Function
| Function | Description |
| Multi-Circuit DC Measurement | Measures DC voltage, current, power, and energy for up to 12 single-phase circuits. Voltage range: DC -48V (nominal). Current input via Hall sensors with 5V output. Accuracy: voltage/current Class 0.5, power Class 1.0. Resolution: 0.01V, 0.01A, 0.01kW, 0.01kWh. |
| Digital Inputs | 6 channels: 2 active wet contact inputs (AC 220V) for mains/generator status, and 4 passive dry contact inputs for breaker or equipment status monitoring. |
| Relay Outputs | 2 channels of normally open relay contacts. Contact capacity: AC 250V/3A or DC 30V/3A. Supports remote control and alarm output modes. |
| Temperature & Humidity Monitoring | 4 NTC temperature sensors, range -20~100℃ (±2℃). One温湿度 sensor measures ambient temperature (-20~100℃, ±2℃) and humidity (20-90%RH, ±5%RH). |
| Hall Sensor Power Supply | Provides ±12V DC output to power up to 12 Hall current sensors. Eliminates need for external power supplies for sensors. |
| Mains Monitoring | One channel AC input detection (DC 0-5V) for monitoring mains power status. Configurable alarm thresholds. |
| Data Storage | Historical data storage: 60-minute interval (records), daily records, meter reading day records. Alarm history stores up to 500 events. |
