The STP28X1.5MGR-Q is a product developed by a group of experienced engineers and designers. It is a mid-grade current-limiters designed to improve the efficiency of AC motors. It is especially suitable for high output frequency and high supply voltage applications. In addition, the STP28X1.5MGR-Q can help reduce motor noise and vibration noise.

The STP28X1.5MGR-Q is composed of a control circuit, including an analog current limiter and AC current measuring circuit. The analog current limiter can protect the motor from current overloads and over-voltage damage. This current limiter is able to handle more than 24 KVA input power. The AC current measuring circuit can detect the current in the motor and provides feedback to the control circuit to maintain the output current of the motor. Through the OCP chip, the maximum current that the control circuit will allow to flow into the motor is limited. This prevents the motor from overloading.

The STP28X1.5MGR-Q also features short-circuit protection and reverse polarity protection. When a short circuit occurs, the device will automatically disconnect the motor from the power source, thus avoiding damage to the motor or other components. The reverse polarity protection will ensure the safe operation of the motor when the power source is connected in reverse.

The working principle of the STP28X1.5MGR-Q is based on the physical principles of electrical current. The STP28X1.5MGR-Q is equipped with an analog current limiter that can detect the amount of current in the motor. When the current exceeds the upper limit of the threshold, the current limiter will automatically reduce the output power to limit the current flow. This is achieved by the control chip and the OCP chip which will increase the resistance of the output circuit, thus reducing the current flowing into the motor.

The STP28X1.5MGR-Q incorporates the latest technology and is designed for use in medium and high power applications. It is suitable for motors with input power of more than 24 KVA and with frequency range of up to 10 kHz. It is also suitable for use in applications with a supply voltage of up to 600 VDC. The STP28X1.5MGR-Q provides superior motor protection and improved efficiency. It is a reliable and cost-effective solution for all types of induction motor applications.
