Solid State Relays

Solid state relays (SSRs) are modern electronic components used in various industrial automation processes, providing essential switching technology to connect or disconnect electrical circuits. The CMD60110 is a solid state relay specifically designed for power capacitive loads. It has a robust construction, compact size and low control power consumption. This article will discuss the application field and working principle of the CMD60110.

Application Field

The CMD60110 solid state relay is widely used in numerous cases such as in motor control applications, cycle times of switching from 0 seconds to 20 seconds, test bench configuration, machines machines, HVAC Control, lighting control, door control systems, appliances control, uninterrupted power supplies (UPSs) and other applications that require reliable power switching and control. Its high frequency of up to 50kHz and high voltage of 480VAC makes it ideal for these specific cases. It can also handle very short switching cycles due to its high switching frequency rate. In addition, the CMD60110 is a perfect choice for cases that demand a reduced on-state conduction heat and additional surge protection. This is due to its patent pending design of specific MOSFETs that enable high surge protection capability of up to 300V and reduce conduction losses. This quality makes the CMD60110 a great choice for applications that need high-load power switching with shorter cycle times.

Working Principle

The CMD60110 is a zero-voltage switching solid state relay. It operates by sending a low voltage DC control signal to the relay, which is converted into an AC output voltage. This type of solid state relay uses a semiconductor switch consisting of power MOSFETs or IGBTs to open and close the path connecting the two terminals. It is based on the principle of zero-crossing detection, wherein the voltage drop from the AC power lines to the conduction power MOSFET is switched on or off at a point when the voltage becomes zero. CMD60110 has an operating temperature range of -40°C to 85°C and a dielectric strength of AC 2500V for 1 minute. Its maximum power is 500 Watts and the current range is 10A to 600A. It also has a high control signal voltage range (3V DC to 40V DC) and an improved long-term performance. These features make it a suitable component for varied industrial applications. Overall, the CMD60110 is a robust and reliable solid state relay that provides essential switching capability for various applications. Its wide range of specifications and highly efficient characteristics make it a great choice for power switching in short switching cycles.
