SG4000 Installation and Operation Manual
SG4-PS Power Supply
The SG4-PS power supply module is auto-ranging and requires no start-up voltage jumper
selection. The SG4-PS begins to operate when the proper input voltage level of 44 VAC rms is
reached with a line frequency of 50 Hz or 60 Hz. The wave shape of the input voltage must be
quasi-squarewave. The SG4-PS features a self-protection attribute that shuts it down for
instantaneous line voltages higher than 176 VAC. A precision output regulator protects against
overcurrent and short circuits, thus providing a precise output voltage. The SG4-PS does not
have power factor correction circuitry.
Figure 4-9 illustrates the SG4-PS module and the user-related features.

SG4-PS features
Feature Description
AC Test Point
Enables you to verify the presence of AC input voltage to the SG4-PS.
DC Test Point
Enables you to measure the DC output voltage of the SG4-PS. The nominal
voltage is 24.3 V as the test point is located on the anode of a diode.
Power Supply Enable
A green LED (
ON) provides visual indication of the SG4-PS’s enable status. If
the light is not illuminated, the SG4-PS is not producing a DC output.
24.3 V Adjustment
Output voltage adjustment that is factory aligned.
