Key Areas Where Solid-State Relays Are Used
Solid-state relays are deployed in a number of fields where their high performance is of utmost importance. For instance, they may operate within the following industries:
1. Industrial Automation
SCRs are involved in automated motor control, the operation of solenoids, heating control, lamps, etc. The possibility to switch on and off constantly makes them applicable in robotic devices and the assembly line.
2. HVAC
The high speed of ssrs makes them capable of controlling HVAC functioning.
3. Lighting
SSRs can be used for light dimming and switching on and off.
4. Medical Sector Solid-state relays are utilized in devices and systems that require silent operation, accurate controlling, as well as no need in maintenance, for instance, imaging devices and systems. Renewable Sources of Energy Solid-state relays work in solar and wind power systems controlling the whole distribution of electrical power or ensuring safe and efficient switching thus saving the environment.
REQUIREMENTS FOR UL CERTIFICATION FOR AMERICAN MARKET
1) Need for UL Certification Obtaining the Underwriter Laboratories (UL) certification for solid-state relays that are going to be manufactured and sold in the USA is of vital importance for the manufacturer. UL is an independent organization and a research center in safety science. UL certification guarantees that the product has undergone rigorous testing and meets marketability standards. While UL certification is not a legislative requirement for all electronic devices, the distributors and consumers tend to prefer UL certified products. This necessity makes it impossible to sell the product without UL certification, especially when speaking about the industry.
UL certification costs The amount of money required to get UL certification depends on different factors starting from the complexity of the product to its type and the number of tests required. When speaking about solid state relays, one can provide the estimates:
1) Initial evaluation and testing from $10,000 to $20,000
2) Annual inspections from $2,000 to $5,000
3) Document fees and charges from $2,000 to $5,000. So one basic conclusion one can make is that an average company will spend about $15-30 on UL certification in the first year and spend money every year for keeping it in force.
KANE ELECTRIC IS THE LEADING MANUFACTURER OF HIGH-QUALITY SOLID STATE RELAYS.
Kane Electric has been producing solid state relays for 14 years, thus gaining a reputation of a trustworthy company producing high-quality solid state relays. The products of this company provide outstanding durability, efficiency, and low maintenance.
To sum up, solid state relays are one of the most crucial devices used in modern automation and HVAC industries. The companies that want to operate in the USA should also get UL certification.
