Product Description

The SWP-LED Series AC/DC Electrical Quantity Centralized Display and Control Meters are designed for measuring sampled signals from voltage and current transformers, as well as frequency, voltage, current, power factor, and active power. The active power is calculated as:

• Single-phase active power: $P=U\cdot I\cdot \cos \Phi$

• Three-phase active power: $P=$ (formula depending on wiring)

2. Main Features

1. Flexible Input Range – The input signal range can be changed freely. Using advanced jumper-free technology, simply set the internal parameters to meet site requirements.

2. Output Options – Can include one analog signal output or relay alarm output, suitable for various measurement and control applications.

3. Full Isolation Technology – Ensures reliable operation in industrial environments.

4. Multi-Parameter Display – SWP-E series instruments can display up to 4 sets of AC electrical parameters simultaneously.
