Power supplies

The Eclipse HX-Median matrix has two Euro Cassette power supply units that can be
easily installed or removed as needed. One power supply unit can power an entire matrix.
The second unit provides a backup in case of failure or damage to the first unit.
In addition, the two supplies have separate IEC connectors to AC mains, and are designed
for completely automatic and transparent changeover between supplies in the event of a
power outage in one of the AC mains circuits.
An over-temperature sensor is connected to both an audible failure alarm and a warning
light, allowing the system operator to diagnose and correct any power anomalies while the
system remains operational.
Eclipse HX-Median matrices may be fitted with XP (part 740101Z) or Power-One (part
720379Z) power supply units, depending on the date of manufacture.

Table 3: Key to Figure 3: Eclipse HX-Median rear panel
The different types of power supply units must not be mixed in an HX-
Median matrix; if one of the pair of power supplies is replaced it must be
replaced with the same type of power supply unit. If this is not possible both
power supplies must be replaced with power supply units of the same type.
Power-One power supplies are identified by the part number on the front of
the unit. XP units do not have a part number on the front of the unit.
