Tips: Where frequency as low as 20 Hz or 10 Hz are used normally?
At 20 Hz and lower they are usually used for mining excavators (rotation). To rotate the higher structure of a mining excavator, it's used two or three motors (that's depends of excavator) runs by variable frequency drives (could be one drive or each motor have a drive and optical fiber communication to coordinate between the drives). The rotation of excavator are in steps and the steps are generally between 10 (15) Hz until 50 (60) Hz (generally there are 5 steps 10-20-30-40-50Hz- but in tests the final/realistic decision its taken).
The operator of excavator work between the second speed (20 Hz) and the penultimate speed (40 Hz) - he can stay in 20 Hz long period if the excavated earth is hard/rough. If not he can run in the 3 or 4 speed. All the speeds are used without problems.
Example for low than 10 Hz frequency: In special situations, the displacement of mining excavators can be done at 5 Hz (or around) but not for a long period. They need to do that in case of skating at the lower normal step/speed (if it's raining a lot the land can be difficult). The displacement could have also 5 speeds similar of rotation as values.

Recommendation of Suitable Frequency Converters
What frequency converter (60Hz to 50Hz, fixed voltage, 7.5kW power, 220V single phase) would you recommend for use with an electronic equipment Carbon-Sulfur Analyzer (not for solar application)?

Ive been using the 20kva freq. converter in my shop for 2 years now and it's proved very reliable.
I'm running 4hp uk spec (50hz@230v) woodworking machines in the usa.
My fluke meter shows exactly 50hz and the voltage is very stable hovering around 229.9-230.1v. Most of the time it's bang on the confugured 230v. The machines behave exactly as they did in the uk.
I also sampled the tech support as my unit was non functional when it arrived. Support was excellent and they quickly diagnosed a component that had come loose in transit. Reseating took seconds and the machine hasn't missed a beat since.
Can't fault the product or the company.

Is this a programmable frequency converter?
No, not regenerative. The output Voltage & Frequency are adjustable by rotary knobs, but you can program it by external PLC, which you have to state such requirement in order.

Is this a programmable frequency converter?
I am interested in this 20kVA single phase frequency converter, but I have some questions about it:
-Is it possible to make the power flow from one side to the other? (e.g. If I want to take some power from a 60Hz grid and start a motor, and later I want to inject energy to the grid from that motor)
-Are the values of input and output programmable? I would require an input of 50Hz and an output of 60Hz, but it would be better if we could program it and test it.
