NC Series

Solid state relay solutions grouped by load voltage for quick engineering selection.

10 Models Industrial Grade • SSR

SSR Engineering Summary

Control Voltage Groups: – 4-32VDC– 80-280VAC

Load Voltage Groups: – 24-280VAC

Current Range: 10A – 75A

NC Series Selection Check

Narrow the range by load voltage and current, then confirm control voltage, switching type, and document version.

10 models

Load condition Confirm AC / DC, single-phase / three-phase, load voltage, and maximum load current.

Control signal Match control voltage, control type, and zero-cross, random, or phase-control operation.

Thermal & accessories Review heatsink, fan, and safety cover needs by current, ambient temperature, and mounting style.

Document check Download the datasheet or send application details for KYOTTO model confirmation.
