LPUVA02AC
CONNECTIONS
The radiometer LPUVA02AC has
4…20 mA
output and requires
10…30 Vdc
external
power supply. It is to be connected to a power supply and an instrument with 4…20
mA input as shown in fig. 4.2. The load resistance of the instrument reading the signal
must be
≤ 500 Ω
.

LPUVA02AV
CONNECTIONS
The radiometer LPUVA02AV has
0…1 V
,
0…5 V
or
0…10 V
output (depending on the
ordered output) and requires external power supply:
10…30 Vdc
for 0…1 V and
0…5 V outputs,
15…30 Vdc
for 0…10 V output. It is to be connected to a power sup-
ply and an instrument with voltage input as shown in fig. 4.3. The load resistance of
the instrument reading the signal must be
≥
100 kΩ
.
