Celduc: New SMQR Quad Series Solid State Relay
March 27, 2024
Celduc’s Solid State Relays are designed for industrial applications where fast and long electrical life in switching is required. celduc relais has recently launched a new range of Quad AC Output Solid State Relay.
With this new SMQR Series you will get four independently controlled AC output Solid State Relays in an industry standard package. With the models SMQR and SCQ, celduc relais offers a choice between push-in spring terminals or Faston terminals.
These products are zero-cross switching and are especially designed for AC-1 resistive loads.
What are the benefits of zero-cross switching?
Zero-cross switching is also called zero voltage control. With this type of control, power switching takes place only at the beginning of the alternation after the control has been applied. In the case of resistive loads, it is preferable to use zero-cross relays which in this way limit the disturbances on the network and increase the lifetime of the load and the relay.
How large is this SSR ?
Thanks to its compact dimensions of 100 (L) x 48,1 (H) x 45 mm (D), SCQR Series is a good fit for tight setups.
Integrating 4 single-phase relays in a « sightpac » style housing, the SMQR product family is the best choice to reduce the size of your control panel (compact 45mm version). It can be said that the SMQR package conserves space while providing high-power switching.
What are the main product features of the SMQR Series?
- 4 x 25A power element
- 10-30VDC control voltage
- 24-600VAC switching voltage
- Zero voltage turn-on version
- Optimized for resisitve loads applications
- Quick connect style terminals
- Green control status LED visualization for each input
- Overvoltage protection by TVS diodes on gates
