card and dry contact extended card.
Provides extended monitoring ports:
five relay output ports and five input
ports.
Detects mains and bypass backfeed
and provides protection.
Reinforces the cabinet so that the
cabinet can resist intensity 9
earthquakes.
Collects ambient temperature and
humidity, and can be applied to
batteries.
Detects current leakage and
generates alarms. When equipped
with a remote trip switch, the
detector protects devices and
prevents fire outbreak. Detects
battery grounding failures and
generates alarms when the ground
leakage current exceeds the specified
value.
Transmits bus synchronization signals
in a dual-bus system.
Connects UPSs in parallel.
