CU 200 SQFlex control unit
CU 200 is a combined status, control and communication
unit designed for the SQFlex system. Moreover, CU 200
enables the connection of a level switch placed in a water
reservoir or tank.
CIU 903 SQFlex control unit for remote
monitoring
CIU 903 is a combined monitoring, control and
communication unit designed to work directly with a SQFlex
pump. When combined with a CIM 280 GRM module, it
enables remote monitoring through Grundfos Go. Moreover,
CIU 903 can be connected to a start/stop switch, a level
switch or a pulsating water meter.
It also works with Grundfos GO.
IO 50 SQFlex switch box
The IO 50 is a switch box designed for switching the system
power supply on and off.
IO 101 SQFlex switch box
The IO 101 is a switch box designed for switching the
system power supply on and off.
The IO 101 is used in solar-powered SQFlex systems with a
backup generator.
IO 102 SQFlex breaker box
The IO 102 is a breaker box designed for switching the
system power supply on and off.
The IO 102 is used in wind-powered or wind- and solar-
powered SQFlex systems.
The IO 102 slows down or stops the wind turbine.
Charge controller
The charge controller is used when a battery backup system
is installed with an SQFlex pumping system.
Solar modules
The Grundfos solar modules are developed specifically for
the SQFlex system. The solar modules are equipped with
plugs and sockets enabling easy connection in parallel.
The number of the required solar modules depends on the
following:
• quantity of water
• head
• location of installation.
For further information on solar modules, contact Grundfos.
Generator
In case the primary power supply is temporarily insufficient,
the SQFlex system can be powered by a diesel- or gasoline
generator.
Batteries
The SQFlex system can be powered by batteries with
a 30-300 VDC voltage supply of and a maximum current of
8.4 A. DC power supply operation is limited to the highest
possible power depending on the voltage. For example, 48
VDC provides a limiting maximum power of 403 W.
