Compliance

All Series 45 Electric controls have met and passed the Danfoss PLUS+1

®

compliance standard testing,

and as such, this Series 45 control is PLUS+1

®

compliant. PLUS+1

®

compliance blocks are available on the

Danfoss website, within the PLUS+1 Guide section.
Electric Proportional Control Principle

The Electric Proportional Control consists of a proportional solenoid integrated into a Remote Pressure
Compensated control. This control allows the pump to be operated at any pressure limit between the
Load Sense and Pressure Compensation settings by varying the current sent to the solenoid.
