A700 SERIES Hi-Performance Low-noise Mini Vector Inverter is a new-type mini-AC inverter but packed with high performance features for induction motors available from 0.4-2.2kw which is the ideal solution to variable speed.
A700 is featured for SPWM design which provides low noise and high start torque. The inverter is independent and used in 50/60Hz (±5% fluctuation is allowable). The current overload rating is 150% for 60 seconds, sensorless vector control and V/F control make this inverter more brilliant for most general applications.
A700 is feature-packed, low cost and compact. The high-speed current limiting function minimizes over-current trips. Inrush current suppression plus grounding protection are built in for safe and trip free operation.
A700 is innovative design features; the digital operator includes a 3-digit LED status display. The multi-speed step function (7 pre-set speeds) and 4 acceleration/deceleration time make it ideal for food processing and its smooth speed variation can bring energy savings in fan and pump operation.
A700 also have multi-function I/O terminals, 0-10V, 4-20mA inputs and analog output, plus lip compensation, over torque detection and high speed search which all make this highly specified inverter a particular versatile inverter.
RS-485 Modbus serial communication port supports net work which is convenient for variety of host link allowing 32 nodes on a single net work.
A700 is proficient for conveyors, grinders, centrifuges, pumps, fans, and blowers used in material handling, packaging, food processing, and commercial laundry etc.
A700 is a perfect choice for high performance and low cost. Trust it for your success
