2-in-1 Operation Guide
The NPP series allows you to easily switch the unit's operational mode based on your specific application needs without requiring external programming tools.
| Operation Mode | Configuration Method | Behavior |
|---|---|---|
| Battery Charger Mode | Default Setting (Pins 3 & 4 Open) | Operates using a 3-stage charging curve. Outputs a TTL signal when the battery is fully charged. |
| Power Supply Mode | Short Pins 3 & 4 on the 14-pin connector | Bypasses the charging curve to deliver a constant voltage output. The voltage can be fine-tuned via the built-in potentiometer on the front panel. |
Important Configuration Note: The mode switch is executed by shorting specific pins on the 14-pin control connector located on the front panel. Please refer to the specific model's instruction manual for the exact pinout diagram before configuring your system.
