Description
Product Description
The Unison 901 ZDA 60 200 01 CU2 is a heavy-duty 200 Amp DC to AC Solid State Relay (SSR) designed for demanding industrial applications requiring reliable high-current switching. Built with Zero Cross Switching technology, this SSR switches the AC load at the zero-voltage crossing point, minimizing electrical noise, reducing inrush current, and improving the service life of heaters, transformers, and other connected equipment. It is an ideal solution for OEMs, panel builders, and machine manufacturers requiring dependable, maintenance-free switching in industrial automation systems.
The relay operates with a 4–32 VDC control input (4–16 mA) and switches 24–600 VAC loads up to 200 Amps. Its 2 mm copper (CU2) Direct Bonded Copper (DBC) base plate provides superior thermal conductivity and efficient heat transfer, making it suitable for high-current industrial applications. The SSR features 8 kV input-to-output isolation, 6 kV body insulation, integrated surge voltage protection, and a 10 kA short-circuit current rating, ensuring safe and reliable operation even in harsh electrical environments.
Unlike mechanical relays, the 901 ZDA 60 200 01 CU2 contains no moving contacts, resulting in silent operation, fast switching, resistance to vibration, and an exceptionally long operating life. The relay is widely used in industrial heating systems, large ovens, plastic extrusion machines, injection moulding machines, packaging equipment, textile machinery, and process automation panels where continuous heavy-duty operation is required.
For optimum performance, this SSR should always be installed with the recommended Unison heat sink. Depending on the application and cooling arrangement, larger heat sinks with forced-air cooling may be required for continuous operation at higher currents.

Frequently Asked Questions
1. What control signal is required for the 901 ZDA 60 200 01 CU2?
The relay requires a 4–32 VDC control input (4–16 mA), making it compatible with PLCs, PID controllers, and industrial automation systems.
2. Why is Zero Cross Switching preferred?
Zero Cross Switching energizes the load when the AC waveform crosses zero voltage, reducing electrical interference, minimizing surge current, and increasing the service life of heaters and other connected equipment.
3. Is a heat sink mandatory for this 200 Amp SSR?
Yes. A properly sized Unison heat sink is essential for safe and reliable operation. High-current applications may also require larger heat sinks and forced-air cooling depending on the continuous load.
