Type: PSA Power Supply Adapter Module, ⚠️ It does not come with a power conversion circuit and must be connected to an external independent power supply (such as IC697PWR721/PWR722). The external power supply is connected to the rack backplane through cables and is not a self powered power module.
key parameters
Occupation: 1 slot, must install the leftmost power slot 0 of the rack
Backplane output capability (determined by external power supply, maximum load capacity of PSA)
+5 VDC：18 A
+12 VDC：2 A
−12 VDC：1 A
Self power consumption: Take 50 mA from the backplane+5V
Signal: Monitor external power TTL OK signal; Output ACFAIL and SYSRESET power timing signals to the backplane; Equipped with 5V remote detection
Cable: Connected to an external power source through a dedicated cable; IC697CBL700 cable can be used to power the second expansion rack
Compatible racks: IC697CHS750 (5 slots), IC697CHS790 (9-slot rear installation), IC697CHS791 (9-slot front installation) and other 90-70 racks
Working temperature: 0-60 ℃; Humidity 5-95% without condensation
Weight: Approximately 0.57 kg

Features
Transfer external DC power supply (GE original power supply or third-party external power supply) to supply 90-70 rack backplane
Monitor external+5V power supply and TTL level Power OK signal
Generate backplane system signals: ACFAIL, SYSRESET, to achieve power failure alarm and system reset timing control
Support dual rack power supply expansion configuration
No built-in AC-DC conversion, external power supply is required and cannot be directly connected to mains power
