Stepdown Transformer Frequency Ask Question Page Stepdown Transformers convert the voltage but not frequency Australia = 50hz frequency America = 60hz frequency Frequency difference may effect some appliances but only those that are frequency sensitive. USA Microwaves, Hair Trimmers , Dog clippers Analogue clocks and Flouroscent lights are frequency sensitive and may not work - (see bottom of page for solutions). Devices with Motors? Devices with Motors will have a slightly difference performance with the frequency difference in Australia. Note: USA Devices with a DC motor machine won't be effected greatly by the frequency hertz difference. However if your device has an AC Motor it will be effected. The motor may run a fraction slower and thus warmer using a stepdown transformer, However in most cases your USa device wil still run correctly without much noticeable performance difference. KITCHENAID mixers frequency difference & tortech stepdowns : Kitchenaid mixers often come with either the 325w or 575 or 700w motor models. The frequency will make the mixer motor run slightly slower but this does not effect the performance of your mixer. Our stepdowns have been designed to ensure your mixers motor is not damaged over time: From our experience and in house testing kitchenaid mixers run perfectly even with the frequency difference (50hz in Australia) and this does not degrade or damage a USA kitchenaid mixer overtime. Due to the frequency shift from 60 to 50hz this effects the heating in the motor due to the larger field in the magnetic circuit of the motor, however this has been compensated in our stepdowns by setting the input voltage at 110v not 120v to guarantee the longevity of the insulation structure of the motor by reducing the induction in the magnetic circuit of the motor. We offer a 1 year warranty on all our transformer range. The output power will be reduced only at maximum setting to a degree. However it is our experience that tortech stepdown transformers still function satisfactory and this is our experience from over a number of years of selling our transformers for kitchenaid mixers.
Amplier and sound Questions - why a higher stepdown may be required for quality Amplifier is a device that amplifies audio signals. Audio signals consist of treble (high frequency sound) and base (low frequency sound) response. The base response is affected by the current delivery capability of the AC Supply. If the supply is soft the AC supply will Sag and hence this will mean the DC supply voltage will sag. Hence this will compromise the sound quality of the base response. The solution is to by a larger transformer to stiffen up the AC supply to stop the voltage from sagging. Always add 20% extra power usage ontop of the input watts. Eg Amplifier rated at 200watts input may need 240watts for optimal.
Fast Drill Chargers like Dewalt and Makita : Although these drill chargers say they only need 100w this may not be so. If they are a "fast charger" they infact draw extra power due to the current being very high during the initial stages of charging a flat battery. During this time the current will exceed the nominal current. Hence You will blow the fuse on the normal rated stepdown 0 Solution is to use the 250/300w stepdown A common question "we notice your transformers say 110v and our enquiment is rated at 120v will it still work?" Answer - Yes All our Transformers support USA equipment 110v-120v Our stepdowns run at 110v because of the numerous safety advantages for your USA equipment: 1) The supply voltage in Australia is 240v +/-6% So it can legally go to 255v at 50Hz. The transformer is a linear device so the output voltage responds to the change in the input voltage. This a means the output voltage (110v) will go to 116.8v if the transformer is loaded . If it lightly loaded this voltage will go even higher to 124V If we used 120v as the transformer output voltage, the appliance could be overvoltaged to 134v This is may not good be for the longevity of the appliance. 2) If the appliance is a motor, the matter is it subject to the affect of frequency change from 60Hz(USA frequency) to 50Hz(Australian frequency). To alleviate the frequency affect it helpful to reduce the voltage from 120v to 110v, to reduce the induction level in the motor. The magnetics of the motor will then not run as hot as it would if it was run at 120v Isolated vs Auto differences > Click here to read Further information on The Frequency difference: United states is 60hz frequency where as Australia 50hz frequency. Our stepdowns don't change the Frequency so check if your device is frequency sensitive or has a timer or analogue clock please ask us before you purchase a stepdown. If it has a frequency switch on your appliance then flick it to 50hz. Clocks may run slower or out of time. TVs LCD PLASMA or LED ? Frequency concerns ? Hair Clippers? Frequency hertz change can effect Clippers - please ask us, you may need to come into out office for a special unit. Hair and Dog Clippers from the USA are effected by the frequency hertz difference (australia is 50hz - USA 60-hz) clippers may tend to be overloaded running on 50Hz Here, so you may need a custom unit made for this. < No products > |
