Core Product Advantages and Features
70A single-phase rated current
Rated current 70A, output voltage range 48-460VAC, meeting common single-phase load specifications.
15-24VDC control voltage
The control input voltage corresponds to a standard DC control signal, making it more direct to connect to the PLC output.
22.5mm narrow design
With an external width of only 22.5mm, it is easy to install densely side by side inside the control panel.
Contactless semiconductor switching
Replacing mechanical contacts with semiconductor components results in arc-free and noiseless switching with a longer lifespan.
