Summary | 0000226: Upgrade UPS APC 350 to battery charger | ||||
Description | Transformer in APC CS 350 (step-up one, works in inverter mode) seems to have 3 coils: coil 1: xfmr double pin connecor goes to relay 68-12-2CE 12V 175 Ohm (BLK+WHT) - this is high voltage 230V AC output; coil 2: BLU wire goes to PHP 54N06T MOSFET (Q28) Drain, which Source goes to battery (-) , and low-voltage part BRN wire goes to PHP 54N06T MOSFET (Q14) Drain, which Source goes to battery (-) coil 3: BLK goes to battery (+) fuse RED goes to F1010E IR Power MOSFET drain and heatsink, which Source goes to battery (-) WHT goes to F1010E IR Power MOSFET drain and heatsink, which Source goes to battery (-) equal to GND | ||||
