Reliance Electric SA3000DC17.5 AutoMax SA3000 DC-AC Power Module

Overview

Key Features

1. Medium‑Power DC‑AC Conversion: Converts 621 VDC to 460 VAC three‑phase, 17.5 A continuous output, ideal for 10–15 HP motors.

2. Compact Industrial Design: Rugged metal enclosure, vibration‑resistant components, and small footprint for space‑constrained control cabinets.

3. Forced‑Air Cooling: Integrated fan maintains safe temperatures during 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 for quick troubleshooting.

6. Seamless Integration: Compatible with AutoMax PMI racks, processors, I/O, and SA3000DC series rectifiers (e.g., SA3000DC070).

7. High Short‑Circuit Withstand: 10 kA symmetrical RMS rating for electrical fault durability.
