About the -48 VDC Products
The following items have been designed into the current -48 VDC products covered in this user manual:
Sentry firmware version 7.0 is provided with all -48 VDC black units, and with all -48 VDC beige/ivory units with
part numbers ending in “/Q”.
-48 VDC products with Sentry firmware version 7.0 more closely match the feature set of the Server Technology
AC Switched CDUs.
Generally, greater power distribution (greater than one output/outlet for each input/inlet) is provided.
Remote power management (Switched outputs).
Network and Serial RS-232 access.
Per Outlet Current Sensing.
NOTE:
The current sensing per outlet in the -48 VDC units is not the same as Per Outlet Power Sensing (POPS) in the AC product
firmware. The -48 VDC units only measure current (amps).
For Environmental Monitoring, each master unit supports two combination temperature/humidity probes.
Over-current protection is provided for each output:
o
GMT fuse for low-amp outputs up to 10A.
o
TPC fuses for high-amp output up to 125A.
o
Circuit breaker protection up to 100A available (with one model).
