Question about Liebert UPStation GXT2700RT-208 (GXT2700RT-208B) UPS System

50Hz to 60Hz conversion

Is it possible to set up the unit so that the input is 240V 50Hz and the output is 240V 60Hz? I need to power 60Hz US made equipment in a European country and can use a transformer to step down the voltage but still need frequency conversion.

    I have bought an upscaling DVD player and a high end home theatre system (Pioneer Elite 530 watts and Definitive technology subwoofer and speakers 300 watts) for use in UK. I am going to use a 2000 watt step down converter with built in stabilizer and delay switch. Please advise if I need to consider solving the 50 / 60 Hz issue and is the converter capable of handling the equipment mentioned above. Thanks.

Hi, Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards. P.S. The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.

    Hi again,

    of course the power output of the UPS must match if not be higher than the load/device requirement.

I recently purchased a Pioneer SC-07 in North America(110v/60Hz) and need to convert it to use in Australia (240/50Hz) Am I able to purchase power supply to make this happen?

You need to locate a power converter. This is basically a trqansformer that will convert the 240V system into a 110V system. These are generally available anywhere where travel supplies are sold. You can also contact Pioneer and see if they have a conversion kit which would require the replacement or alteration of the internal transformer on the unit.

What power supply is needed for hp scanjet 2400

It is depends on your scanner power adapter and where u purchase the scanner from. Here if your scanner is from US then the adapter power input should be 100-120V 60Hz AC, if your scanner is from Euro, UK or Australia, the it should be 200-240V 50Hz AC, while if your scanner is from others place that not listed above then it should be 100-240V 50-60Hz AC.
But the best way is look at your adapter itself, u'll notice the power input and output from the adapter sticker.

If you lost your adapter then be sure to purchase 1 that can output a 12 VDC, 340mA, 4.22W adapter to the scanner.

US portastudio 2488: Can it play when connected with a transformer

The 2488mkII manual specifies that the unit can operate with either 120VAC, 60Hz (USA/Canada), 230VAC, 50Hz (U.K./Europe), 240VAC, 50Hz (Australia) so you should be fine with a transformer which can accomodate 230VAC, 50Hz).

I have actually conversed with people who have been using the 2488 in France without any power problems.

Samsung hcm5525w rear projection tv

Extensive analysis revealed this unit to be for 120V 60Hz regions. If you use it in a region where the mains supply is 220/240V 50Hz then it won't work. In addition, the PSU will overheat, with possible damage to other modules.
One possible solution is a 120V 60Hz inverter, else Samsung may be able to provide the correct PSU for 220/240V.
