Always safe and reliable switching

High switching frequencies, long service life with minimum overall width from 22,5 mm

Wherever high switching frequencies and cycles are needed in industry, solid-state contactors and solid-state relays of the POWERSWITCH series are the first choice. In numerous applications in industrial and building technology, they perform switching and control tasks particularly economically. Their long service life due to wear-free switching is the reason for this. Dold also has an innovative answer to a problem encountered when switching high load currents, namely the strong heating of solid-state contactors and solid-state relays: The use of DCB (direct-copper-bonding) processes optimizes heat dissipation in the power stage of the devices and thus guarantees operational reliability of your systems.

DCB - Technologie (Direct-Copper-Bonding-Process)

The DCB technology (Direct-Copper-Bonding-Process) ensures very good heat transfer properties. Depending on the property of the heat sink, continuous currents of up to approx. 90 A are possible. If a large number of resistive loads have to be switched, the solid-state relays can be mounted on a collective heat sink.

More functionality, more possibilities solid-state relay / solid-state contactor

1-, 2- and 3-pole versions available

Solid-state relays of the POWERSWITCH series are ideally suited for mounting on existing cooling surfaces and allow fast and simple mounting with just two screws. With a narrow width from 22.5 mm, the solid-state relays are absolutely space-saving. Depending on the application, it is recommended to protect the solid-state relays against short circuits with special fuses. The solid-state relays offer a wide range of applications, e.g. in injection moulding machines in the plastics and rubber industries, in packaging machines, soldering systems and in the food industry.

Solid-state contactors of the POWERSWITCH series consist of a solid-state relay plus an optimized heat sink and are therefore ready for immediate use. Depending on the version, currents of up to 50 A are permitted. Like all solid-state switching devices, the solid-state contactors also impress with their narrow and space-saving design. Thanks to the pre-dimensioned heat sink, the devices can easily be snapped onto a DIN rail or mounted on carrier plates using fastening screws.

Solid-state contactors, also with load monitoring

Versatile options for individual configuration as well as DIN rail mounting

The solid-state contactors of the POWERSWITCH series are particularly suitable for installation in switch cabinets due to their simple snap-on mounting on the DIN rail and are available in 1-, 2- and 3-pole versions. Optionally up to 3 separate solid-state contactors in one device. The devices are characterized by a compact and space-saving design and allow fast mounting by snapping onto the DIN rail. Due to the ready-to-use design, the devices are immediately ready for use. With the device characteristics „zero point switching“ or „instantaneous switching“ you are equipped for all applications with AC loads.

Whether current monitoring, load control or analogue control, the solid-state contactors offer a wide range of applications, such as switching motors, heaters, valves or lighting. Special solid-state contactors can also monitor the load circuit. The solid-state contactors operate in a load voltage range of up to 600 V and, thanks to the wide control voltage range, can be operated with a PLC or simple temperature controllers. The devices cover a current range up to 90 A with only a few versions.

Reliable and noiseless switching

Application example PI 9260

In extrusion machines it is important to have constant process temperatures. This is the only way to ensure that the extruded parts have a constant quality. This is why solid-state relays are used to switch the heating elements. In contrast to mechanical contactors, these allow fast switching of the heating elements. Thus the temperature is regulated very precisely. Solid-state relays can withstand this operation over the entire service life of the machine because they are not subject to any wear.
