When it comes to solid state relays (SSRs), the company carries universal SSRs, analog inputs, logic inputs, wattcor, drives, and SSR drivers and accessories.

The universal types are labeled as ‘zero crossovers,’ which means they’re reliable when switching electrical loads.

These SSRs have 10 to 40 and 3 to 32 VDC trigger voltages and 400 Vac. 25A, 250Vac load ratings.

Currently, the company carries 12 products under the SSR category.

These products include 20A/36V one-channel Mosfet relay modules in 3.3V to 10V logic, 3 to 32V DC input SSRs, and 5V one-channel 15A/36VDC time relays.

Unfortunately, there is no discussion on the individual specifications of these SSRs. So, when you need to order them, it’s better to inquire directly from the company.

Riecktron is a dealer of international and world-renowned brands like Arduino, Helium, Carbide 3D, Lumenati, and Raspberry Pi.

These brands supply the local market with different products such as audio chips, development tools, sensors, and power accessories.

The good thing about the company’s online platform is it has an indicator of its current inventory.

Meaning, you can check, in real-time, if a specific product is available. If it’s not available, they also indicate the number of days it takes before they can be ordered. 

In terms of SSRs, they carry 3 to 32V DC input 40A ones with stock code COM-13015. These SSRs could switch up to 40A current load at zero cross-trigger control and 3 to 32V DC input.

Each of these relays comes with four different screw terminals, which can be used with fork or ring connectors. Aside from that, it also comes with covers that slide over the SSR surface to protect its terminals.

The efforts these companies put into their research, development, and networking programs are visible in how their target markets respond to their products and services.

With this, there’s no reason why you shouldn’t consider South African manufacturers as your SSR partner.
