11 Fixed Voltage Settings For a 130 Ampere Charger

This is meant to be fun and not a challenge :) And the issue is not theoretical... Here we have a mean mean Meanwell RSP charger that has a max potential of 130 amperes. And the user cannot or d...

  • :5 digit LED panel and 2" color graph gauges. Digital ammeter
  • 200 ampere relay for reversed polarity protection
  • 10 second timer on output relay to allow capacitor inrush to proceed with battery loading
  • The delay allows for confirmation of voltage setting before engagement
  • Load is dispersed through 2 gauge Arctic battery cable and 800-amp battery clamps with shunts
  • Polarity protection includes piezo siren. Intermatic 6-hour timer
  • Genuine SJO power cable 14/3
  • Hospital grade Lexan 15 amp transparent plug
  • Mil-Spec 11 contact gold single deck switch
  • Pabst 120 mm double ball bearing 280 CFM 120vac fan for charger case
  • Extreme TVS and MOV suppression throughout circuitry AC/DC
  • Mr Wizard's inductive ammeter used :)
  • One watt metal wound mil-spec resistors are scheduled to be used in the voltage network
  • Since this is a charger with vast overkill inherent in the power cables I am not going to use remote sensing
  • Read the part again, where there will be a 10-second delay between startup and amperage engagement
  • Twin pilot LEDs announce powering the supply and engagement of the relay
  • Blue Seas 15-ampere AC breaker and Littlefuse 150 ampere self-reset DC breaker used on power leads
  • Unit is housed in a wheeled extension handled RIGID polyurethane tool box. Gauges are shielded with 1/4" LEXAN polycarbonate covered with 8 mil 3M adhesive
  • Lexan is removeable because it is secured with 30mm neodymium magnets and 18/8 stainless plates
  • Everything is soldered then buried in 3M corrosion liquid
  • Did I mention the 2nd Pabst 12 volt fan used for interior circulation.
