Introduction

The PM-4324D series multi-circuit power meter monitors up to 8 three-phase circuits or 24 single-phase circuits, or any combination of single or three-phase circuits. The PM-4324D series can measure up to 24 currents via external Current Transformers (CTs). This flexibility makes the PM-4324D series perfect for multi-tenant facilities such as residential projects, office buildings and shopping malls. This compact instrument is designed to easily fit into existing panelboards or be flush mounted nearby, thus eliminating the need for expensive retrofit projects or for allocating extra space for the device. The digital temperature sensor function that provides one port for 2- or 3 wire DS18B20 digital temperature sensor input. This meter has LCD display shows power.

Application

• Generator monitoring
• Switchgear distribution systems
• Energy Management
• Power quality analysis
