Ransburg LEPS5001 Power Supply for LECU5003 - Manual (Page 9)

GENERAL DESCRIPTION
The LECU5003 Control Panel and LEPS5001
Power Supply produce 0 to negative 100 kVDC
continuous operating voltage. The two outputs
of the LEPS5001 Power Supply provide spray
devices with up to 2500 microamps at 100 kV.
This heavy duty source of high voltage provides for
rugged, reliable operation in a variety of industrial
finishing applications.
The LEPS5001 Power Supply is Factory Mutual
Approved when used with the LECU5003-01 or
LECU5003-02 Control Panel for Aerobell ® rotary
atomizer and REA III TM automatic systems. Ref-
erence the LECU5003 manual or contact your
local Ransburg representative for more details.
A maximum allowable current level is selected by
the user on the Sensitivity Module located inside
the LECU5003 Control Panel. The Sensitivity
Module circuit determines if the power supply
output current exceeds the desired maximum
current as set on the Sensitivity Module. If so,
the control panel immediately enters an overload
condition which de-energizes the high voltage.
The sense circuitry is sufficient to eliminate most
possible arcing conditions, however, the overload
sensitivity must be properly set as described in
the "Safety Overload Adjustment" section of the
LECU5003 Control Panel manual, to ensure safe
operation.
All components of this power supply were design
selected for reliable, heavy-duty service. The
components, including the high voltage transform-
er, operate immersed in high quality (non-pcb)
dielectric oil to insulate against corona discharge
and provide heat dissipation.
Systems include, but are not limited to the following:
• LEPS5001-02 High Voltage Power Supply
• LECU5003-01 or -02 Control Panel
INTRODUCTION
The LECU5003-01 and -02 Control Panels, when
connected to the LEPS5001-02 Power Supply,
will generate an unregulated output voltage of
up to 100 kV.
• Remote (push-button) ON/OFF Station
• Remote Alarm Bell
• High Voltage Cable
• Air Logic Station
• High Voltage Junction Tank
A high voltage junction tank accepts high voltage
input from one output of the LEPS5001 Power
Supply and provides multiple high voltage out-
puts to supply multiple applicators. Consult the
appropriate junction tank service manual or your
authorized Ransburg representative for further
information.
• High Voltage Switch Tank
A high voltage switch tank provides a means
of discharging residual charge from the appli-
cator(s) when the control panel is turned off or
an overload condition occurs. The switch tank
accepts high voltage input from one output of
the LEPS5001 Power Supply and independently
controls high voltage to two outputs. When the
system is operating normally, the switch tank
passes high voltage from its input to its output.
When the system is turned off or an overload
occurs, the switch tank automatically grounds
the applicator. Consult the appropriate switch
tank service manual or your authorized Rans-
burg representative for further information.
