Celduc relays offers three types of solid-state relays for DC applications in PCB mounting. These are form factor similar to many electromechanical relays.
- The slim SLD single in line relay can switch 0-32Vdc 4A or 0-60Vdc 2.5A and is controlled with 18-32Vdc.
- The STD is a lower, double in line relay in 0-30Vdc 2.5A and 5A in two supply voltages 12-30Vac/dc or 12-30Vdc.
- The SPD relay is higher than the STD and can switch 0-30Vdc 5A. It is also available in two control voltages 12-30Vac/dc and 12-30Vdc.
A major advantage is the extremely long service life, as there are no mechanical moving parts in the relay. In addition, they are interchangeable with a large number of common electromechanical relays.
These solid state relays are widely used for frequent switching loads such as DC power supplies, batteries, heating elements, electromagnets and DC motors as well as in test equipment that perform endurance tests.
Celduc solid state relays are constructed with an input circuit, a switching circuit and an output circuit, which gives the relays high immunity. They can withstand high inrush currents and peak voltages.
