• The SHT three-pole solid-state relays have been designed in a compact housing for printed circuits. This relay is designed for PCB applications. Added to a heatsink, it provides control of medium power in three-phase networks.

• Designed in a single, low-profile package, this range of three-phase AC solid-state relays is specifically designed for medium-power control in three-phase applications.

DATASHEETS

• The SMB models are two leg three pole solid state relays. They have been designed to control three-phase loads with a delta connection, and if well balanced, with a star connection without neutral. Two of the three phases are switched, and the third is directly connected.

• The sightpac® series consists of three solid-state outputs controlled by one input. It has the same function as any standard solid-state relay. When the input signal is applied, each output conducts load current for its respective phase in the network.

• Motor control has always been something difficult to tackle, as a motor is first of all an inductive type of load with high starting currents (which doesn’t help reduce the size and costs of protection devices like fuses) and overvoltages generated at turn-off. 

This is why Solid State solutions are more and more popular to control motor loads. Another big advantage of using power electronics is that numerous control modes can easily be performed thanks to very fast response time, and the computing power of micro-processors. Celduc Relais, specializing in Solid State Relays, manufactures in France with a high level of quality a complete range of Solid State Contactors for motors, as well as soft starters and motor reversers.
