Information close
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.

Our extensive and diverse product assortment includes semiconductor relays, coming from our reliable suppliers and guaranteeing long-time and stable work of devices and whole systems.

Our offer includes products such as: 3-phase relays gn3 series, 3-phase relays with a heatsink for DIN rail, Crydom 3-phase AC relays. We also offer interface AC and DC relays for DIN rail and electromagnetic relays.

Solid State Relays

Solid State Relays (SSRs) are components used to control the current load by using a semiconductor controlled by a separated electronic circuit.

Electromechanical Relays - application

Relays of this type are used in many different industrial areas and control systems, and have many functions e.g. for galvanic isolation.

Other applications include switching high voltage overloads by using little power, or allowing the usage of receivers in the system, that are powered by sources with different voltages, despite the fact that there’s just one voltage level in this system.

Relay Cooling

The lifetime of Solid State Relay is virtually unlimited, provided that they are properly cooled. Therefore, special attention should be paid to the selection of the heat sink, use thermal grease and ensure adequate air circulation. A good solution is to mount the relay with a heat sink on the DIN rail, leaving around free space.
