The Curtis Model 3501 is a digital instrumentation panel, often referred to as the Always disconnect the main battery pack positive (+)
Position the controller to minimize exposure to dirt, moisture, and aggressive cleaning solvents. Ensure the wiring terminals are easily accessible but shielded from accidental short circuits.
Connects to the main positive DC voltage source. This provides continuous power to maintain memory functions in specific active setups, though standard configurations pull memory retention directly from internal EEPROM. Exiting Menus: : Excellent readability in various lighting,
Lead-acid batteries produce hydrogen gas while charging or discharging, which is highly explosive.
The auto-ranging power supply is a standout feature. It can safely operate on a nominal voltage range from 12V to 80V DC, with a tolerance of ±25%. This gives it a functional safety window of 9V to 100V DC.
: Equipped with four digital inputs and one 1.0 AMP MOSFET output.
: The Battery Discharge Indicator can be adjusted to match the specific discharge curve of your battery type (Lead Acid, Li-ion, etc.).
