Output voltage: +4 VDC, -4 VDC, +/- 4 VDC with voltage tracking
Output current: up to 80 mA
What are the tolerances for input voltages?
If 10VAC transformers cannot be found, can i substitute with 9VAC? Whould that be enough? 9VAC*1.4 = 12,6VDC
What about 12VAC? Because I see input capacitors are rated 16V, so 12VAC input would be too close to rated limit after rectification 12VAC*1.4 = 16.8VDC
