Hi, i need help on this issue: I bought a laser printer that operates at 1080W, but my 110V-240V step up/down transformer has a maximum capacity of 1000W, and now i cant even turn on my battery charger which uses 110V-240V. can anyone explain what went wrong?
It's not quite clear how your battery charger and step up/down transformer are associated or if you tried to use the step up/down transformer to power the laser. I'm guessing you tried and it didn't work and now your step up/down transformer doesn't work either. Since you've exceeded the power output of the step up/down transformer by using the laser, one of several things may have happened: 1. there is a safety fuse that has been blown in the step up/down transformer 2. there is a built-in circuit breaker that has been tripped in the step up/down transformer 3. you've damaged the circuitry/wiring in the step up/down transformer permanently 4. if the battery charger was plugged in at the same time (theorizing it is a separate device) it may have been damaged by the low power available by the power draw of the laser that the step up/down transformer was trying to supply You should always verify the power requirements of equipment to that of the supply before using them together and remember to calculate for total power of everything that is plugged into the supply that is being used at the same time. It is recommended that laser printers should not be plugged into power strips or surge protectors unless they are specifically designed for that heavy of a power load as most are not. If you haven't already, try removing them all from power for a few minutes or a couple of hours and then try plugging them in one at a time to a standard wall outlet to see how they respond. I would have to see them all to evaluate specifically what was wrong. Best of luck.
