1. [AMPS] Constant Voltage (Sola) Transformer wanted (score: 1): Author: ve3zi@hotmail.com (Roger Parsons); Date: Tue, 13 Nov 2001 12:11:39 +0000; Hi I wonder if anyone can help me with a source for a CVT? I need minimum 2.5kVA, 208V input, 240V output, single phase. I really don't want to (can't!) pay Sola's new prices. This is for my remote s; /archives//html/Amps/2001-11/msg00223.html (7,866 bytes)
2. [AMPS] Constant Voltage (Sola) Transformer wanted (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Tue, 13 Nov 2001 09:39:41 -0500; If the application is for a capacitor input supply, good luck! You will need to restore the sine wave better than a sola transformer does, and have to use a greatly oversized regulator because of th; /archives//html/Amps/2001-11/msg00226.html (7,870 bytes)

The general consensus seems to be 'Don't use a Sola transformer if it's the last thing in the world!' I should perhaps explain the; /archives//html/Amps/2001-11/msg00233.html (10,315 bytes)

This looks like a case for either a regulated B+ supply which can compensate for changes in both ma; /archives//html/Amps/2001-11/msg00235.html (9,032 bytes)
