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.

This equipment is designed as safety Class 1 apparatus

to comply with EN61010-1.

Service Safety

This equipment has been designed and tested to meet

the requirements of the Low Voltage Directive (1997)

and has been supplied in a safe condition. This manual

contains information and warnings that must be followed

by the user to ensure safe operation and to retain the

apparatus in a safe condition.

Terms and Symbols in this Manual

WARNING statements identify conditions or practices

that could result in personal injury or loss of life.

CAUTION statements identify conditions or practices

that could result in damage to the equipment or

other property.

This symbol indicates where applicable cautionary or

other information is to be found.

CAUTION: Power Source. The PSIM-AC unit should

be connected to the mains supply via a suitable lead

with a IEC320 socket. The user should fuse this

connection with a suitable fuse. Refer to Specification.

Apply no more than 265V rms. (AC) between supply

conductors and ground.

WARNING: Do not operate in an explosive

atmosphere.

WARNING: Do not remove covers or panels.

To avoid personal injury, do not remove covers

and panels. Do not operate the equipment

without the covers and panels fitted. There are

no internal adjustments required during the

commissioning of the equipment.

M-3340/1206

WARNING: Danger arising from loss of

ground. During a fault condition and upon loss

of protective ground (earth), all accessible

conducting parts - including controls that might

appear to be insulated - can render an electric

shock.

WARNING: Grounding the equipment. The

unit is grounded through the mains lead: to

avoid electric shock, plug the power lead into a

properly-wired receptacle before connecting to

the input or output terminals. A protective

ground connection by way of the grounding

conductor in the power lead is essential for safe

operation.

2.0: Safety Information (continued)

PSIM-AC PSIM-DC PSIM-5V

CAUTION

This equipment contains no user serviceable parts. This

equipment must be returned to original supplier for all

service and repair. Dismantling the unit will invalidate the

warranty.

CAUTION

To avoid a fire hazard, use the correct fuse type, voltage

and current rating as specified for the equipment. Refer

fuse replacement to qualified personnel.
