The WK and SK series DC motor stabilized power supplies adopt pulse width modulation technology and are designed and produced using advanced switching devices. They have the advantages of small size, noiseless operation, high efficiency, and advanced short-circuit technology
The protection function ensures frequent forward and reverse rotation of the motor, and the stability of the armature output voltage is high. The armature voltage can be continuously adjusted from zero to the rated value, which makes the motor speed regulation convenient. Due to its high operating frequency, this series of power supplies ensures that the motor can operate stably at low speeds (i.e. without crawling), making it an ideal replacement for thyristor speed control power supplies.
