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.
