I have a nexXTECH 75W mobile plug inverter and had lost the manual. I notice on the back under output it says 115 VAC, 60 Hz, 60 W cont and 75W for 5 minutes. Can you tell me what it means for 5 minutes?

If you are using a remote then you would set the machine in standard for controlling output and also to AC output, HF tig, contactor and control in remote position. I don't know if this helps or not but I pulled it from an owners manual.

1/16" (.062) - pre-flow .1 sec., hot start 20, amperage 70, Hz 100, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 100, background current 30, Hz 1.0

1/8" (.125) - pre-flow .1 sec., hot start 20, amperage 150, Hz 80, balance 20%, post-flow 6.0 sec.

For pulse settings - set pulse width 60%, peak current 150, background current 50, Hz 1.0

3/16"-1/4" - pre-flow .1 sec., hot start 20, amperage 185, Hz 60, balance 20%, post-flow 8.0 sec.
For pulse settings - set pulse width 60%, peak current 185, Background current 125, Hz 1.0

This generator is less than ideal to use as a home unit. see www.advanced-power-technologies.com and look at residential videos. Basically the voltage is governed by a capacitor on your unit, and ouput is directly propertional to speed. Also the engine is mechanically governered versus an electronic system. This is a common mistake using portables to power home equipment. You will damage your home digital equipment, do not use recommended

Radio Shack 230-0033 appears to be the same charger.

I have this charger (Nexxtech branded, model 2300033) and the specs all appear to line up. However, I don't have the manual.

What is the sound? Is the device working normally? Are there any lights or indicators? Do they indicate a fault or error?

A UPS runs on standard 110-120 VAC power. It converts the input power to DC and charges internal batteries, then back to AC. Connected devices actually run on the conditioned 115-120 VAC output. The batteries serve as a short term backup power source.

The electronics in the UPS can produce hum or high pitched tones. The sound should not be annoying. If it is louder than connected equipment (computers) it may indicate a problem. Hum is usually 60 Hz harmonics and difficult to eliminate. This harmonic may be transferred to audio equipment such as speakers or radios. A high pitched tone can be related to the rectifiers for the convertor/invertor. If the tone is loud, it means the rectifiers are drawing a lot of current. This is usually related to bad batteries.

Measure the voltage on the output receptacles. It should be 115-120 VAC. Disconnect everything on the output receptacles. Unplug the UPS from it's power source. If the output power dies within 1 minute, the batteries need to be replaced.

U.S and Canada: 20 VAC, 60 Hz Adapter: PS093B-20
Japan: 00 VAC, 50/60 Hz Adapter: PS093B-00
Europe: 230 VAC, 50 Hz Adapter: PS093B-230
UK: 240 VAC, 50 Hz Adapter: PS093B-240

Power adapter requirement straight from the user manual. I am sure you are aware that a simple plug adapter in a tourist shop does nothing to convert 120v US to 240v AUS. Note you unit does not like temperatures above 40C. And you can get that in Australia.

Bear in mind the timezone difference if you try Digitech support in the US.

Otherwise the power specs in the manual are here.
Power supply Input voltage/frequency 100 Vac, 50/60 Hz (Japan) 120 Vac, 60 Hz (North America) 230 Vac, 50 Hz (Europe) Output voltage/watt 12 V DC, 15 watt maximum

If this helps, please give a positive rating. Good luck to you!

Power supply details are as follows:
Input voltage/frequency 100 Vac, 50/60 Hz (Japan)
120 Vac, 60 Hz (North America)
230 Vac, 50 Hz (Europe)
Output voltage/watt 12 V DC, 15 watt maximum

The motor itself should have a sticker which describes the wiring for 115. It is a small change involving a single wire moving from one pole to another inside the motor starter cap (the bump on the motor itself).

1. You can buy a new power plug here.
2. You look at the power connector on your scanner and try to find a replacement with the following specifications:

Input voltage/frequency:

• 100 Vac, 50/60 Hz (Japan)
• 120 Vac, 60 Hz (North America)
• 230 Vac, 50 Hz (Europe)

Output voltage/watt:

• 12 V DC, 15 watt maximum

If you try to find an AC/DC converter yourself, make sure that the DC plug has the right +/- polarity and right size.
