TM 503
OPERATING
INSTRUCTIONS
INTRODUCTION
Description
The TEKTRONIX TM 503 Power Module is a three-
compartment-wide mainframe for the TM 500 Series of
Modular instrumentation, It accepts up to three independ-
ently functional plug-in modules to form a compact,
versatile and low cost instrumentation system. The TM 503
is a basic power source and provides an interconnecting
scheme for the other members of the TM 500 Series family.
Factory options allow customer modification using signal
access at the plug-in module/power module interface to
provide rear panel inputs and outputs, and interconnections
between compartments.
Power Source
This
instrument
is
designed
to
operate
from
a
power
source
with
its
neutral
at
or
near
earth
(ground)
potential
with
a
separate
safety-earth
conductor.
It
is
not
intended
for
operation
from
two
phases
of
a
multi-phase
system,
or
across
the
legs
of
a
single-phase,
three-wire
system.
Power Usage
With three plug-in modules installed, the TM 503 can
require up to 120 W of power at the upper limits of the
high fine voltage ranges. Actual power consumption
depends on the particular module combination and
operating mode selected at any one time.
Operating Temperatures
The TM 503 can be operated in an ambient air
temperature of O°C to +60°C. Thermal cutout devices
protect the system by disconnecting the power to the TM
503 Power Module when internal temperatures rise above a
safe operating level. These devices automatically return
power to the unit when the internal temperatures return to
a safe level.
Since the TM 503 can be stored in temperatures between
—40°C and +75°C, allow the instrument's chassis to return
to within the operating limits before applying power.
POWERING UP
Plug-in Modules
it is not necessary that all the plug-in compartments be
utilized in order to operate the Power Module. The only
modules needed are those necessary to accomplish the task.
CAUTION
re PPPS
LARA)
Turn the Power Module off before inserting the plug-
in; otherwise, damage may occur to the plug-in
circuitry.
Module Installation
1. Check the location of the white plastic barriers on the
interconnecting jack to insure that their locations match
the slots in the edge of the plug-in module’s circuit board.

2. Align the plug-in module chassis with the upper and
lower guides of the selected compartment. Push the module
in and press firmly to seat the circuit board in the
interconnecting jack. (Remove the plug-in module by
pulling on the white release latch located in the lower left
corner of each module.)
3, Pull the PWR button on the left side of the TM 503.
Some plug-in modules have independent power switches,
usually labeled OUTPUT, controlling application of main-
frame power to the module itself. Push this button to
activate the plug-in module.
Loading Considerations
With three plug-in modules installed, the TM 503 can
require
up
to
120
W
of
power
from
