New feature on our e-shop : the Stock Alert Our e-shop aims to easily allow you to check the stocks and delivery times of our references. Nevertheless, it can be challenging to remember our delivery times for all the references that interest you, and that are out of stock. celduc® relais has then decided to […]
“dv/dt” and “di/dt” values : what impact does the level of these values have on a Solid State Relay ? Excessive levels of di/dt is one of the main reasons for thyristor failure. When this occurs, the stresses applied to the semiconductor devices can significantly exceed the rated values and damage the power element. In […]
Basics for protection against transient voltages celduc® relais has just launched a new range of Solid State Relays with built-in TVS protection and suitable for standard industrial loads. We take this occasion to remind you how to protect AC SSRs against voltage transient phenomena. There are different kinds of overvoltage suppression devices to protect Solid […]
Are high inrush currents on startup causing damages in the transformer primary circuit ? Switching ON the primary of an AC transformer can often generate high inrush currents. Applying electric power to the primary of a transformer can lead to more or less big troubles, especially if this operation is intended to be very frequent. […]
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 if the proper mounting of the Solid State Relay to the heatsink itself, which can greatly effect the efficiency of the “thermal system” and […]
