Control and supervisory functions
Bias Supply H
Isolated 5V bias suppl(Pin 1)
to power system control circuitry.
PFC Fail L
A failure in the Power (Pin 2)
bus, is indicated by this open collector signal, asserted low.
Bias Return L
Return path for the 5V bias supply. All signals are referenced to this return.
(Pin 3)
Remote Inhibit H
The output is inhibited when this signal is tied high. IIL max. = 10mA.
(Pin 4)
Voltage Trim
The output voltage ca(Pin 5)
resistor between pin 5 and pin 14.
Current Monitor
Value: 0.1 x Iout. Tolerance: 10%. Range: 5 to 25A
(Pins 13, 14)
Power Good L
An open collector sig(Pin 15)
deasserted: 56.5 to 58V. See Figure 1.
Fan Fail Detect L
An open collector signal, asserted low, indicates fan failure. See Figure 1.
(Pin 16)
Power Fail Detect H
(Pin 17)
An open collector signal, asserted high, indicating AC line failure. The output
voltage will stay within regulation 4ms after PFD is asserted.
Protection features
Overvoltage protection
The unit will shutdown and latch off if the output voltage exceeds the OVP
threshold. Input power recycling is necessary to restart the unit.
Overcurrent and short circuit protection
The unit is protected against an overload on its output in the range 25 to 30A,
with automatic recovery on overload removal. Under short circuit conditions,
the unit shuts down.
Over temperature protection
If the internal temperature of the unit exceeds a safe limit, the unit shuts down
and will need power recycling to re-start.
Input voltage sags
A user supplied jumper inhibits operation of the unit in the 110V range. This
limits the input current to a safe level when operating at 230V to prevent
circuit breakers tripping under brown out. This programmable jumper can be
accessible by removing the cover plate. Refer to view A on page 102.
Load sharing
The DPF1000-9617PE power supply provides load sharing capability for
implementing parallel operation. An internal OR-ing diode is used in each
output to provide N+1 redundancy. The power supplies will share the load
current within ±10% from full load down to
1
/
3
of the rated current of each
power supply.
Method of current sharing of -48V output shall be via the "droop method", as
illustrated in Figure 2 below:
