Need 12v and 24 v latest battery charger parts

general text*Am constructing charging system on board construction equipment that people cannot remove. Need latest 12–15-amp limiter and auto-trickle after initial charging ckt. Ex; 110v input - rectified to DC - amp and volt limiter - shift to Off/trickle charge for maintenance. I have to hide/install these units in one 24v system and five 12v systems in order to ensure equipment is serviceable each day. Need parts list please. Kindly JB

Greetings,

A purpose-built battery charger would likely be your best option; rolling one’s own risks damage to equipment electrical systems, which would become expensive quickly. PB-300N-12 and PB-300P-24 seem like units that would be well-suited for hard mounting.
