the controls and functions of
the DCA-150SSJU "
Control Panel " (Figure 8).
1. Main Circuit Breaker – This three-pole, 400 amp main
breaker is provided to protect the UVW voltage output
terminals from overload.
2. AC Ammeter – Indicates the amount of current the
load is drawing from the generator.
3. Ammeter Change-Over Switch – This switch allows
the AC ammeter to indicate the current flowing to the
load connected to any phase of the output terminals, or
to be switched off.
4. Voltmeter Change-Over Switch – This switch allows
the AC Voltmeter to indicate phase to phase voltage
between any two phases of the output terminals, or to
be switched off.
5. Voltage Regulator Control – Allows adjustment of the
generator’s output voltage.
6. Frequency Meter – Indicates the output frequency in
hertz (Hz). Normally 63Hz. with a calibration difference
of +0.5% with the mechanical governor or +0.25% with
the electronic governor.
7. AC Voltmeter – Indicates the single phase output
voltage present at the UVW terminals.
