Homage Ups Circuit Diagram 1000va Pdf -

Two 12V, 7Ah to 9Ah lead-acid batteries connected in series. The circuit monitors individual battery voltage to prevent over-discharge.

A: Standard Homage uses Red (Battery +) , Black (Common Ground) , and sometimes a Yellow (Center tap for 12V) . The diagram will confirm. Homage Ups Circuit Diagram 1000va Pdf

| Sensor | Purpose | Typical IC/Pin | |--------|---------|----------------| | Mains AC presence | Detect blackout | Optocoupler (PC817) input from mains | | Battery voltage | Determine charge/discharge state | ADC pin of MCU (e.g., PIC16F72) via resistor divider | | Inverter current | Overload/fault | Shunt resistor amplified by LM358 | | Temperature | Fan control, overheat protection | Thermistor (10k NTC) | Two 12V, 7Ah to 9Ah lead-acid batteries connected in series

The microcontroller (often a PIC16F72, HT46R23, or a dedicated SG3525 + logic gates in older units) performs: | Sensor | Purpose | Typical IC/Pin |
