I recently installed a Progressive EMS-HW30C electrical management system in my motorhome. I installed it before the breaker box and all other electrical equipment to protect everything when plugging in at campgrounds.
When I was winterizing I took a good look at the various items hidden under the rear bed and found that I have a Progressive Dynamics (different company than the EMS) PD-9260 power converter with a Charge Wizard attached.
PD9200 Series RV Power Converters
I shortened the verbiage from their website, but here is a list of everything the PD-9200 series converters do:
INTELI-POWER 9200 Series Operation
1. ELECTRONIC CURRENT LIMITING
2. VARIABLE SPEED INTELLIGENT COOLING FAN
3. AUTOMATIC THERMAL PROTECTION
4. LOW VOLTAGE PROTECTION
5. HIGH VOLTAGE PROTECTION
6. REVERSE BATTERY PROTECTION
Does the PD-9260 do what the Progressive EMS does? Did I go overboard trying to protect the electrical system or is the PD-9260 converter only for the 12v side of the camper?
