External current transformers
When fitted with external current transformers, the MP
204 unit can handle currents from 120 to 999 A.
Grundfos can supply approved current transformers
from stock (200/5A, 300/5A, 500/5A, 750/5A,
1000/5A).
Grundfos GO
The GO from Grundfos allows for wireless infrared
remote control of your MP 204 unit.
With the GO, you get access to a full range of options
such as factory setting adjustment, service and fault
finding.
Ready for bus communication
The MP 204 allows for monitoring and communication
via GENIbus, a Grundfos-designed bus for exchange
of pump data, alarms, status information, and
setpoints. This enables users to connect the MP 204
to, for instance, SCADA systems.
