Im re-powering an model-81 Powermatic bandsaw with a 3 HP Leeson DC motor (14 A max. draw) and a KBCC-255 motor drive (fused @ 15 A). I want to put some fans to cool the DC drive heatsink and LED pucks in the enclosure for work surface lighting. Fans 420 mA each, 1 light @ 170 mA.
I plan to wire the machine with a neutral.
- Would pulling 120 V (fused @ 1 A) from one leg to power a MeanWell SE-100 power be fine, similar to how a stove is wired?
- Running an isolation transformer 2x-120 primary 1x-120 secondary with neutral to prevent overcurrent on 12 V power supply, and unbalanced load on 20 A double pole breaker? Also ISK transformer on 12 V PSU transformer acceptable?
- Would using both 120 V legs (no neutral) be an acceptable circuit for the PSU-max input 264 Vwith neutral.
- Breadboard ISO transformer-rectifier-capacitor-regulator in place of the SE-100.
