Dear  ,

Here are the latest News from celduc® relais over the past month:

New range of Solid State Relays with built-in TVS protection

-Protecting AC SSRs against voltage transient phenomena-

In fact, any voltage that exceeds the maximum permissible voltage, could potentially damage the SSR. If overvoltage conditions are likely to occur (e.g., lightning, voltage spikes from turning off inductive loads like motors and transformers, …), the outputs of the SSRs require an overvoltage suppression device.

There are different kinds of overvoltage suppression devices to protect Solid State Relays outputs from voltage extremes such as overvoltage transients :
-Protection by RC Network (known as “Snubber”)

-Protection by TVS (Transient Voltage Suppressor)

-Protection by Varistors (MOV (Metal Oxide Varistor) / VDR (Voltage Dependent Resistor)

celduc® relais has just launched a new range of Solid State Relays with built-in TVS protection and suitable for standard industrial loads (SO9 and SUL9 series).

In our new blog article we explain you the various types of protection devices available in celduc’s range of Solid State Relays (SSRs) and provide suggested recommendations on their selection.

Thermal Pads or Thermal Paste : How making the right choice ?

The proper sizing of the heatsink is not the only consideration when creating an SSR assembly. Another critical consideration is the proper mounting of the Solid State Relay to the heatsink itself, which can greatly effect the efficiency of the “thermal system” and therefore the operation and reliability of the assembly.

We herewith explain the use of thermal interface materials (TIM) that are placed between the SSR and the HeatSink to improve thermal performance.

Challenges and opportunities in the renewable energy market

Consumption of renewable energy has grown worldwide. Renewable energies are a great opportunity for Solid State Relays. 

celduc® relais’ expertise is focused on developing and offering solutions for the renewable energy market, especially photovoltaic cell manufacturing. celduc® relais also offers solution to monitor and control the efficiency of renewable energy plants. Here are some of the most common applications for Solar Energy, Wind Energy and Biomass Energy.
