[QUOTE="Tururu, post: 980276, member: 227656"] Si el ventilador es de corriente continua (12 voltios) no hay problema. Si es de 230Voltios corriente alterna, [B]depende de tipo de motor[/B]. [U]Cuidado, puede que funcione, pero se calienta mas de lo normal y gira mas despacio.[/U] Todos funcionan bien con [B]sinusoide pura[/B], pero en los sai/UPS baratos es sinusoide cuadrada y/o modificada y no les gusta a muchos motores. Los compresores de los frigorificos al estar en carga tienen un pico de arranque que puede tripicar el consumo durante unos segundos ([B]400x3=1200)[/B], aparte de ser un [B]consumo inductivo[/B], que ya jode. El generador 3.5kVA tose cuando se inicia el congelador. Un generador inverter, de 1Kw no tiene problemas con los frigorificos, el generador normal (potencia real a medio gas 50%), como dices, suele toser.:-doh ------------ If the fan is DC (12 volts) no problem. If it is 230 volt AC, [B]depending on engine type[/B]. [U]Care, might work, but warms more than usual and rotates more slowly.[/U] All work well with pure sine wave, but the sai / Cheap UPS is square and/or modified sine wave and do not like many engines. The refrigeration compressors being in peak load have a boot that can tripicar consumption for a few seconds ([B]400x3 = 1200[/B]), apart from being an [B]inductive consumption[/B], which already sucks. The 3.5kVA generator coughs when the freezer starts.:-doh An inverter generator, 1 kW have no problems with fridges, normal generator (real medium gas 50% power), as you say, usually they cough.
