DESIGNATION
Module's internal temperature test point.
TEMP Test point By default the pin is unconnected, but can
be activated on request.
PINS 2,4,5,6 are connected to the circuit
ground of all internal circuits. The return
Ground
signal connection for all interface signals
should be made to one of these pins.
A positive DC voltage applied to this pin
controls the output voltage set point.
Voltage Program
0-10V corresponds to 0-V
The high voltage output is inhibited or
enabled by this pin
INHIBIT
0V – enabled; 5V or free-standing –
inhibited
This pin is pulled to the ground, when the
output voltage is equal to the program
Ready Indicator
voltage (or higher than the program
voltage)
These pins provide +15V DC that may be
used for status LEDs etc.
+15 V
Maximum output current 40mA
This pin provides +5V DC that may be
used for status LEDs etc.
+5 V
Maximum output current 40mA
N/C -
This pin is pulled to ground when some
failure occurs.
voltage output will be also disabled.
Failures:
Overtemp
(Fault Indicator 2*)
This Fault indicator is also pulled to the
ground on start-up of PCA. In 2-5s, once
the start-up sequence is performed
completely, the signal is automatically
removed.
This pin is pulled to the ground when
overvoltage occurs.
Overvoltage
overvoltage, the high voltage output will
be also disabled.
PIN15 is pulled to
End of Charge output voltage is below the program
Indicator voltage.
Otherwise PIN15 is pulled to +15V.
The HV OUTPUT is inhibited (when
+15V is applied) or enabled (when 0V is
applied or the pin is free-standing). This
Secondary Inhibit
pin should be used only to control parallel
operations of two or more power
modules.
