Highlights

Meet the SL1200A Series Scienlab Regenerative 3-Phase AC Emulator

The SL1203A is a 600 VAC regenerative three-phase AC emulator for higher-power inverter, EV, and EVSE charging test applications. A simple upgrade adds low-latency, real-time grid simulation for power-hardware-in-the-loop applications. It delivers up to 90 kW of AC power, 130 kVA apparent power, and 125 A. Its regenerative, bidirectional architecture returns energy to the facility rather than dissipating it as heat, helping reduce energy use and cooling requirements.

  • New: Add low-latency, real-time grid simulation for power-hardware-in-the-loop applications with a simple upgrade.
  • Supports three-phase AC testing up to 600 V line-to-line, 125 A, 90 kW, and 130 kVA.
  • Provides 600 VAC output for higher-power inverter, EV, and EVSE charging tests.
  • Returns energy to the facility through a fully regenerative, bidirectional power architecture.
  • Automates IEEE 1547 grid-integration tests, including anti-islanding, with the Grid Integration Test Suite.
  • Configure and operate the SL1203A quickly with the intuitive soft front panel.
  • Use a complete Keysight solution that combines the SL1203A hardware, software, consulting, and worldwide support.
