Variable speed drives

NHP carries stock of the Santerno range of variable speed drives, which includes the Sinus Nano, Micro and Penta drives.

The Sinus Nano covers 0.4 to 2.2 kW to suit a single-phase 200-240 VAC supply and features easy-to-use front panel controls. It can operate in basic V/f operation or in sensorless flux vector mode for improved torque control and is suitable for all basic motor speed control requirements.

The Sinus Micro is available from 0.4 to 7.5 kW in both single-phase 200-240 VAC and three-phase 380-480 VAC versions and includes ‘firemode’ operation suitable for HVAC installations. Sinus Micro also has a 200% starting torque capability and built-in dynamic braking with the option for additional brake resistors when required.

The Sinus Penta is the fully featured flagship drive of the ‘Sinus’ range. It is available from 4 to 1100 kW in three-phase 380-500 VAC supply and 75 kW to 2 MW in three-phase 525-690 VAC supply. The Penta boasts an extensive range of control modes with many special features for adaptation to all types of motor speed control applications.
