Status and Control
Signal Definitions
All signals and outputs are referenced to Output return. These
include ‘Vstb return’ and ‘Signal return’.
Input Signals
Voltage programming (V
prog
): An analog voltage on this signal
can vary the output voltage from -42Vdc to -58Vdc. The
equation of this signal is:
V
out
= 20x (V
prog
) 2.1 < V
prog
< 2.9
If Vprog is ≥ 4V, or left open the programming signal is ignored
and the unit output is set at the setpoint of -54Vdc.
Load share (Ishare): Single wire analog signal between power
supplies connected in parallel. The Ishare pins should be tied
together for power supplies. No resistors or capacitors should
get connected to this pin.
Remote ON/OFF: Controls the presence of the main -54Vdc
output voltage. This is an open collector, TTL level control
signal. This signal needs to be pulled HI externally through a
resistor. Maximum collector voltage is 12Vdc, maximum sink
current is 1mA. Logic 1 turns ON the -54Vdc output, while a
Logic 0 turns OFF the -54Vdc output.
A turn OFF command either through this signal or firmware
commanded would turn OFF the -54V output.
Enable: This is a short signal pin that controls the presence of
the -54Vdc main output. This pin should be connected to
‘output return’ on the system side of the output connector. The
purpose of this pin is to ensure that the output turns ON after
engagement of the power blades and turns OFF prior to
disengagement of the power blades.
Write protect (WP): This signal protects the contents of the
external EEPROM. When left open the EEPROM is write
protected. A LO permits writing to the EEPROM. This signal is
pulled HI internally by the power supply.
Output signals
Output current monitor (Imon): A voltage level proportional to
the output current is present on this pin. The signal level is
0. 2V per amp ± 0.25V.
AC OK: TTL compatible open collector. Maximum sink current
20mA, max voltage is 12Vdc. A (HI) on this signal indicates
that the input voltage is present within limits.
DC OK: TTL compatible, open collector. Maximum sink
current 20mA, max voltage is 12Vdc. A (HI) on this signal
indicates that the output voltage is present.
Over temp warning: TTL compatible, open collector.
Maximum sink current 20mA, max voltage is 12Vdc. A (HI) on
this signal indicates that temperatures are normal.
If an over temperature should occur, this signal would delay
pulling LO for approximately 10 seconds. The unit would
restart if internal temperatures recover within normal
operational levels.
Fault: TTL compatible, open collector. Maximum sink current
20mA, max voltage is 12Vdc. A (HI) on this signal indicates
that no faults are present.
This signal activates for OTP, OVP, or AC fault.
PS Present: Connected to ‘output return’. Its intent is to
indicate to the system that a power supply is present. This
signal may need to be pulled HI externally through a resistor.
Interrupt: A TTL compatible status signal, representing the
SMBusAlert# feature of the i 2 C protocol in the power supply.
This signal needs to be pulled HI externally through a resistor.
Maximum sink current ≤ 4mA and the pull up resistor should
be tied to <5Vdc. Open collector (HI) on this signal indicates
that no Interrupt has been triggered.
