Operating Characteristics
Flexcharge NC25A-12 (24,36,48)
Allowable Battery Voltage on Sense Wires
12V Systems
(Multiply by 2, 3, or 4 for 24V, 36V, or 48V Systems)
Standby/Operating Current of the Controller
Short Term Over-Current (1/2 Second Maximum)
Total Charging Efficiency
Insertion Loss Resistance (Ohms)
Charge Divert Over Current (1/2 Second)
Transient Surge Protection (20uS)
NOTE: this is not a MPPT controller. For solar panel use do not series the panels for higher
voltage inputs. This will reduce the amperage input of the panels to the batteries.
