MPDCD3

MPDCD3 is a solid state relay (SSR) specifically designed to provide a low cost, low power, reliable and efficient means of controlling AC loads. It is the second generation of SSRs from Omron, the Japanese leader in industrial automation solutions. The MPDCD3 is based on a zero-voltage switching (ZVS) design which enables it to switch very rapidly with no additional power dissipation. It is well suited for controlling loads with inrush currents, making it ideal for high power applications such as motor drives, conveyors, compressors and pumps.

The working principle of the MPDCD3 is based on Omron\'s patented ZVS switching technology. This technology makes use of a fast voltage switching circuit to provide near-instantaneous power to an AC load. When the control switch is triggered, a brief voltage pulse is sent to the MPDCD3 which in turn supplies short-circuit current to the AC load. At the same time, the ZVS circuit switches off the output voltage, resulting in a fast switching of the load. The technology ensures that the transfer of the output voltage from the triggered to the non-triggered state occurs within microseconds. This eliminates the need for larger and more expensive relays.

The MPDCD3 is rated for operation up to 40 Celsius and can be used in temperatures up to 70 Celsius. It is available in three different current ratings: 25A, 50A and 100A. The MPDCD3 also includes a built-in constant current limiter and over-current limiter for extra protection. The rated operational life of the MPDCD3 is also excellent, with an expected life of up to 100 million switch cycles.

The MPDCD3 is ideal for applications requiring high speed and low power switching of AC loads. Some of the common applications include motor drive, pump and compressor control, and conveyors. The MPDCD3 is well suited for industrial applications where a reliable and efficient control of AC loads is required without sacrificing safety and performance. The low cost and long expected life make it an ideal choice for budget-conscious applications.

In conclusion, MPDCD3 solid state relay is an advanced and reliable device ideal for applications that require a high power and low cost. Thanks to its ZVS switching technology, it is possible to switch power from the triggered to the non-triggered state within microseconds. Moreover, it is available in different current ratings and its rated life is up to 100 million switch cycles. The MPDCD3 is suitable for applications including motor drive, pump and compressor control, and conveyors.
