APN & APO Series Power Monitoring Measurement Transducers feature the patented Autophase™ technology, which helps to correct common wiring errors ranging from CT reversal to phase mismatch.
Analog 4–20mA or 0–5/10VDC (proportional to kW) and pulse kWH outputs are available as standard options; RS232 outputs are optional in either configuration.

|
- Provides for reliable measurement
|
- Senses and automatically corrects for errors in CT orientation or mismatches between voltage inputs and CTs, identifying the reversed CTs and mismatched phases
|
- APO/APN Series KWH meters accept inputs from traditional existing 5A CTs or from ProteCT™ 0.333V output CTs, which improve safety and eliminate the need for costly shorting blocks
|
- Installation is simple and efficient
|
- MODBUS option allows for direct network connection without the need for expensive system interfaces
