PSIM-AC PSIM-DC PSIM-5V

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.

1.0: Introduction

This Manual

The manual describes the three types of PSIM.

Technical specifications, safety information and

application notes are detailed for each type.

PSIM-AC

Universal mains input to regulated 5V output.

10 - 30 Vdc input to regulated 5V output.

5 Vdc input (from user regulated supply).

PSIM-AC

PSIM-DC

PSIM-5V

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.
