Sensor Specifications - Grundfos MAGNA3 32-60 F Notice D'installation Et De Fonctionnement

Leakage current
The mains filter will cause a leakage current to ground during
operation. The leakage current is less than 3.5 mA.
Consumption when the pump is stopped
4 to 10 W, depending on activity, such as reading the display, use
of Grundfos GO, interaction with modules.
4 W when the pump is stopped and there is no activity.
Input and output communication
External potential-free contact.
Contact load: 5 V, 10 mA.
Two digital inputs
Screened cable.
Loop resistance: Maximum 130 Ω.
4-20 mA, load: 150 Ω.
Analog input
0-10 VDC, load: Greater than 10 kΩ.
Internal potential-free changeover contact.
Maximum load: 250 V, 2 A, AC1.
Two relay outputs
Minimum load: 5 VDC, 20 mA.
Screened cable, depending on signal level.
Maximum load: 22 mA.
24 VDC supply
Capacitive load: Less than 470 μF.
Power factor
The terminal-connected versions have a built-in active power
factor correction, PFC, which gives a cos φ from 0.98 to 0.99.
The plug-connected versions have a built-in passive power factor
correction, PFC, with coil and resistors which ensures that the
current drawn from the grid is in phase with the voltage. The
current is approximately sinusoidal which gives a cos φ from 0.55
to 0.98.
