Hi all,

after approx 30 years of waiting our time has come to get hands on a Cyber 
180/860a.

These systems as other systems before are using 400Hz psus.

One approach would be to use a 50Hz/400Hz power converter. There are ones on 
the market creating almost pure sinus output with minimal harmonics.

Another approach would be to substitute the old psu by modern ones, possibly by 
DC-DC converters or switching powersupplies.

Does someone have experience in the substitution of psus in the multiple KW 
range or did this in the past?

Best

Andreas
