Santerno Sinus variable speed drives

Santerno’s Sinus range of flux vector drives are suitable for all industry segments, and have power ratings from 0.4 to 2000 kW and supply voltages up to 690 VAC.

Each Sinus drive has a wide variety of I/O configurations in both digital and analog control to suit the simplest requirements or for more demanding applications, optional expansion cards are available. With the ability to integrate with a wide variety of fieldbus communication protocols including the popular DeviceNet, Profibus DP, ethernet and Modbus as well as having a minimal footprint size, retrofit installations with NHP and Santerno’s Sinus range is simple.

The Sinus Nano available from 0.4 to 2.2 kW to suit a single-phase 200-240 VAC supply contains easy-to-use front panel controls and a panel-mounted potentiometer for simple speed control. Able to operate in basic V/f operation or in sensorless flux vector mode for improved torque control, the Sinus Nano is suitable for all basic motor starting requirements.

The Sinus Micro available from 0.4 to 7.5 kW in both single-phase 200-240 VAC and three-phase 380-480 VAC supplies has the same features as the Sinus Nano in addition to additional firmware capability, making the drive suitable for use in HVAC installations with its ‘firemode’ operation. For those high inertia loads the Sinus Micro also has 200% starting torque capability and is ready to go with built-in dynamic braking with the ability to use additional brake resistors to achieve higher breaking torque.

The Sinus Penta is available from 4 to 1100 kW in three-phase 380-500 VAC supply and 75 kW to a 2 MW in three-phase 525-690 VAC supply. This model has an extensive range of control modes (including closed loop operation) and features to allow easy adaptation to all types of motor control applications.
