Placement [DC Input] + - + [OUTPUT] 24V 1A=24W BD7682FJ-LB © 2016 ROHM Co.,Ltd. [Three Phase AC Input] P. 3 4. Evaluation data DC300V DC600V DC900V This data is using DCIN Tested one hour after switch on. ( Thermister hot situation ) Using ACIN input low voltage situation, Efficiency little bit low down. Please see next page. © 2016 ROHM Co.,Ltd. P. 4 5. Efficiency Data From each Input Terminal © 2016 ROHM Co.,Ltd. P. 5 6. Efficiency Data From each Input Terminal DC from DCIN DC from ACIN AC from ACIN DC300V/AC220V DCIN Output Current (A) ACIN This board has two input terminal. DCIN and ACIN. Efficiency depend on input terminal. Because of input impedance not same. © 2016 ROHM Co.,Ltd. P. 6 7. Parts List © 2016 ROHM Co.,Ltd. P. 7 8.
