AC DC Converters

LCM1500N-T is a high-precision industrial isolator based on high-frequency pulse width modulation (PWM) technology. The device integrates a high-precision zero-crossing isolation interface and provides a wide (375~525VAC) AC input voltage range, a wide (33~65Hz) AC input frequency range, and a range of 12~30V DC output voltage. It also supports programmable adjustment of the output voltage and frequency.

LCM1500N-T provides an effective solution for AC-to-DC applications in several industries, including industrial automation, instrumentation, industrial sensors, and aerospace. It also has applications in consumer lines such as lighting, educational robotics, and medical electronics. The device’s wide voltage and frequency ranges also make it suitable for use in high-temperature environments.

The working principle of LCM1500N-T is based on high-frequency pulse width modulation (PWM) technology. This technique is achieved by varying the duty cycle of a square wave AC signal from a pulse width modulator (PWM). This produces the desired variable DC output. The device contains a high-pass output filter for additional noise suppression.

LCM1500N-T can significantly reduce power consumption compared to linear converters. This is achieved by using synchronous rectification to enable high-frequency conduction of current between the AC and DC sections. This helps to reduce power consumption, resulting in improved efficiency and lower overall system costs.

The device is equipped with various features to increase system reliability and safety, including built-in EMI filters, over-voltage/over-current/overload/short-circuit protection, and regenerative back-up protection. These features ensure that critical components in the system are safeguarded from damage caused by misconnections or improper setup of the system. Additionally, the device complies with stringent safety regulations, including UL, VDE, and CE.

Overall, the LCM1500N-T isolator is a cost-effective solution for efficient AC-to-DC conversion in several industries. Its wide input voltage and frequency ranges, as well as advanced features such as EMI filters, enable it to be used in challenging applications. The device’s features make it suitable for use in commercial and industrial applications.
