UC10.241, UC10.242
UC-Series
24V, 15A, CAPACITOR-BASED DC-UPS
7. READY AND BUFFERING RELAY CONTACT
The DC-UPSs are equipped with two independent relay contacts for remote monitoring and controlling of the unit.
Ready contact
Contact is closed when capacitor is completely charged, input voltage is sufficient and inhibit signal is not active.
Contact ratings max. 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A
resistive load
min. 1mA at 5Vdc min. permissible load
Isolation voltage 500Vac, signal port to power port
Buffering contact
Contact is closed when unit is buffering.
Contact ratings max. 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A
resistive load
min. 1mA at 5Vdc min. permissible load
Isolation voltage 500Vac, signal port to power port
8. INHIBIT INPUT
The inhibit input disables buffering. In normal mode, a static signal is required. In buffer
mode, a pulse with a minimum length of 250ms is required to stop buffering. The inhibit
is stored and can be reset by cycling the input voltage. See also section 23.7 for
application notes.
