2. Product Parameters
2.1 Electrical Parameter Range
- Voltage Monitoring and Control Range: Capable of monitoring and controlling voltages in the range of [Min Voltage] V to [Max Voltage] V. This wide voltage range allows it to be applied in diverse distribution networks, whether they operate at low - voltage levels for residential and small - scale commercial use or high - voltage levels for industrial and large - scale power distribution. It can accurately detect voltage deviations and take corrective actions to keep the voltage within the acceptable range.
- Current Monitoring and Control Range: Can handle current values from [Min Current] A to [Max Current] A. This enables it to manage the flow of electric current in different types of electrical circuits, from those with low - current loads like household appliances to high - current circuits powering large - scale industrial machinery. It can monitor the current for any abnormal increases or decreases and respond accordingly to protect the equipment and the network.
- Power Factor Regulation Range: Is designed to regulate the power factor within the range of [Min Power Factor] to [Max Power Factor]. By optimizing the power factor, it helps in reducing energy losses in the distribution network and improves the overall efficiency of power utilization. This is particularly important in industrial settings where large inductive loads can cause a poor power factor.
2.2 Communication - related Parameters
- Communication Protocols Supported: Supports standard communication protocols such as IEC 61850 and DNP 3. These protocols facilitate seamless communication with other devices in the power distribution network, including intelligent electronic devices (IEDs), supervisory control and data acquisition (SCADA) systems, and other control units. Through these protocols, the PCD237A101 can exchange real - time data, receive control commands, and report its operational status.
- Data Transfer Rate: Can achieve a data transfer rate of up to [Data Transfer Rate] Mbps. This high - speed data transfer ensures quick and efficient communication, allowing for rapid response to changes in the network conditions. For example, in case of a sudden voltage dip or an over - current event, the device can quickly send the relevant information to the control center and receive instructions for corrective actions.
2.3 Protection - related Parameters
- Overcurrent Protection Threshold: The overcurrent protection is set to trigger at [Overcurrent Threshold] A. When the current in the monitored circuit exceeds this threshold, the device immediately takes action, such as tripping a circuit breaker or sending an alarm signal, to prevent damage to the connected equipment and the network due to excessive current.
- Overvoltage Protection Threshold: The overvoltage protection is activated when the voltage reaches [Overvoltage Threshold] V. Once triggered, it can either regulate the voltage back to the normal range or isolate the affected part of the network to protect against voltage - related damage.
- Under - voltage Protection Threshold: Under - voltage protection comes into play when the voltage drops below [Under - voltage Threshold] V. The device can then initiate actions like load shedding or adjusting the operation of certain equipment to maintain the stability of the network.
3. Product Specifications
3.1 Physical Specifications
- Dimensions: Measures [Width] mm in width, [Height] mm in height, and [Depth] mm in depth. Its compact design makes it easy to install in standard control cabinets, switchgear, or other equipment within the distribution network. This space - saving feature is especially beneficial in areas where space is limited, such as in small - scale substations or within existing electrical infrastructure.
- Weight: Weighs approximately [Weight] g (e.g., as per some sources, around 1000g). The relatively lightweight nature of the device makes it convenient for installation, maintenance, and replacement by technicians. It also reduces the stress on the mounting structures, ensuring long - term stability during operation.
3.2 Environmental Specifications
- Operating Temperature Range: Can function reliably within a temperature range from - [Min Temp] °C to + [Max Temp] °C. This wide temperature tolerance allows it to be deployed in various environmental conditions, from cold regions where outdoor substations may be located to hot industrial areas with high ambient temperatures. In cold - climate areas, it can continue to accurately monitor and control electrical parameters without being affected by the low temperatures.
- Humidity Tolerance: Can withstand relative humidity levels of [Min Humidity]% - [Max Humidity]% (non - condensing). This ensures stable operation in humid conditions, preventing issues such as corrosion of internal components or electrical short - circuits that could impact its performance. In coastal regions or areas with high humidity, the device remains functional and reliable.
- Vibration Resistance: Designed to withstand vibrations of up to [Vibration Level] g in the frequency range of [Min Vibration Frequency] Hz - [Max Vibration Frequency] Hz. This makes it suitable for use in environments with mechanical disturbances, such as near heavy machinery or in mobile power distribution units. In industrial plants with vibrating equipment, the PCD237A101 can maintain its accurate monitoring and control functions without interruption.
- Protection Rating: Has an IP[Protection Rating Number] protection rating. For example, an IP30 rating protects against solid objects larger than 2.5 mm, making it suitable for indoor installation in environments with a moderate risk of foreign object intrusion. If it has a higher - rated protection, such as IP54, it can provide additional protection against dust and water splashing from all directions, making it suitable for more challenging outdoor or industrial environments.
