Application manual is on our web site.5 Cleaning!Clean the product with a brush. Prevent liquid from getting intothe product.Do not soak the product into liquid.!Do not stick solvent to a name plate or a resin case.(If solvent sticks to a name plate or a resin case, it will causeto change the color of the case or to fade letters on name plateaway.)!After cleaning, dry them enough.6 Peak current?TUNS500F!The unit can generate the peak current under the following conditions.-t1[10[sec]-Ip[Rated peak current-Iave[Rated current-Duty=t1/ (t1+t2) x 100[%] [35%[A]Output currentt1t2Fig. 6.1 Peak currentIp : Peak currentIave : Average current!When aluminum baseplate temperature Tc is higher than 95C,Iave must be less than 95% of rated current.
