DC Solid State Relays Online

Are you in need of solid-state relays in your device? Get the best-in-market Crydom solid-state relay online from Fastron Electronics. A DC or an SSR relay is used as an electronic switch to control AC or DC voltage. They offer better service life when compared to electromechanical relays due to the absence of any physically moving parts. Solid-state relays have semiconductors instead of moving mechanical parts and using an optocoupler are able to isolate the low voltage circuit from the high voltage. At Fastron Electronics, our range of DC relays, and solid-state relays include Crydom - Sensata exhaustive range of SSRs and 12 V solid state relays.

FAQ's


1. What is a DC solid state relay and how does it work?
A DC solid state relay is an electronic switch that controls DC voltage using semiconductors instead of mechanical parts. It offers longer life and better reliability by isolating low- and high-voltage circuits through an optocoupler.
2. Where can I buy reliable DC solid state relays in Australia?
You can buy high-quality DC solid state relays in Australia from Fastron Electronics, which stocks a wide range of Crydom SSRs and offers technical advice.
3. What are the advantages of using a solid-state relay over a mechanical relay?
A solid-state relay lasts longer and performs better than mechanical relays because it has no moving parts, making it more reliable and silent in operation.
4. Do you offer 12V solid-state relays for DC switching applications?
Yes, you can find 12V solid state relays for DC switching at Fastron Electronics. These are ideal for various low-voltage applications.
5. How do I choose the right SSR relay for my project?
You can get help choosing the right SSR relay by reaching out to Fastron Electronics, which offers free technical advice for selecting the right product.
6. What current and voltage ratings are available for DC SSR relays?
Fastron Electronics offers DC SSR relays with various current and voltage ratings, including models such as 3A, 7A, 10A, and 40A, suitable for loads of up to 500VDC.
7. Can I use a solid state relay for switching low-voltage DC loads?
Yes, you can use a solid-state relay for switching low-voltage DC loads. Fastron Electronics stocks several suitable options for such applications.
8. Are your DC solid state relays suitable for industrial applications?
Yes, the DC solid state relays available at Fastron Electronics are ideal for industrial use and come from trusted brands like Crydom.
9. What is the lifespan of a solid state relay compared to traditional relays?
A solid state relay generally has a much longer lifespan than traditional electromechanical relays, thanks to its non-contact design.
10. Do your SSR relays include heat sinks or require external cooling?
Fastron Electronics stocks SSR relays along with pre-drilled panels, DIN rail mount heat sinks, and custom cooling solutions when required.
11. How do I properly install a 12V solid state relay?
To install a 12V solid state relay, you can follow the specifications provided or get in touch with Fastron Electronics for technical guidance.
12. What is the difference between AC and DC solid state relays?
AC solid state relays are designed to switch AC loads, while DC solid state relays are used for DC loads. The internal circuitry differs based on the voltage type.
13. Do your SSR relays come with safety certifications?
Yes, Fastron Electronics supplies certified SSR relays from trusted global brands, ensuring quality and safety for all applications.
14. Can I purchase solid state relays in bulk quantities?
Yes, you can purchase solid state relays in bulk from Fastron Electronics and even request customised pricing for large projects or BOM orders.
