Power supply:
12 VAC (+10%, -15%), 50 / 60 Hz, 20 VA max. supplied by a class 2 circuit in c-pro 3 micro,
c-pro 3 micro+, c-pro 3 EXP micro and c-pro 3 EXP micro+; 24 VAC (+10%, -15%),
50 / 60 Hz, 35 VA max. or 20… 30 VDC, 12 W max. supplied by a class 2 circuit in c-pro 3
kilo, c-pro 3 kilo+, c-pro 3 EXP kilo and c-pro 3 EXP kilo+.
If the device is powered in direct current, it will be necessary to respect the polarity of the
power supply voltage.
Protect the power supply with a fuse rated 2 A-T 250 V.
Overvoltage category:

incorporated (with SuperCap battery); not available in
c-pro 3 micro BASIC (article code EPU2B and EPU2L)
not available.
Drift: ≤ to 30 s / month at 25 °C (77 °F).
Analog inputs:
According to the model:
• 6 inputs of which 3 configurable via configuration parameter for PTC / NTC /
Pt 1000 probes / 0-20 mA / 4-20 mA / 0-5 V ratiometric / 0-10 V transducers and 3
configurable via configuration parameter for PTC / NTC / Pt 1000 in c-pro 3 micro,
c-pro 3 kilo, c-pro 3 EXP micro and c-pro 3 EXP kilo
• 9 inputs of which 6 configurable via configuration parameter for PTC / NTC /
Pt 1000 probes / 0-20 mA / 4-20 mA / 0-5 V ratiometric / 0-10 V transducers and 3
configurable via configuration parameter for PTC / NTC / Pt 1000 in c-pro 3
micro+, c-pro 3 kilo+, c-pro 3 EXP micro+ and c-pro 3 EXP kilo+
