DC motor governor

220DP08BL Product introduction

DC speed regulating system is a high-precision electronic speed regulating device developed and produced by adopting the new international digital control speed regulating technology and special devices. The device adopts international standard technical specifications, and all technical indexes meet the requirements of similar products. It has the advantages of simple structure, small volume, light weight, etc. it can be used for constant torque stepless speed regulation of DC motor with power of dozens of W ~ 5kW in SZ series, ZYT series, Z2 and Z3. With multiple protection functions, it is safe, stable and reliable, fully compatible with similar products.

Mainly used in food machinery, fermentation equipment, packaging equipment, automotive equipment, pharmaceutical equipment and other automation industries.

1、 Features:

◆ pulse width modulation

Motor running noise, high efficiency, low maintenance, better improve the service life of DC motor.

◆ enable control function

One of the functions can be realized by a simple passive switch or transistor collector open circuit.

◆ double closed loop PI regulation (current, voltage)

◆ output current setting function

◆ torque compensation function

◆ soft start function

◆ over current and short circuit automatic protection function

◆ fault status indication

Power supply indication and various fault alarm indication can provide visual state of governor.

◆ standard analog signal interface (Note: it needs to be equipped with the company's special signal isolator - vid Series)
