| Function Mode | Same core function (flashing→flashing, star-delta→star-delta) | Multi-function type can replace basic type |
7.2 선택 권장 사항
- Basic delay control: Prioritize ERV-XX series (ERV-12 for 0.1–12sec, ERV-03 for 0.1–3min)
- Complex sequential control: Choose ERV-XXD multi-function type (supports multiple delay modes)
- Motor starting applications: Star-delta starting must use ERV-YU/STER dedicated models for accurate switching timing
- Long-cycle control: Choose ERV-08/08중 (0.1sec–100h) for unattended scenarios
- Budget-sensitive projects: Chinese brand alternatives (친트, 맛있는) reduce cost by 30%–50%
