The IC697PWR722 24 VDC Power Supply Module is a module that can be attached to the left side of a rack, or can be mounted as a stand alone unit. It provides +5 volt, +12 volt and –12 volt regulated DC power outputs as well as a ttl compatible logic shutdown signal, named TTL. This power supply module must be connected to a Power Supply Adapter (PSA) module (IC697PWR720) which plugs into the power supply slot in an IC697CHS* rack. The PSA module connects the power supply outputs to the IC697CHS* rack backplane and monitors the TTL signal, as well as the +5V, in order to provide logic level sequencing signals to the backplane. The physical connection
from the power supply to the PSA is through a cable that is connected to the power supply at the factory
The 24 VDC power supply module can be used either in a single rack application, or can also be used to provide power to a second rack if the total load is within the supply rating. Interconnection to the second rack is made through an available prewired cable
(IC697CBL700). Protection is provided for overcurrent and overvoltage fault conditions.
Features:
• Operation from +21 VDC to +32 VDC
• Three regulated DC output voltages, 90W total
+5 VDC output at 16.5 amps
+12 VDC output at 1.5 amps
–12 VDC output at 1.0 amp
• Mounts external to rack
• Electronic short circuit overcurrent protection provided on all outputs
• Input power fail and system reset signals
