The CUS200M18 is an AC/DC converter designed to drive electronic motors and other applications. It is specifically designed to provide high-power output with low voltage, as well as solid state protection against short-circuits and other faults. It is ideal for use in a variety of applications, such as motor control and robotics, and can also be used in industrial automation systems.

The CUS200M18 is a digital, open-frame AC/DC converter that includes a step-down power stage for the conversion of AC voltage into a separated DC voltage. The converter can be used for higher output voltage applications. It has full compatibility with standard frequency drives and motors and uses an internal zero-cross switching circuit to reduce input voltage interference. The converter also provides power de-rating feature, allowing it to be used in motor control applications with continuous loading.

The device is equipped with a built-in overcurrent protection circuit, temperature control, voltage regulation, and PFC (power factor correction). It has a wide operating range of -40°C to 105°C and can be operated over a wide switching frequency range of 20kHz. The unit is designed to withstand up to 25kV ESD pulses. It has built-in dual-channel current limit protection, undervoltage lockout protection, and overload protection that will protect against high-voltage faults.

In terms of its working principles, the converter functions similar to a motor control power supply. The starting current can be limited on the AC side and the full load current is regulated on the DC side. The AC side of the converter is connected to the AC supply and the DC side is connected to the load. The starting current limitation is provided by the AC input voltage, while the minimum current is set by the internal of the converter. The minimum load current set by the internal can be adjusted, giving the user flexibility in terms of the output performance. The converter’s voltage regulation capabilities mean that the output voltage is very accurately regulated even under variable load conditions.

On the AC side, the CUS200M18 features a full-frequency rectifier that converts the AC voltage into a direct current. This DC voltage is then rectified and regulated on the DC side of the converter. The input voltage is monitored and the load current is regulated by means of a current loop, which provides accuracy in the output voltage. The internal current loop reduces noise and can also provide dynamic regulation of the output power. Finally, the converter also features a soft-start function that reduces inrush current.

The CUS200M18 is an excellent choice for motor control and industrial automation applications, providing excellent voltage, current, and temperature regulation. It is fully compatible with standard frequency drives and motors, as well as a variety of other electrical devices. Its built-in protective features provide a safe and reliable operating environment, and its wide operating range make it suitable for a variety of applications.
