The OKY3496-9 is a PWM (pulse-width modulation) controller manufactured by OKYSTAR. This module is capable of controlling currents up to 10 Amps, and can operate between 4 to 60 Volts. The OKY3496-9 is built with a Hall Effect sensor, which provides an accurate feedback loop to the controller, increasing operational efficiency. It can control both DC and AC motors, and can be used to control the speed of both motor types. The module also has protection features including Under-Voltage Lockout (UVLO), Over-Voltage Protection (OVP), Thermal shutdown (TSD), and Short Circuit Protection (SCP). It has two sets of frequency control pins and a logic-level enable/disable pin. This module is ideal for applications that require a high current with precise control with an economical price tag.
