18. Technical data
Supply voltage
1 x 230 V ± 10 %, 50/60 Hz, PE.
Motor protection
The pump requires no external motor protection.
Enclosure class
IPX4D (EN 60529).
Insulation class
F.
Relative air humidity
Maximum 95 %.
Ambient temperature
0 °C to +40 °C.
During transport: -40 °C to +70 °C.
Temperature class
TF110 (EN 60335-2-51).
Liquid temperature
Continuously: -10 °C to +110 °C.
Stainless-steel pumps in domestic hot-water systems:
In domestic hot-water systems, we recommend to keep the liquid
temperature below +65 °C to eliminate the risk of lime
precipitation.
System pressure
The maximum permissible system pressure is stated on the pump
nameplate:
PN 6: 6 bar / 0.6 MPa
PN 10: 10 bar / 1.0 MPa
PN 16: 16 bar / 1.6 MPa.
Inlet pressure
Recommended inlet pressures:
Single-head pumps:
•
Min. 0.10 bar / 0.01 MPa at +75 °C
•
Min. 0.35 bar / 0.035 MPa at +95 °C
•
Min. 0.65 bar / 0.065 MPa at +110 °C.
Twin-head pumps:
•
Min. 0.90 bar / 0.09 MPa at +75 °C
•
Min. 1.20 bar / 0.12 MPa at +95 °C
•
Min. 1.50 bar / 0.15 MPa at +110 °C.
EMC (electromagnetic compatibility)
EN 55014-1:2006, EN 55014-2:1998, EN 61800-3-3:2008 and
EN 61000-3-2:2006.
Sound pressure level
The sound pressure level of the pump is lower than 43 dB(A).
Leakage current
The pump mains filter will cause a discharge current to earth
during operation. I
< 3.5 mA.
leakage
Consumption when the pump is stopped
1 to 10 W, depending on activity, i.e. reading the display, use of
Grundfos GO Remote, interaction with modules, etc.
40
Input/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: 78 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.
cos φ
The MAGNA3 has a built-in active PFC (Power Factor Control)
which gives a cos φ from 0.98 to 0.99, i.e. very close to 1.
