Solid-state contactors proved to be good in industrial applications where high switching frequencies or high switching cycles are required. With their long service life and wearless switching they solve switching and control tasks in specific applications in an extremely economic manner. Application areas include:
Extrusion and injection moulding plants
Heating controls
Soldering lines
Hot-melt glueing robots
Oven controls
Three-phase motors
Lighting controls
Materials handling installations
Dispensing equipment
Packaging machines
Automats
Copying equipment
Pumps
Self-service automats
Traffic lights
... and many more
Advantages
Ready-to-use products and easy installation:
Snap on - Wire - Done
Long service life
Long service life
Noiseless switching
thanks to the use of semiconductors instead of electromechanical contacts
Excellent EMC properties
because of zero-voltage switching
Low space requirements
thanks to compact design and optionally up to 3 separately triggerable solid-state contactors within a single housing
Customer-specific solutions and special-purpose variants
e.g. with finely adjustable load circuit monitoring or with analog input for burst firing control for temperature controllers for cartridge-type heaters and other heating equiment
Suited for high switching frequencies
Low trigger current
only 5 mA
Rough environmental conditions
High I²t
therefore no extra solid-state fuse needed
Technology
DOLD semiconductior contactors and relays dead easily to handle
Ready-to-use products for your applications
With optimized parameters such as heat sink size, EMC, heat dissipation etc. To select the product which is best suited for your application it is enough to know the current flowing through your load.
Quick and easy installation
Simply snap these ready-to-use products on the top hat rail or screw them directly on the mounting plate.
Innovative technology
Switching of high load currents results in considerable heating of semiconductior contactors and relays. Inacceptable temperature rises may cause device failures after a time. To counteract this risk DOLD developed advanced technologies. Thanks to the DCB (Direct Copper Bonding) method it is possible to optimize heat dissipation in the power output element of the semiconductior contactors and relays and to ensure the operational reliability of your systems.
