PFC-50 PFC-50B PFC-75 Charger Owner’s Manual Rev 0.
PFC-50 BATTERY CHARGER MANUAL rev 0.1 General Overview The Manzanita Micro PFC-50 series is a unique line of powerful, efficient battery chargers. The chargers will run off of any voltage from 100 up to 240 AC These chargers can be set to run automatically when plugged in yet they also have far more user adjustable functions than other electric vehicle chargers. Every model is user adjustable to charge batteries from 12 to 450 Volts.
Dimensions and Model Ratings The PFC-50 series chargers weigh in at approximately 42 pounds and reside in a box that is 19.5 x 10.5 x 6.5 inches. The 50 in PFC-50 is indicative of the number of amps that the charger is rated to draw from the AC line. Unlike some other chargers this is the rated continuous load and all the chargers are thoroughly tested to their rated limits before leaving Manzanita Micro.
Charger Operation figure 02: PFC-50 Layout Turning the Charger On and Off There is an ON/OFF Breaker to the left of the blue user control panel at the top of the charger. This breaker is the main switch to turn the charger on or off. If ever there is a concern while charging first shut off this breaker switch.
User Control Panel The user interface panel is the long blue panel with yellow text near the top of the charger. The only thing most users need be concerned with are the LED indicators, the VOLTS TRIM and the adjustable AMPS knob. Below are explanations of each feature in order from left to right. Refer to figure 02 for specific locations. “VOLTS TRIM” This controls the peak DC voltage ceiling that the charger will allow the batteries to reach before limiting the current.
VOLTS TRIM CALIBRATION: Try to make sure your battery pack is fully charged before adjusting (or else you will have to continually monitor it and make more adjustments). 1. Turn the amps knob all the way down (full counterclockwise). 2. Make sure the charger is plugged into the battery pack and that there are no open breakers or open fuses in the DC battery circuit. 3. With the charger’s AC breaker switch in the OFF position, plug the charger into the AC power outlet. 4.
“REG BUSS” This is the 6 pin RJ jack where the BMS communication line plugs into the charger. This port allows the individual battery regulators to communicate with the charger. NOTICE! If your vehicle is equipped with a Battery Management System, Ensure that the reg buss data cable is fully plugged into the charger whenever the vehicle is charging. The communication data cables are hooked to the regulators in a daisy chain fashion.
might need to turn down the charger if there are other loads on the branch circuit (example: A stereo and a computer are running on the same 15 amp circuit). “LIMITS” - Yellow LED The yellow LIMITS LED indicates that the charger has reached its peak voltage limit. This should happen only at the end of the charge cycle when all the batteries are fully charged.
The red and white dip switch module is on the upper right end of the charger. This is a bank of 8 switches and they are numbered starting with #1 on the far right. NOTICE! Adjusting these switches can cause the charger to perform in an undesirable manner. Please be sure you understand these switch features before changing them. Dip Switch Guide: 1. Engages timer at peak voltage limit set point. This switch should be ON 2. Starts timer as soon as the charger is turned on. This can be used for timed charging.
