I can try to make a better estimate somehow tonight, no problem. At this point I would say somewhere from 5 to 10 watts is powering the bulbs.
But it is variable to a fairly fine degree. There can be more loss and less load power (usable effective power) or the other way around. I can adjust
it so it hardly changes at all, I think I have some big core losses at that frequency too though, it's just a laminated steel motor core. At first I thought it was
a bit strange that the fluro light up so well and still increased current draw at that frequency but then when I seen the waveform was made more resonant
looking it made sense, a different load. I would imagine I should be able to reduce the PW to regulate the power as well if I want. One thing I think I have learned
that must be respected with power transformers that I want to "idle" is that they simply must produce the required flux and not waste it,
ie. if the primaries don't have enough turns for the core cross sectional area the transformer won't stop the primary current enough with no load
on the secondary and the transformer won't idle with low input power.
If I can get something free from my or a setup with a battery I won't complain.
I think I damaged my scope or I'm trying to use it wrong. When I set it to AC and sync mode INT - on the 1/100 setting with a HV probe
I think it's 1/100, funny things happen, the circuit uses more power and funny sounds also happen.
So I used a 10 kOhm resistor to the
probe from the Active terminal and the probe ground to the grounded common neutral then the resistor smoked up. So I stopped trying
to scope it directly at that point as I was getting a signal anyway at HF. I seem to be able to scope to output from transformer to the motor
it looks kinda funny. Maybe I can scope the 120 volt tap and see something there to measure. Even though the scope is only cheap it is useful
I would not be surprised if i already damaged it though.
I'm up for suggestions about the scope, maybe I'm trying to use it wrong. Or did.
Cheers
