Orbit Network Power Supply Requirements

All Orbit Modules are designed to work from a supply

voltage of 4.75V to 5.25 Vdc. When power is applied to

a module its current consumption will cause a slight

voltage drop across cables. Care must be taken to

ensure that all modules have the right working voltage

applied.

This section is for guidance only. Since every application

is different, it is not possible to give precise information

that covers all installations.

Your original supplier will be able to provide further

advice, if required.

7.0: Applications

Orbit Network Protection

Each PSIM provides a high level of protection for an

Orbit Network. Protection for mis-connection, over

voltage and transients is provided.

If a transient or other over voltage occurs, the protection

circuits will short circuit (crow bar) the power supply. At

this time, the voltage levels to each Orbit Module will be

below the working limit. When the fault condition has

been removed, Orbit power must be removed and re-

applied to allow a full hardware reset to take place. A

software reset is not possible under these conditions.

PSIM-AC PSIM-DC

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.
