Unfortunatly, this is a dual voltage supply (ie. 120/240, hence the switch).
The switch forms a voltage doubler with the caps and bridge rectified when fed with 120V AC - If you can find a dedicated 110V supply (or true multivoltage supply - ie. no switch to change between the two) you may have far better luck. Probably avoid PFC supplies as they often have 'brown-out' protection that may trip to protect the supply.
New evil decided - GNG offroad build on Craftworks DHR with 12S4P lipo. Aim - Light, balanced, powerful, able to climb a tree.
Project Vectrix restarted. Status - BMS + Charge control redesign (read faffing with batteries again)
