GENERAL DESCRIPTION
The MicroPak TM Controller, in conjunction with
an appropriate cascade, is used to provide high
voltage for electrostatic application equipment.
The controller is packaged in a single, 3.2 inch
wide Eurocard module, and thus consumes less
than 1/4 of the available space in a 19 inch rack.
The MicroPak uses a combination of proven high
voltage generation technology including micropro-
cessor-based control with diagnostic and commu-
nication functions. The processor circuitry provides
the maximum in applicator transfer efficiency, while
maintaining the maximum safety when used in
conjunction with FM listed applicators.
SAFETY FEATURES
When used with FM listed applicators, the Micro-
Pak provides the ultimate in operational safety.
The microprocessor circuits allow the use of output
load curve control, which limits the high voltage
output to safe levels, even with the controls set at
maximum levels, and does so without a hard shut
down. The Over current set point, which can be
monitored on the µa Display by pressing the SET
push-button and holding for one second, does pro-
vide a hard shutdown if the output current exceeds
the set point. The kV set point is also displayed
on the kV display when the SET push-button is
pressed for one second.
DISPLAYS
The front panel displays for output voltage and
current indicate the outputs from the cascade of
direct charge applicators or the probe tip voltage
in the case of indirect charge applicators. They are
derived from feedback signals in the low voltage
cable between the controller and the cascade.
Temp. Operating: (0 o to 55 o C)
Storage: (-40 o C to 85 o C)
Humidity: (95% Non-Condensing)
Size: 100 X 160mm
Eurocard module,
total width 3.2 in.
(one module)
In RansPak TM 1000 mode, beginning with software
version 3.2, the signal used for the current (µA)
display is conditioned to subtract out the internal
cascade “bleeder” current and thus display the
actual output current.
Note: 24 VDC and 28 VDC power supplies must
be regulated and have overcurrent (40%) and
overvoltage (20%) protection.
