SUL8-SUM8 TYPES

celduc® relais offers the SUL8 and SUM8 models. These models are the "ready to use" versions of the SU8 models, with integrated heatsinks.

SUL9-SUM9 TYPES

celduc® relais offers the SUL9 and SUM9 models. These models are the "ready to use" versions of the SU8 models, with integrated heatsinks.

SOL Flatpac

These flatpac SSRs are mainly designed for applications where a PCB is used on the input, possibly on the output side. Wiring will be facilitated as this relay also allows input or output cables to go any direction.

SOP
Peak switching SSR for transformers starting :

Driving a saturable inductive load often generates high voltage peaks, which may damage the semiconductors used in SSRs (causing premature aging of relays) and break protection devices.

SOD
celduc® relais offers a variety of diagnostic relay solutions. These relays inform the user of the load's status (resistive load), the relay output, and the network.

SILD
celduc® relais offers a variety of diagnostic relay solutions. These relays inform the user of the load's status (resistive load), the relay output, and the network. The SILD power SSRs with diagnostics is offered in a compact package with an integrated heatsink.

SOI

Single-channel Power Solid State Relay with status output / Load Current

OPERATION: By applying or removing a voltage on the control input, the SOI relay switches or disconnects the current in the load. If the value of the load current is greater than the factory setting threshold, the current transformer included in the SOI will close the contact for signalling. It therefore indicates that a current is flowing in the load, then the user or the system interprets this status.

ADVANTAGES :

Reduction of quantity, cost and time of wiring

Elimination of the need to pass the power cables through a current transformer

Elimination of costly analogue inputs on the PLC

SLD-STD-SPD-SKLD-SCM-SOM

DC SSR with MOSFET Technology

DC MOSFET Solid State Relays are ideal for applications requiring transient overcurrent withstand (motors).

SKD-XKD-SCC

DC SSR - BIPOLAR Technology

DC Bipolar Solid State Relays are recommended for applications where a low control current is required.

SG4

celduc® relais offers single-channel angle controllers

These relays are designed to proportionally vary the switching point on a sinusoidal mains supply via an isolated analogue control signal, thereby varying the RMS voltage at the terminals of the load.

SO4

Phase angle controller - okpac® package

All the models from the okpac® range include TMS² technology for a longer life expectancy, integrated removable covers for IP20 protection, and screws with brake washers (captive washers and grooved terminals for better behaviour with shocks and vibrations).

SIL4-SIM4

Our range of Phase angle controllers is offered in a celpac® design with a built-in heatsink. The microcontroller managing these controllers can adapt the function to your application. This range is mainly designed for resistive loads.

SG5-SWG5

Celduc relais® offers a range of full-wave pulse controllers - single-phase power controllers

These controllers have an analogue input isolated from the mains to proportionally vary the operating duty cycle of a heating element (heating element batteries).

This control mode consists of switching the streams of full sine waves equally distributed along a fixed modulation period (TM) in accordance with the analogue input signal.

SO3 & SN8

celduc relais® offers a range of Burst control mode controllers.

This control mode is ideal for resistive loads that have a low thermal inertia, such as short wave infrared emitters (infrared heater bulbs).

It also makes it possible for the power to be finely modulated in accordance with the analogue control, while limiting disturbances.

This control mode consists of switching the streams of full sine waves equally distributed along a fixed modulation period (TM) in accordance with the analogue input signal. The μP constantly computes the number of full sine waves to be switched along the TM period.

SN8: Ultra miniature and flat solid state relay, designed for PCB applications, and when fitted with a suitable heatsink, can control heavy loads in an ultra-miniature, physically compact package.
