Product Description
# Overview of ADTET AD300 variable frequency drives
AD300 series is a high performance general purpose AC drives integrated with the most advanced open & closed-loop vector control with PG. It can drive both normal AC asynchronous induction motors and PM synthronous motors with excellent control performance. Furthermore, it is designed to be robust with large capacity for heavy duty and complicated motor driving applications.
Thanks to ADTET strong R&D team and meticulous attention to QC and production, ADTET drives are equipped with many advantages, some of which are as follows:
#Power range
Triple phase 380V: 0.75kW~800kW (1HP~1100HP)
#Software Advantages
01. Unique current vector control algorithm with excellent software control platform;Realize decoupling of torque current and field excitation current.
02. RENESAS 32-bits high speed CPU specialized for motor control
03. Different control modes:
a. Sensor-less vector control(2 types: fuzzy/precise modes);
b. Closed-loop vector control with PG.
c. V/F control (3 types)
04. Speed detection restart(flying start)
05. Good linearity in torque control
* Adjustable from 0%~200%, avoiding runaway in torque linear increasing or declining
06. Dynamic torque current control makes sure the fast response to the load change.
07. Current limitation function for Acc.
*Its special current algorithm does not influence the starting torque, avoiding faults caused by the large starting current in some applications.
08. Extraordinary torque performance in low frequency
*SVC mode outputs 150% torque in 0.5Hz, meeting applications which require high torque at low frequency such as CNC spindle and crane
09. Strong overload capability (last 20 seconds for 180% current)
10. High precision speed control enables high precision synchronization control
# Structure Advantages
01. Independent air duct separates the electrical part from the heat radiation duct to reduce the damage rate.
02. European style compact structure design based on scientific heat radiation emulation; save the end user's panel space maximally
03. Full series drives use DC fans, avoiding the radiation failure caused by AC fans problems.
04. Drives housing: Good quality aluminum coated zinc plate and coating design provides not only reliable grounding and shielding but also anti-corrosive protection (11kW and above).
