Determining Application Sizing
STOP!
DO NOT use the instruction manual that came with your
voltage regulator when using the SEM100A Static Exciter Module!
Use this manual instead! It contains the most up to date information
available regarding your product!
The SEM100A Static Exciter Module is designed for use with 208-240VAC input. It contains
internal suppression for use with brush-type generator sets. Before installation, it is necessary
to verify that the SEM100A is the correct product for your application.
To determine if the SEM100A is the correct product for your generator you need to know any
two of the following 3 specifications from the rating plate of your generator:
1: Exciter Field Voltage (in DC Volts)
[Generally given in full load Voltage on nameplates]
2: Exciter Field Resistance (in Ohms)
[See Note Below]
3: Exciter Field Amperage (in DC Amps)
[Generally given in full load Amps on nameplates]
Using the specifications obtained from your generator exciter,
verify that your generator fits the specifications from the chart or
graph below:
•
Exciter full load voltage is 63VDC or less, and your exciter field resistance is
1.05
Ω
or greater.
