DAB ACTIVE DRIVER PLUS M/T 1 Pump Inverter

DAB ACTIVE DRIVER PLUS M/T 1 Pump Inverter

The Active Driver units were designed and manufactured to meet the needs of modern plumbing systems for constant pressure. Constant pressure regulation is useful in a variety of industries, including irrigation water supply, industry, hotels, housing construction, and thermal baths. The fundamental concept that guided our engineers in developing these units was to create a system that is simple, flexible, and reliable.

The Active Driver inverter is a pump control device with hydraulic system connections, a pressure sensor, a flow sensor, and an electronic frequency inverter. The Active Driver is used on the delivery of each electric pump, and it regulates the rotation speed of the pump to which it is connected, keeping the pressure constant despite variations in the required flow rate. Water flowing through the Active Driver Plus connections also helps to remove heat generated by the internal electric components.

Advantages

Constant pressure - Quiet operation - Economical - Reduced water consumption - Smaller footprint
(Expansion tanks not required) Less maintenance - Dry-running protection - Complete protection of the pump from faults.

Operation

When Active Driver detects a water request, it instructs the pump to start.  The pump's speed is (consistently) regulated to the lowest value that meets the user's request. This results in significant energy savings. When the first pump reaches its maximum rotation speed, the second and third pumps in this set are activated in cascade.

The pump pressure on Active Driver can be adjusted by the user using the + and - buttons (usually all of the pumps are set at the same pressure level).

The pumps stop automatically when there is:
Pump overload - dry-running - low voltage - Maximum pressure exceeded (adjustable) - Active Driver electronics overheating.

Displayed functions: 

Pump operational frequency (Hz) - Real-time pressure (bar) - Amperes absorbed by the pump - Alarms.
