Electrical data
* All MAGNA3 pumps are approved to run on both 50 and 60 Hz.
Sound pressure level
The sound pressure level of the pump is dependent on
the power consumption. Levels are determined in
accordance with ISO 3745 and ISO 11203, method Q2.
Pump type MAGNA3 (D)
Enclosure class Type 2
Insulation class F.
Supply voltage 1 x 115-230 V ± 10 %, 60 Hz*, PE.
Three digital inputs
External potential-free contact.
Contact load: 5 V, 10 mA.
Screened cable.
Loop resistance: Maximum 130 Ω.
Analog input
4-20 mA (load: 150 Ω).
0-10 VDC (load: > 10 kΩ).
Two relay outputs
Internal potential-free changeover contact.
Maximum load: 250 V, 2 A, AC1.
Minimum load: 5 VDC, 20 mA.
Screened cable, depending on signal level.
Bus input
Grundfos Communication Interface Modules (add-on CIM modules) for:
• GENIbus
• LonWorks+
• Modbus RTU
• BACnet MS/TP
• Ethernet.
Leakage current
I
leakage
< 3.5 mA.
The leakage currents are measured in accordance with EN 60335-1.
EMC
Standards used: EN 55014-1:2006 + A1:2009 + A2:2011, EN 55014-1:2017, EN 61000-6-2:2005,
EN 61000-3-3:2013, EN61000-3-2:2014.
Cos φ
Terminal-connected versions have 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.
Wire-to-wire versions have no PFC and therefore the power factor is from 0.50 to 0.99.
Consumption when the pump is stopped
4 to 10 W, depending on activity, i.e. reading the display, use of Grundfos GO, interaction with
modules, etc.
4 W, when the pump is stopped and there is no activity.
