Delta’s VFD-EL-W series is the new generation compact vector control drive. Simple, delicate and durable design inherits Delta’s superior drive technology. Various essential functions are built-in as standard, including: Multi-step Operation; Torque Compensation; PID Control; Multi-Pump Control; Water Supply at Constant Pressure; Leakage Detection function and so on. It also with complete built-in protection mechanism, such as: Over-current; Over-voltage; Low-voltage; Over-heat; Over-load; Over-torque and Phase Loss Protection. VFD-EL-W not only saves the extra cost but also increase the market competitiveness with the best technics. Applications: edge banding machine, logistic conveyor, material handling and constant pressure pump.
