3.2 Technical outputs
The PSU has indication outputs:
EPS - absence of AC supply output
:
- OC type output that indicates AC power loss. Under normal status, with 230V AC supply, the output is
connected to ground (L level
– 0V). In case of power loss, the PSU will switch the output into high
impedance state hi-Z.
-
relay output indicating the absence of AC supply. In case of power loss, the PSU module will switch the relay
contacts.
CAUTION!
In Fig.5. the contact set in the potential-free status corresponds to a state with no AC
power (AC power failure).
PSU
– technical output indicating absence of DC voltage at the PSU
:
- OC type output indicating the PSU failure. In normal state (during correct operation) the output is connected
to ground (L level
– 0V). In case of absence of DC voltage at the output (e.g. short circuit), the output is
switched into high impedance state
– hi-Z.
- relay output. In case of a failure, the contacts of the relay change over.
CAUTION!
In the Fig.5. the set of contacts shows a potential-free status of the relay which
corresponds to a state with no DC power (PSU failure).
LoB
– technical output indicating battery voltage
:
- OC type output. Under normal status (U
BAT
> 11,5V) the output is connected to ground (L level
– 0V). In case
of decrease of battery voltage (U
BAT
< 11,5V) the output is switched into high impedance state
– hi-Z.
- relay output. In case of a battery voltage drop U
BAT
< 11,5V, the contacts of the relay change over.
CAUTION!
In the Fig.5. the set of contacts shows a potential-free status of the relay which
corresponds to a state with low battery level (U
BAT
<11,5V).
