Eco Block Modules

We have redesigned the product portfolio of 60 mm thyristor/diode modules with pressure contact technology. The Eco Block family addresses the demand for cost-efficient larger modules for rectifiers in drives and uninterruptable power-supplies (UPS), soft starters and bypass switches for UPS. Additionally, the modules are a perfect fit for large power supplies as well as windmills.

Due to its higher junction temperature, they are aiming at applications with air-cooled designs. The Eco Block modules feature all essential functions and make use of the pressure contact technology while stripping down costly extras. They provide best-in-class thyristor and diode blocking stability leading to high reliability and an outstanding lifetime. The pressure contact technology guarantees a short-on-fail feature, which in return prevents arcing.

In order to get the optimum performance and keep the production fast & clean they will be also available with Thermal Interface Material (TIM).

The Eco Block modules feature all essential functions while stripping down costly extras. The used pressure contact technology guarantees a short-on-fail behavior, which means that in case of failure the device is safely shorted. The short-on-fail behavior prevents from arcing in application failures which allows for simplified safety designs in terms of unit shielding and fusing effort.

Furthermore the used pressure contact technology offers a high overload capacity due to big thermal mass which absorbs high energy in short time range. The avoidance of soldered connections and bond wires eliminates the main aging effects in cycling loads. This results in a high reliability of the module regarding power cycling.

Combined, these features help to minimize failure rates and reduce system cost. With its proven reliability and functionality, the Eco Block offers the best value for money for a 60 mm pressure contact module in the market.

The 60 mm Eco Block family with pressure contact technology is available in high quantities. All modules are offered in the topologies Thyristor/Thyristor and Thyristor/Diode with a blocking voltage of 1600 V or 2200 V and in current ratings from 540 A to 630 A. In order to get the optimum performance and keep the production fast & clean they will be also available with pre-applied Thermal Interface Material (TIM). In 2021 we will introduce further products with 1800 V blocking capability.
