Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

DACPOL is an experienced supplier of products in the power block category. Our customers can rely on the quality of the products and services we provide, whether they purchase power blocks for rectifiers and AC switches, power blocks for welding machines, or high-voltage diode stacks.

Reliable power blocks offered by DACPOL

We are ready to deliver bulk quantities of the product you are looking for, and on our website you will easily find all other necessary items from the semiconductor category.

We care about the safety of our customers, which is why we offer only products from trusted suppliers and manufacturers. We consult with specialized engineers to provide you with information on the maintenance and use of purchased products.

DACPOL’s offer in the Electronics Components, Power Supply, and Connectors group is much broader and includes far more than just various types of electrical and industrial products in the power blocks category.

Custom orders at DACPOL

For custom orders, DACPOL can supply modular blocks made from radiators other than those listed on the website, with devices installed from any manufacturer.

High-voltage diode and thyristor stacks. Parameters of stacks other than catalog specifications require individual parameter agreements.

Applications of power blocks

Power blocks are used for building machines and devices for industry. Their construction is adapted to operate under harsh industrial conditions. Power blocks consist of diodes or thyristors mounted on radiators appropriately selected for their current-carrying capacity. They are primarily intended for building rectifiers and thyristor switches in more complex devices.

Power blocks can also be used for other purposes

They come as single-, double-, or triple-element units with air or water-cooled radiators. Semiconductor power devices used in blocks come in screw, disc, and electrically insulated module housings. The current-carrying capacity of the blocks ranges from 30A to 5,000A, and the voltage class of the devices ranges from 100V to 8,000V.

In our offer, you will also find relays and contactors.
