The Red ‘POWER’ LED on the 9017-4001 Power supply indicate that an incoming
supply is present at the unit and could therefore be illuminated whether the
power supply itself was switched on or off.
The Green ‘POWER’ LED on the 9017-4010 however, only illuminates when there is
an incoming supply, the power supply is switched on and the internal control
supply is healthy.
6.2.2. Fast I/O Power Supply GEM80-400S Controller
If any fast I/O modules are fitted into the 400S controller which require a -15VDC
supply then a separate cubicle mounted supply must be fitted. The supply
should be capable of supplying 1 Amp at 15VDC +0.5V.
6.2.3. Fast I/O Subrack Power Supply Module
Table 6.2 details the specification of power supply modules. used in Fast I/O
Subracks

Consumption
350W per power
module when
supplying full rated
load.
Consumption
decreases
approximately
linearly with
decreasing load.
For ac operation,
input current at
full rated load
consists of pulses
of approximately
35A peak and
0.5ms duration
each half cycle.
For dc operation,
input current is
substantially
constant.
302W per power
module when
supplying full
rated load.
Consumption
decreases
approximately
linearly with
decreasing load.
Input current is
substantially
constant (not
pulsating).
