Line protection
- Each controller includes a GFCI (Ground
Fault protection) and 16 A over current
protection (integrated to the GFCI).
- No fuse.

For information:
- standby consumption is 17 W.
- the max power available supplied via the
24V power supply (between pin 2 and 3 on
I/O connector):
CVI3 Essential, CVI3 Vision or CVI3
Function: 1 A (24V)
TWINCVI3: 2 A (24V).
Power consumption
The apparent power consumption is the only
needed information.
S = apparent power measured in Volt-Amps (VA)
S = U x I
rms rms
The apparent power peak is 6 kVA.
The duration of the peak is < 0.5 s.
CVI3 Essential / CVI3 Function / CVI3 Vision
The mean apparent power is always ≤ 1 kVA.
Single Phase 200-240 V
Single Phase 100-120 V
TWINCVI3
The mean apparent power is always ≤ 2 kVA.
Single Phase 200-240 V
Single Phase 100-120 V
External power consumption
The decision to install an external differential
circuit-breaker depends on the type of internal
electric network in the customer's plant.
This device detects any insulation defect
between one of the phases of the network and
the earth, immediately stops the tool by automatic
power cutoff and protects the operator from any
electric shock.

Should circuit-breakers be installed at the line
head, we recommend that you select equipment
with the following specifications:
- Single-phased 240V 16A - curve D
- Single-phased 110V 32A - curve D.

In a CVI3 controller, the power peak is 5kW.
To dimension an installation, the apparent power
