Reliance Electric SA3000DC70 AutoMax SA3000 DC‑AC Inverter Power Module

Overview

Key Features

1. Medium‑Power DC‑AC Conversion: Converts 621 VDC to 460 VAC three‑phase, 70 A continuous output, suitable for 50–60 HP motors.

2. Rugged Industrial Design: Heavy‑duty metal enclosure and vibration‑resistant components ensure durability in manufacturing settings.

3. Forced‑Air Cooling: Integrated fan maintains optimal temperature during full‑load continuous operation.

4. Comprehensive Protection: Overvoltage, undervoltage, overcurrent, short‑circuit, overtemperature, and ground‑fault protection.

5. Diagnostic LEDs: Front‑panel indicators for DC bus status, run mode, and fault codes to speed up troubleshooting.

6. Seamless Integration: Compatible with AutoMax PMI racks, processors, I/O, and SA3000DC series rectifiers.

7. High Fault Withstand: 10 kA symmetrical RMS short‑circuit rating for electrical safety.
