DEIF IPM-1 Intelligent Power Manager

I. Overview

• Synchronous Multi-Loop Power Monitoring: Supports power parameter collection for 8 independent loops (voltage, current, active power, reactive power, power factor, energy metering). The voltage measurement range is AC 85V-480V (50/60Hz), and the current measurement range is 0-500A (when used with CT). The measurement accuracy is ±0.5% FS (for active power), the sampling rate is 1kHz per loop, and the synchronization error between loops is ≤100μs.
• Dynamic Load Distribution and Overload Protection: Built-in load priority algorithm enables dynamic power distribution based on preset priorities (e.g., "production equipment ＞ auxiliary equipment ＞ lighting"). When the total power exceeds 10% of the rated value, low-priority loads are cut off within 100ms. It is equipped with overcurrent (1.2 times the rated current) and overpower (1.1 times the rated power) protection, with a response time of ≤50μs to prevent equipment damage.
• Energy Efficiency Analysis and Data Storage: Calculates real-time energy consumption (kWh) and energy efficiency ratio (PUE) for each loop, and supports the generation of daily/hourly/monthly energy efficiency reports. Built-in 128MB Flash memory stores 1 year of historical data (non-volatile even when power is off), which can be exported for analysis via communication interfaces.
• Multi-Protocol Communication and Collaborative Control: Supports RS485 (Modbus RTU), CANopen, and Ethernet (Modbus TCP) communication. The data interaction delay with the main controller is ≤10ms. It can work with DEIF controllers to achieve "distributed power management" (e.g., two or more modules collaboratively control over 20 loops).
• Industrial Environment Adaptability: Adopts a metal shielded housing (shielding effectiveness ≥40dB), with an operating temperature range of -25℃ to 70℃ and an IP20 protection rating (suitable for cabinet installation). Its vibration resistance complies with the IEC 60068-2-6 standard (10-500Hz, 1g acceleration). In strong electromagnetic industrial environments (e.g., near frequency converters), the power measurement fluctuation is ≤±0.2% FS.

III. Functional Features

1. 8-Channel High-Precision Synchronous Monitoring: Solving Power Measurement Deviation Issues

• 8-Channel Integration for Cost Reduction and Efficiency Improvement: A single module monitors 8 loops, replacing 8 traditional single-phase power meters. In a factory workshop, the number of power monitoring devices was reduced from 16 to 2, cutting cabinet space usage by 80%. It supports flexible single-phase/three-phase configuration (e.g., 6 single-phase + 1 three-phase), adapting to mixed power supply scenarios (e.g., workshops with both 220V equipment and 380V motors) without additional modules.
• ±0.5% FS High-Precision Guarantee: The active power measurement accuracy reaches ±0.5% FS. In a data center, the IPM-1 monitors UPS output power, reducing the error from ±2% (traditional meters) to ±0.3%, avoiding overload misjudgment caused by measurement deviations (reducing 1 false shutdown per month and cutting losses by 100,000 yuan). With current/voltage measurement accuracy of ±0.2% FS, it meets industrial metering requirements (e.g., internal energy allocation in factories) when used with Class 0.1 CT/PT.
• 100μs Synchronous Collection: The synchronization error of 8-loop collection is ≤100μs. In a ship's power system, the IPM-1 synchronously monitors the output power of 3 generators, reducing the power balance calculation error from ±2% to ±0.5% and ensuring more uniform generator load distribution (load deviation exceeding 5% shortens generator service life).

2. Dynamic Load Distribution: Avoiding Power Overload and Energy Waste

• Priority-Driven Load Cut-Off: With preset load priorities (e.g., "CNC machine tools ＞ air conditioners ＞ lighting"), when the total power exceeds the threshold (e.g., 95% of the transformer's rated value), low-priority loads are cut off within 100ms. In an automobile factory during peak production, cutting off 2 air conditioning loops prevented transformer overload tripping (traditional systems lack this function, causing 1 trip per month and 2 hours of production downtime, with losses of 150,000 yuan).
• Load Recovery with Impact Prevention: Supports "gradient recovery" (e.g., after load cut-off, when total power drops to 80% of the safe value, loads are restored gradually by priority). After UPS switching in a data center, the IPM-1 restored low-priority loads in 3 steps (500ms intervals), avoiding UPS restart caused by power impact (traditional direct recovery easily triggers inrush current).
• Energy Efficiency Data Visualization: Calculates real-time loop energy consumption and PUE (e.g., workshop PUE = total energy consumption / production equipment energy consumption), and generates daily/monthly reports via DEIF monitoring software. A factory found that auxiliary equipment (e.g., fans) accounted for 20% of energy consumption; optimizing operation time reduced annual electricity use by 30,000 kWh.

3. Strong Anti-Interference and Wide-Temperature Design: Adapting to Harsh Industrial Environments

• Full-Link Electromagnetic Interference Resistance: Metal housing shielding (≥40dB) + differential signal collection + software filtering (50Hz/60Hz notch filter). Near 10kV frequency converters (electromagnetic radiation 50V/m), power measurement fluctuation was reduced from ±1% to ±0.2%, eliminating interference-induced false data (e.g., power value jumps).
• -25℃~70℃ Wide-Temperature Adaptation: Low-temperature resistant capacitors (starting at -40℃) for cold conditions and ceramic-encapsulated chips (withstanding 125℃) for high temperatures. In a northern factory with -15℃ workshop temperatures in winter, the IPM-1 operated stably (traditional modules tend to crash below 0℃); in ship cabins with 65℃ temperatures in summer, the module showed no performance degradation.
• Fast Overcurrent/Overvoltage Protection: Overcurrent protection response ≤50μs. In a motor control loop, motor stalling caused current to double the rated value; the IPM-1 triggered a relay to cut off power, preventing motor burnout (traditional circuit breakers have a response time ≥100ms, which would overheat motor windings).

4. Multi-Protocol Collaboration and Data Storage: Simplifying System Integration and O&M

• Multi-Protocol Compatible Integration: Supports Modbus RTU/TCP and CANopen, and can be directly connected to factory SCADA systems (e.g., WinCC, Intouch). A factory uploaded IPM-1 data to the central control room via Modbus TCP, shortening integration time from 3 days to 1 day. Working with DEIF controllers (e.g., AGC PM 300), it enables distributed power management (e.g., 2 IPM-1 modules collaboratively controlling 16 loops).
• 1-Year Historical Data Storage: 128MB Flash stores 1 year of energy consumption data, supporting hourly/daily/monthly queries. A factory identified an energy consumption peak at 9 AM on Mondays (due to centralized equipment startup) through historical data; adjusting the startup sequence (staggering by 10 minutes) reduced peak power by 10% (saving 20,000 kWh annually). Data is non-volatile, avoiding statistical interruptions caused by power outages.
• Visualized O&M: Real-time power curves, historical trends, and fault logs can be viewed via DEIF Power Management Software, eliminating the need for on-site inspections by O&M personnel. A data center remotely monitored 10 IPM-1 modules, improving O&M efficiency by 50%. During faults (e.g., overcurrent), power data at the fault moment is automatically recorded, facilitating traceability analysis (e.g., determining whether the fault is caused by equipment failure or load mutation).
