DC-UPS with Integrated Battery - 24V, 10 A
Relay Contacts and Inhibit
Input
The DC-UPS is equipped with relay contacts and signal inputs for remote
monitoring and controlling of the unit.
Relay Contacts
Signal Input
Contact State
Ready Contact is closed when battery is charged more than 85%, no wiring failure are recognized, input
voltage is sufficient, and inhibit signal is not active.
Buffering Contact is closed when unit is buffering.
Replace battery Contact is closed when the unit is powered from the input and the battery quality test (SOH test)
reports a negative result.
Attribute Description
Relay Contact ratings Max
Min
60V DC, 0.3 A, 30V DC, 1 A, 30V AC, 0.5 A resistive load
1 mA at 5V DC min.
Isolation voltage Max 500V AC, signal port to power port
Contact State
Ready The inhibit input disables buffering. In normal mode, a static signal is required. In buffer mode, a pulse
with a minimum length of 250 ms is required to stop buffering. The inhibit is stored and is reset by
cycling the input voltage.
Attribute Description
Signal voltage Max 35V DC
Signal current Max 6 mA, current limited
Inhibit threshold Min
Max
6V DC, buffering is disabled above this threshold level
10V DC
Isolation Nom 500V AC, signal port to power port
