DELTA ENERGY SYSTEMS [INDIA] PVT.LTD, DES India, is a 100% subsidiary of Delta Electronics, Thailand, part of the Delta Group. The company offers a wide range of Industrial Products comprises of AC Drives for major applications, Programmable Logic Controllers [PLC] , AC Servo System, Human Machine Interface[HMI], Temperature Controller, Optical Encoders, Communication modules, & Counter/Timer/Tachometers which has being developed by considering the industrial application requirements. Delta Industrial Automation Products are conforming to latest International standards with CE, UL & C-Tick markings.

Delta offers a wide range of AC Drives for most of the applications.

Delta make VFD-B is high performance powerful variable frequencies AC motor drive up to 100HP with overload endurance of 150% of rated current for 1 minute can be used for any general purpose application. It is a Sensorless vector drive with high torque performance [starting torque can be 150% at 1 HZ.] with auto torque and slip compensation feature. Close loop vector control is possible with optional PG card which enhances dynamic control performance. VFD-B has inbuilt Braking transistor up to 15 HP and with the optional Braking resistor or Braking unit, 125% braking torque is possible. VFD-B provides the option for setting of four sets of Accel/Decel time selection & independent accel/decl, S-curve setting. It has inbuilt Modbus communication feature via RS-485 port for communicating with other devices. There are 6 inbuilt programmable multi function input [NPN/ PNP type] for selection among 0-15 multi step operations, jog operation, speed up/down, counter, & PLC operation. VFD-B has one relay & three photocoupler O/P for indication of multi function output such as drive running, set frequency achieved, fault indication, drive is ready. It has two analog input [0-10V & 4-20mA DC] for speed reference and one analog output [0-10V DC ] for feedback of frequency and current and one digital frequency output signal. It is fully equipped with all the protection options such as self testing, over load protection, over-voltage/over-current stall prevention, reset after fault, speed search function, electronic thermal and ground fault. It has PID control, fan & pump control parameter which make this drive suitable for general purpose applications. VFD-B is suitable for both normal V/F control [fan, pump, and conveyor] and complex high torque vector applications [vertical stamping machine, compressor, punching machine, vertical lift, and elevator]. Delta make Drives are approved with CE, UL and C tick standards & Protection level IP20 and NEMA1.
