Description
1
Inhibit/Fault
Reset
(input)
Low = RUN, <0.3V
High = OFF, +5V to
+15V
This pin is the basic ON/OFF control pin for the power
supply. Grounding pin 1 enables power supply
operation if all faults are clear. Ap10 to 15V to
pin 1 prevents the inverter from operating. Optional
High Enable available, contact factory, see note 2.

Over-Temp
Fault
(output)
(optional, see
note 2)
High = safe
operation, +15V
Low = Hot warning,
<0.5V
Indicates an internal high temperature condition. When an over
temperature fault occurs, the signal is pulled either to GND or
15V/5V based on specific customers’ requirement. Please
refer to the test data sheet for a specific power supply to see
how that unit is configured. A N/O (a N/C switch is available)
thermal switch closes during an over temperature condition.
Under normal temperature conditions, the over temperature
output is pulled to 15V via a 4.99k resistor. For a 5V interface,
a 2.49k resistor is in parallel with the thermal switch. The
thermal switch will reset itself when the temperature has been
reduced by approximately 20˚C.

No connect
Optional, may be used for customer specified
functionality, see Note 2.

Voltage
Program
(input)
0 – 10V =
0 – Vout
max
Output is programmed externally with a 0 to +10V signal for 0
to Voutmax. See note 1.
Note: Accuracy and linearity will be
compromised when operating below 20% of the max value.

OVERLOAD / NO
LOAD STATUS
INDICATOR
(output)
High = OK, +15V
Low= Overload,
<0.5V
When the output is open or shorted circuited, or if the capacitor can’t be
fully charged to the programmed level in a given time, the Over-Load
Fault will latch Low and the power supply will shut down to protect
itself. Typically, it is 15V at an open collector with a 4.99k pull up
during normal operation. To Clear the Fault: Correct the problem at the
load and toggle the Inhibit signal or recycle the AC input.

Vout Peak
Hold
(output)
0 – 10V =
0 – Vout
max
Peak detect circuit of the output voltage monitor. The
time constant is approximately 5 seconds. See note 1.
8
Vout Monitor
(output)
0 – 10V =
0 – Vout
max
Monitors output voltage. See note 1.

+15VDC for customer interface, maximum output
current is 100mA.

End of Charge

Indicator
(output)
High = Charging,
+15V
Low= Load charged
to Voltage
Program, <0.5V
When the load capacitor is fully charged to the programmed level, the
EOC signal will go Low thru an NPN transistor. The signal is Normally
High via a 4.99k pulled up to 15V. The EOC signal will toggle when the
power supply is refreshing the load cap. Latched EOC is optional: The
EOC signal will latch Low when the capacitor is fully charged and stays
Low until the cap is discharged and the Inhibit signal is asserted.
14, 15
Ground
(output)
Ground return for control interface signals.
