The inverter (DRIVE-TECH) is a device for the control and protection of pumping systems based on the variation
of the supply frequency of the pump. It can be applied to both new and existing installations guaranteeing:
•
Energy and cost savings
•
Easy installation and lower costs of the system
•
extending the life of the system
•
increased reliability
The inverter (DRIVE-TECH), connected to any pump on the market, it manages the operation to maintain
constant a specific physical quantity (pressure, differential pressure, flow, temperature, etc. ..) at change the
conditions of use. In this way the pump or pump system, operates only as and when needed thereby avoiding
unnecessary energy waste and prolonging battery life.
At the same time the inverter (DRIVE-TECH) is capable of:
•
Protect the motor against overload and dry running
•
implement the departure and the 'sweet stop (soft start and soft stop) to increase the life of the system
and reduce the absorption peaks
•
provide an indication of current consumption and supply voltage
•
record the hours of operation and function, and functions of this, the errors and fault reported by the
system.
•
control other two pumps at constant speed (Direct On Line)
•
connect to other inverter (DRIVE-TECH) to realize the combinated operation.
Special chokes (optional) allow the inverter (DRIVE-TECH) to break down the dangerous overvoltages that
occur in long cable runs and then make the inverter (DRIVE-TECH) optimal control of pumps.
GENERAL TECHNICAL DATA
- Power supply voltage: 230 Vac ±15% single-phase; 380-460Vac±15% three-phase;
- Frequency 50-60±2% hz
- Protection level: IP55.
- Maximum working temperature: 40°C.
- Working position: the inverter (DRIVE-TECH) can be installed directly on the fan cover.
For installation and operation of the pumps in combo mode (1 master and 1 slave), you must use one sensor
for each inverter (DRIVE-TECH) present; Please remember to take the offset of the connected sensors on each
machine. Each slave can potentially replace the inverter (DRIVE-TECH) master in case of failure, so all
parameters must be set independently on each inverter (DRIVE-TECH) group in master mode. To operate the
group is sufficient to press the green button (START) of only inverter (DRIVE-TECH) master; Inverter (DRIVE-
TECH) each slave can be arrested independently in case of need by acting on the corresponding red button,
compatibly with the water demand of the system and the possibility of being replaced by a further device. If
