The Siemens SIPLUS PSU3400 6AG1332-0TA00-7AY0 is a stabilized 24VDC 2.5A switching power supply engineered for harsh industrial environments. Based on the standard 6EP3332-0TA00-0AY0 with conformal coating, it delivers 85W of regulated DC power in an ultra-compact 32mm wide DIN rail housing — one of the most power-dense designs in the SIPLUS portfolio. It is the ruggedized successor to the discontinued 6AG1931-2BA00-3AA0.

Key Features

• SIPLUS extreme conformal coating protects against corrosive gases (H2S, Cl2, NH3), 100% RH condensation, frost, and salt mist
• Wide operating temperature range: -40 to +70 °C (cold start from -25 °C)
• Ultra-compact 32 mm wide DIN rail housing maximizes panel space utilization
• Wide-range input: 88-264 V AC or 18-264 V DC for flexible system integration
• Stabilized 24VDC output with 85% efficiency
• SELV galvanic isolation for safe low-voltage distribution
• Conformal coating per EN 61086 Class 2

Technical Data

Applications

This ultra-compact power supply is designed for space-constrained automation panels in harsh environments — chemical dosing skids, offshore wellhead control panels, cold climate telemetry stations, and wastewater treatment monitoring. The 32 mm width allows installation on crowded DIN rails alongside controllers and I/O modules, while the conformal coating ensures long-term reliability despite exposure to corrosive atmospheres and condensation. The wide DC input range (down to 18 V) enables battery-backed operation for critical monitoring applications.
