Introduction

Introduction
The Power Supply Interface Module (PSIM) is part of the
Orbit Measurement System. The PSIM provides local
power to the network when required. Example uses:
• Power via the communications cable is not sufficient
due to cable voltage drops.
• The controlling computer is not suitable to supply the
Orbit Network.
• An RS232 Interface Module is used to control the
Orbit Network.
Note:
Throughout this manual the Orbit System is referred to as requring a 5V power supply. For any applications, actual
voltages or power supplies may be within the 4.75 to 5.25V range according to configuration. PSIM-AC and PSIM-DC
has a nominal 5.1V output no load voltage. This allows for voltage drops across cables when Orbit Modules are added.
