General Information

• Manufacturer: Siemens AG
• Product Series: SIMOVERT (Siemens Power Conversion Systems)
• Product Type: DC Converter Module (Three-Phase Input)
• Status: Discontinued (Obsolete, legacy component for older industrial systems)
• Target Applications: Power supply for DC loads in industrial machinery, such as auxiliary circuits of motor drives, control systems, and low-power DC actuators.

Electrical Specifications

1. Input Parameters:
   • Input Voltage: 380 - 480 V AC, 3-phase, 50/60 Hz (standard industrial 3-phase power input).
   • Input Frequency Tolerance: ±5% (compatible with minor grid frequency fluctuations).
2. Output Parameters:
   • DC Output Voltage: 513 V DC (rated output, derived from 3-phase full-wave rectification of input voltage).
   • Rated Output Current: 12 A (continuous duty rating for DC load supply).
   • Overload Capacity: Typically 150% of rated current for 1 minute (to handle transient peak loads).
3. Control & Regulation:
   • Voltage Regulation: Analog closed-loop regulation with built-in proportional-integral (PI) controller to maintain stable output voltage (voltage ripple ≤ 5% of rated output).
   • Control Signal Input: 0 - 10 V DC analog reference signal for remote voltage adjustment (optional, based on system configuration).

Protection & Safety Features

• Overcurrent Protection: Automatically shuts down the module when output current exceeds overload capacity, preventing damage to internal components and connected loads.
• Overvoltage Protection: Triggers at 115% of rated DC output voltage to protect against voltage spikes from load transients or input grid surges.
• Undervoltage Protection: Deactivates the module if input AC voltage drops below 85% of the rated input, avoiding unstable operation.
• Over-temperature Protection: Integrated thermal sensor shuts down the module if internal temperature exceeds 85°C, preventing overheating.
• Short-Circuit Protection: Fast-acting electronic protection (response time < 10 ms) to interrupt output in case of a short circuit at the DC load side.

Physical & Environmental Specifications

• Dimensions: Approx. 120 mm (Width) × 200 mm (Height) × 250 mm (Depth) (estimated based on similar SIMOVERT modules, optimized for cabinet mounting).
• Weight: Approximately 4.5 kg (varies slightly by wiring terminals and cooling accessories).
• Mounting: DIN rail or panel mounting (compliant with EN 50022 standard for industrial control cabinets).
• Protection Class: IP20 (dust-protected, suitable for indoor industrial environments with proper enclosure in control cabinets).
• Cooling Method: Natural convection cooling (passive cooling, no internal fans, reducing maintenance needs).
• Operating Temperature Range: 0°C to +40°C (continuous operation; derating by 2% per °C above 40°C up to 50°C).
• Storage Temperature Range: -20°C to +70°C.
• Relative Humidity: 5% - 95% (non-condensing, to avoid moisture-related electrical faults).

Application & Compatibility Notes

• System Integration: Designed for use in legacy industrial systems where stable DC power is required for analog control circuits, such as older SIMOREG DC drive systems or SIMATIC S5 PLC auxiliary power supplies.
• Replacement Options: As an obsolete product, it is commonly replaced by Siemens’ modern SITOP industrial power supplies (e.g., 6EP series) or SIMOVERT DC-Master converters (6RA80 series) for digitalized and more efficient power conversion.
• Wiring Requirements: Requires 3-phase AC input wiring with appropriate fuses (rated 16 A) and DC output wiring sized for 12 A continuous current (minimum 4 mm² copper cable).
