AMETEK Programmable Power Sequoia Series AC Grid Simulator

Overview

The AMETEK Programmable Power Sequoia Series is a full 4-quadrant, bidirectional regenerative AC grid simulator designed for testing grid-connected power electronics. Using SiC power-switching technology, it simulates various power line conditions and disturbances while supporting applications from solar inverters and UPS systems to vehicle-to-grid (V2G) and wind turbine systems.

Key Features

• Full 4-quadrant bidirectional AC source with regenerative capability
• 500 µs time resolution for transient testing
• Dual voltage ranges (0–166V and 0–333V L-N) with optional transformer coupling up to 715V L-N
• High crest factor support for nonlinear loads (e.g., 4.5 rating delivers up to 300 A peak current)
• Non-linear current waveform programming during load mode
• Built-in 5-inch color touchscreen for intuitive menu-driven operation
• Phase coordination among multiple units via LKM/LKS
• Auto-paralleling for multi-chassis configurations and higher power requirements
• Standard interfaces: RS-232, USB, Ethernet (optional GPIB for IEEE-488)
• SCPI command protocol support for integration with automated test systems

Applications

• Solar inverter grid simulation and performance testing
• UPS (Uninterruptible Power Supply) system testing and commissioning
• Vehicle-to-Grid (V2G) and EV power electronic testing
• Wind turbine and renewable energy system simulation
• Avionics power system testing and compliance certification
• Power Hardware-In-the-Loop (PHIL) simulation of electrical systems
• Grid fault and disturbance condition testing
