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.
LDN-PS 3M-3340/1206
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.
2.0: Safety Information PSIM-AC PSIM-DC PSIM-5V
LDN-PS 4M-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.

4.0: PSIM Schematic and Pin-out
The 5V power supply line from the network is isolated at the PSIM.
All modules before the PSIM are powered from the network. Example: Orbit Network Card.
All modules after the PSIM are powered from the external power supply connected via the PSIM. 0 V is common.
