New Original DELTA VFD015S21D Single Phase Input AC Variable Frequency Inverter<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The DELTA VFD015S21D belongs to the VFD-S series economical general-purpose AC variable frequency inverter. It accepts single-phase 200~240 V AC input and generates adjustable three-phase AC output for 1.5 kW (2 HP) induction motors. Adopting V\/F scalar control mode and SVPWM modulation technology, this drive features built-in operation keypad, integrated RS-485 Modbus communication interface and internal PID function. With compact mechanical layout, comprehensive protective mechanisms and simple parameter configuration, it is widely applied on small conveyors, packaging machinery, fans, water pumps and light-duty automation equipment. The supplied unit is brand-new original genuine DELTA product.<\/div>\n<\/div>\n
