** Special units have a suffix of B XX after the part number. The float value of the charge controller is XX. For example PT 12/24 - 5 B8.4 will charge a li-ion battery to 8.4 V from a nominal 12 V solar panel. Note that the charge current increase by the ratio of approx. 15/8.4. Thus a 1 amp 12 V nominal solar panel will charge the li-ion battery at approx. 1.78 amps.
Temperature Compensation:
- Uses a National LM335Z temperature sensor available from Solar Converters Inc. as Model TC-2.
LVD Control:
- Short these terminals together with a relay contact, (rated 32 V @ .1 A - be careful of dry contacts) or a similiarly rated transistor and the LVD will open; forming an effective load disconnect.
Used for Battery Backed Solar Water pumping as a Float Switch Control.
