Electronic device for the electric pumps control based on inverter
technology.

Specifications

Controls start-up and stop of the electric pump and modulates the motor revs. depending on the withdrawal of water from the plant.

Materials

• Constant pressure due to motor pump speed regulation
• Energy saving due to less pump absorption
• Gradual pump start and stop reduces hammering and avoids
breakaway starting current
• Protection against dry running in event of water shortage during intake
• Automatic reset in event of dry running, with autonomous error
condition recovery
• Efficient leakage monitoring to protect pump in event of repeated
restarts
• Digital pressure display
• Motor over current control
• Operation/error status signalling via LEDs and on-screen alerts
• Operation in master/slave confi guration into twin booster sets
• Double set point with remote control option
• Remote start and stop of electric pump
• Rotation direction inversion via software (it does not require wiring
alterations)
• Extractable terminals to facilitate wiring

ACCESSORIES:
Connection cable for connection in twin booster sets 4x0,5mm2
100 cm (SR-CBL4X05-100)
