Dimensions and Specifications
The PFC-50 and 75 series chargers weigh approximately 42 pounds (19 kg)
The outermost dimensions including foot flanges and front amps knob are
approximately 22” L x 12.5” W x 7” H (559mm x 318mm x 177mm)
Allow at least 25” total length (635mm) to include the power cables
Input Voltage Range : 100 to 240VAC 40-80Hz computer grade pure sine wave
Output Voltage Range : 12 to 450VDC ( +/- 1 volt )
Operating Temp Range : -20° F to +120° F ( -28.8° C to +48.8° C )
Power Consumption : Up to 12.0kW ~ PFC-50 and PFC-50B / 18.0kW ~ PFC-75
The 50 in PFC-50 is indicative of the number of amps that the charger is rated to
draw from the AC line. A PFC-75 can draw up to 75 amps. Unlike some other
chargers, this is the rated continuous load and all units are thoroughly tested to their
rated limits before leaving Manzanita Micro. The PFC-75 model includes a current
meter on the front which displays the amount of current (amps) that the charger is
drawing from the AC line. This allows the user to tune the charger precisely for the
maximum allowable amps for the outlet they are plugged into.
The charger can be mounted in any orientation as long as it has adequate airflow
and is protected from sucking in moisture and debris. All chargers are designed to
automatically cut back current when they exceed their temperature limits. If the
yellow limits light starts blinking and power is reduced, it is likely more airflow is
needed. The fans push the air out through the front of the charger therefore,
mounting the unit such that the control face is pointing upward this is probably the
most efficient since heat rises. It is important to use properly sized bolts for all four
mounting holes in order to mount the unit. Grade 5 or Grade 8 fasteners are the
