Single phase

Single Phase DIN-Rail Meter

The CA168 - SF57 is a single - phase rail - mounted meter. It is designed to accurately measure electrical energy for various applications, suitable for both commercial and residential use. The meter can be applied to payment scenarios as it is compliant with DLMS and STS. Communication with an optional Customer Interface Unit (CIU) can be carried out via M - bus, PLC, LORA, or RF.

Introduction

Introduction

Main Features

Rated Parameters: 230V, 5(60)A, 50HZ, Class 1.0 accuracy

Split Configuration (if applicable)

Since the CIU is optional, if there is a split configuration, the Metering & Control Unit (MCU) and CIU could potentially be linked through the available communication methods (M - bus, PLC, RF). The CIU could be installed within the consumer’s premises for user - friendly interaction, while the MCU could be placed in a meter cabinet at a suitable location away from the consumer for better management and protection. However, details would be subject to specific requests.
