Industrial solid state relays simplify specifications in distribution
The KSV SSRs are aimed at applications such as PLC interface duties and process control in automation and processing equipment embracing high-low temperature chambers, plastics machinery, incubation machines, oiling machines, elevators, lighting, fountain controllers, the relays are aimed at designers, H&V panel builders, OEMs and system integrators.
The major benefit of the KSV series is its modular construction. The relays are supplied complete with a built in heat sink, DIN rail mounts and surface mount clip. Competing SSRs often have to order the relay, protection cover, thermal pad and heat sink all separately, and selection of the correct size of heatsink can be a challenge. A major benefit of the KSV series is that a single part number specifies and purchases a correctly rated and fully kitted out relay ready to install and use.
The KSV series provide fast, reliable switching, and with no moving contacts they are ideally suited to applications with high switching levels, rapid switching times and those requiring a very long electrical life. The SSRs have a fast operating time of 1ms, compared to 15ms for the mechanical equivalents. An added benefit of SSRs over electro-mechanical relays is silent switching. THhs is particularly important in large control rooms and in metal cabinets, where e-mech relays can be noisy, clicking on and off in applications where frequent switching is required. SSRs have no moving contacts and are therefore silent running, thus helping to reduce noise in the workplace.
The KSV series is available in four current ratings, 10, 20, 30 and 40A and are suitable for switching loads up to 280VAC or 530VAC for 240VAC and 480VAC relays respectively. The relays are available with DC control voltages of 4-32V or 90-280V AC dependent on the version selected. All types are available with zero cross turn on to minimise electrical interference, or random turn on for fast switching applications.
The 10, 20 and 30A relay versions measure 81 x 30 x 110mm, and the 40A version measures 120 x 50 x 110mm (HxWxD). KSV relays are supplied fitted with a built in LED that displays the status of the relay – ‘on’ when lit. Suitable for most industrial applications, the relays are able to operate in an ambient temperature range of -30 to 80 degrees C.
