Siemens 6SE7038-6GL84-1JA1 SIMOVERT MASTERDRIVES PSU2 Power Supply Module
High-Performance Power Supply Module for J-M Design Masterdrives
High-Power PSU2 Module: Designed for the largest MASTERDRIVES chassis (Design J-M), providing the power foundation for drives in the 315kW-400kW class
Wide Input Voltage Range: Supports 3-phase AC 380-480V / 660-690V and DC 510-620V / 890-930V, accommodating diverse industrial power environments
Stable DC Output: Delivers regulated 24V DC at 20A for reliable operation of internal electronics and cooling systems
High Efficiency: Achieves >92% conversion efficiency, reducing energy loss and heat generation
Robust Protection: Integrated overvoltage, undervoltage lockout, overcurrent, overtemperature, and fan failure monitoring
Critical for Drive Operation: Directly powers the CUVC/CUMC control board, provides isolated power for IGBT gate drivers, and drives high-power cooling fans – failure means complete drive shutdown
Industrial-Grade Construction: Operating temperature range of 0°C to 60°C, suitable for demanding industrial environments
