Description

Product Overview

The GPS6-N4VA2 4P Automatic Changeover Switch (ATS/ACS) is a high-performance 3-in 1-out phase selector designed to ensure uninterrupted power supply. Featuring advanced overvoltage and undervoltage protection, this 110V automatic transfer switch seamlessly switches between three input phases to a single output, safeguarding your critical electrical equipment. Ideal for residential, commercial, and industrial applications requiring reliable phase selection and voltage stability.

Key Advantages

Intelligent Phase Monitoring: Continuously monitors N, L1, L2, and L3 terminals to ensure the output phase is always within safe voltage parameters.
Lightning-Fast Transfer: With a switch delay of <0.2s, your connected devices will experience minimal to zero downtime during phase fluctuations.
Digital Display: Clear, real-time digital readouts for input voltages (L1-in, L2-in, L3-in) and output current (L-out) for easy monitoring.
Customizable Parameters: Easily adjust over/under voltage thresholds and recovery delay times to suit your specific grid conditions.

1. What is the GPS6-N4VA2?
It is a 4-Pole Automatic Changeover Switch (ACS/ATS) that functions as a 3-in 1-out phase selector. It monitors three input power phases and automatically selects the most stable one to output to your load.

2. What functions does it provide?
It provides automatic phase switching, overvoltage protection, undervoltage protection, auto-reclosing, and priority phase return. It acts as a comprehensive safeguard for your electrical system.

3. What are the key parameters for selection?
When selecting this device, the most critical parameters are the rated supply voltage (AC 3*110V), the maximum operating current (63A, 80A, or 100A), and the rapid switching delay (<0.2s).

4. What are the available options?
Currently, you can choose the model based on your maximum operating current requirements: 63A, 80A, or 100A.

5. What standards does it comply with and which market is it designed for?
The product complies with CE and RoHS standards. Given its AC 110V rated supply voltage, it is specifically designed for markets and industrial setups that utilize 110V phase voltage systems.

6. What are the installation precautions?
Always ensure the main power is completely disconnected before wiring. Follow the N, L1, L2, and L3 terminal markings strictly. The device is designed for standard DIN rail mounting. Please read the product manual carefully before installation and operation.
