battery will power the device for up to a half an hour in the absence
of power. This battery has a design life expectancy of more than 2,000
charge/discharge cycles.
The Power Supply port, as shown in Figure 7, contains 3 terminals on a removable/

to 300 V
RMS
AC or DC (42-69 Hz for AC
sources).
The supply current is power factor corrected and the maximum power consumption
of the Vecto III is actively limited to 12.5 VA. The Vecto III can be powered directly from
110 V 50/60 Hz VT circuits due to this low burden.
The power supply is protected from brief periods of overvoltage conditions by built-in
surge protection.
