FAQ: We need to take our LabScan XE instrument to Germany for some plant trial testing. Our machine is an UltraScan spectrophotometer 110v unit and, obviously, the power supply in Germany is 220v. The label on the back of the instrument says 110v-220V, which sounds a little ambiguous to me. Do we need a voltage transformer, or can we get away with only using a plug adapter (does not step-down current from 220v, only changes plug shape)? We don't want to ruin our instrument.
Answer:
All instruments currently sold by HunterLab come equipped with a universal power supply that auto-selects the correct voltage depending on the electrical system of the country. This 110V-240V rating means that the power supply will automatically switch from 110 to 240 volts without requiring a special voltage adapter or user intervention by changing a switch setting on the adapter. The only requirement is that the power cord connector that goes into the wall socket which must match what is used in the country. Even if you are travelling and don't have a connector adapter for the wall socket, you can easily purchase one locally.
FAQ: When I ordered my sensor, there was a choice of 110 volts and 220 volts. Is there a difference?
Answer:
Historically instruments had separate power supplies for 110 volts and 220 volts. Purchasing agents wanted to ensure that they purchase the correct power supply for the country that the instrument was being shipped to. The distinction in order numbers is just to ensure the comfort level of the purchasing agent.
Power supplies today are typically universal and can auto-adapt to a range of input voltage options from as low as 90 volts to as high as 240 volts. It's the same idea as when you travel to different countries with your laptop. You use the same power supply but just have to put a different wall plug adaptor on the power cord to use the computer in different countries.
HunterLab ships new sensor units with universal power supplies and the appropriate power cord connector for the country where the unit is going to.
FAQ: Do I need a UPS (Uninterruptable Power Supply)?
Answer:
As long as the power from the wall socket is steady, a UPS should not be necessary. Our systems can accommodate a power fluctuation of +/- 10% without difficulty.
