Description

Siemens 7KG7750-0AA01-0AA1/CC Multi-functional Power Meter

Product Dimensions：

The Siemens 7KG7750-0AA01-0AA1/CC is a high-precision digital power monitoring device from the SICAM P50 family. Designed for panel-door flush mounting, it measures, monitors, and records electrical parameters in medium- and low-voltage power distribution systems.

Product Detailed Description

The 7KG7750-0AA01-0AA1/CC (SICAM P50) is a compact 96 \times 96 mm power meter featuring an integrated graphic display and dynamic measurement capabilities. It measures basic electrical quantities (voltage, current, power, frequency) alongside power quality metrics like total harmonic distortion (THD) up to the 19th harmonic.

Equipped with an RS485 serial communication interface, it natively supports standard industrial protocols, including Modbus RTU/ASCII and IEC 60870-5-103, enabling easy integration into SCADA, energy management (EMS), or substation automation systems.

Technical Parameters

Product Advantages

• High Measurement Precision: Class 0.5S active energy accuracy ensures reliable billing-grade monitoring and energy balancing.
• Power Quality Insights: Detects wave distortion, phase angles, and individual harmonics up to the 19th harmonic to safeguard sensitive equipment.
• Versatile Communication: Supports both industrial automation (Modbus) and utility substation standards (IEC 60870-5-103) on a single RS485 bus.
• Integrated Logic & Limits: Features programmable limit monitoring and basic internal logic routines to trigger binary outputs for local alarming or control actions.
• Clear Interface: Features a high-contrast graphics display for easy localized reading and fast on-device parameter configuration.

Important Considerations (Precautions)

• CT/VT Wiring Ratios: Ensure current transformers (CTs) and voltage transformers (VTs) are correctly wired and their secondary ratios are configured accurately in the meter setup to avoid incorrect readings.
• Front Panel Sealing: The front panel carries an IP41 protection rating by default. If installed in harsh or washdown outdoor environments, use an additional protective enclosure door or gasket.
• RS485 Bus Termination: When connecting multiple SICAM P50 meters in a daisy-chain network, ensure the two physical ends of the RS485 segment are properly terminated with 120-ohm resistors to prevent communication errors.
• Electrical Safety: Always de-energize the measuring circuits and short-circuit CT secondary terminals before servicing the rear connections of the unit.

Product Applications

• Substation Automation: Monitoring feeder lines, transformers, and switchgear status via IEC 60870-5-103 communication.
• Industrial Energy Management: Tracking power consumption, peak demand, and power factor across large industrial plants.
• Commercial Buildings: Tenant sub-metering and power quality analysis in data centers, hospitals, and high-rise facilities.
• Power Quality Auditing: Identifying line harmonics and voltage imbalance issues before they disrupt operations.
