Appendix A 43
A
100 VAC Input Power Option 100
General Information
Description
Option 100 is a modification of the power supply that involves changing the values of resistors located in the Overvoltage
Protection and Power Limit Circuits. It also entails recalibrating the unit and changing the Front Panel. These changes allow
the unit to operate at a lower line voltage of 90-105 Vac, while operating on the same line frequency of 48-63 Hz. The
reduced input voltage limits the output power, while retaining the standard unit’s output current rating. Other parameters
that change due to Option 100 include the Overvoltage Trip Range and the Remote Analog Programming Specification.
Scope of Appendix A
This appendix contains all the information necessary to support the power supply when it is equipped with Option 100. The
appendix describes only the changes pertaining to Option 100 and how they affect the other portions of this manual. Unless
otherwise specified in Appendix A, all other portions of the manual apply to both the standard supply and Option 100
supply.
Using Appendix A
The Option 100 changes are listed sequentially, starting with Section 1 in the main body of the manual and working back
through Section 3. It is recommended that the user mark all the necessary changes directly into the manual using Appendix
A as a guide. This will update the manual for Option 100 and eliminate the need for constant referrals back to Appendix A.
Section 1 Manual Changes
In Section 1 change the following values in Figure 1-1.
