[Caevlist] 165vdc to 110vac inverter

[Allan Hesch]

This is the only estimate reply so far. I guess affordability won't be one
of its main features!

  Please advise exactly what the load is (a power supply, a motor, or what).

2)    Please provide the LOAD rating in watts - if it's a motor, we need to
know the locked rotor current in amps. If its electronics, we need to know
if the load is power factor corrected.

3)    Please confirm the input and output voltage if not already provided,
and if three phase state wye or delta configurations.

4)    Please advise us of any Military-Standards that apply and provide any
general application details – is this commercial, industrial, military?

5)    Please explain any pertinent environmental or electrical standards
that apply and advise us of any unusual issues we have not asked about.

6)    What is the quantity required?
