Pushing water uphill
Cascading Toshiba variable speed drives are providing precision pressure control in the latest mains water booster pumps being built by Allan Aqua-Systems.
Measuring just 72 x 130 x 100mm, the Tosvert VF-nC1 not only sets new standards for size, the design saves further space because the units can be installed side-by-side as cabling is from the top and bottom of the units.
Users can choose between wall and DIN rail mounting.
The process of installation is simplified by the provision of screw clamp terminals for the mains power, and the VF-nC1 has been carefully designed so that it can be swapped out with an electromechanical motor starter to upgrade a fixed speed system.
Commissioning and operation are as simple as installation.
Setting up the five basic operating parameters via the six buttons plus potentiometer on the front panel will cover the requirements of 90% or more of all applications.
The VF-nC1 is equally suitable for more complex programming, with setup being menu driven via the display above the buttons.
A software wizard function simplifies programming still further.
All parameters are lockable to secure the drive against unauthorised tampering and resetting.
The advanced motor control software at the heart of the VF-nC1 coupled with flux vector operation ensures cutting edge performance, with 150% torque at start up and frequency control over the full 0-200Hz range.
The carrier frequency is adjustable up to 16kHz so that audible noise can be tuned out, a significant feature for applications in nonindustrial environments where noise is highly undesirable.
All models have proportional-integral control as standard for optimised performance in pump and fan applications, plus a serial communications port for network interconnection as standard.
Some of the features that make the VF-nC1stand out include multiple preset speeds, DC injection for maximum control at startup, built-in high performance Class B RFI filter, choice of two or three wire control, slip and IR compensation and overload/trip out logging.
The VF-nC1 is available in 0.1-2.2kW ratings, 100 or 200V and in single- or three-phase formats.
OEMs addressing export markets will note that it meets all the relevant major standards in all geographic regions, including UL, CSA, CE and C-tick.
