SSR Derating Curve
- The heatsink of the curves is dedicated for the SRH2/SRH3.
- Install SR2 / SR3 Series on the metal plate (min. 130 × 120 mm).
- Be aware that the ambient temperature and the derating curve are different by the rated input voltage when using the product.
When installing multiple SSRs, be sure to keep space between SSRs for heat radiation. When installing SSRs horizontally (input part and output part on the same height), be sure to supply less than 50 % of the rated load current.- SSR derating curves obtained approval from the UL certification authority.
