Features

Wide Applications
This inverter is applicable to both asynchronous motor and synchronousmotor; therefore, it helps users to decrease the inventory since there is no problem of incompatibility for different types of motors.

Excellent Performance
SVC: 1:200; starting torque: 0.25Hz/ 150%; multiple braking modes; quick magnetic flow brake without braking resisto

Strong Adaptability
Goodrive 300 has a compact structure, independent air duct, high power density and low requirements on installation environment. The independent air duct enhances the protection effect, so that Goodrive 300 can be used in various hostile working environments. Besides, the two installation methods, i.e. board mounting and flange mounting meets the demand of different users.

Multiple Functions
Two sets of motor parameters, V/F separate control, virtual terminal function, rotational speed tracking, relay delay output; Two sets of motor parameters allow users to use one inverter for different motors and help users to save cost; V/F separate control meets the demand of variable-frequency power source and achieves the flexible V/F curves.

High Reliability
Goodrive 300 obtains CE certification and has multiple protection functions and high reliability.
1. Goodrive 300 adopts thermal simulation technique; therefore, it has good heat dissipation effect and maintains high reliability.
2. Goodrive 300 is built-in C3 EMI filter to eliminate interference from outside and enhance system compatibility.
3. Goodrive 300 series passes various tests in terms of high temperature, low temperature, low pressure and vibration, which ensures high reliability before delivery.
4. Goodrive 300 series has got TUV-SUD certification, and has TUV mark and CE certification mark. It reaches the highest technical standards in Europe.
5. High-quality hardware: wide input voltage range, support DC input, DC bus, built-in braking unit (below 30KW), external high-performance LED keyboard, a great quantity of I/O terminals, C3 EMI filter, etc.
Optional Accessories
