1. Key Parameters

• Product Model: ES2000-9725
• Product Series: ABB ES2000 Series Industrial Current Sensors (Hall-Effect AC/DC Measurement)
• Core Function: Measures AC/DC currents with high precision; converts current signals to standardized analog/digital outputs; provides overcurrent detection; enables real-time current monitoring; integrates with PLC/DCS/signal conditioning systems; ensures electrical isolation between primary (current-carrying) and secondary (measurement) circuits
• Measurement & Electrical Specifications:

  Parameter	Details	Performance Metrics
  Measurement Range	- AC: 0~500A rms (50/60Hz, 40~400Hz frequency range) - DC: 0~600A (continuous); 1200A (peak, 10ms) - Accuracy Class: 0.5 (AC, 50~100% of full scale); 0.7 (DC, 20~100% of full scale) - Linearity Error: ≤±0.3% of full scale (AC/DC)	Wide range covers most industrial applications (e.g., 500A motor drives, 600A battery banks); 0.5 accuracy class meets energy metering and control requirements
  Output Signals	- Analog: 4~20mA DC (isolated, load resistance ≤500Ω) - Digital: Open-collector overcurrent alarm (threshold configurable: 110%~150% of full scale) - Isolation Voltage: 2.5kV AC (primary-secondary, 1 minute) - Response Time: ≤10μs (step current change)	Isolated 4~20mA output prevents ground loops; fast response time enables real-time fault detection (e.g., motor overloads)
  Power Requirements	- Supply Voltage: 12V DC~24V DC (±10%) - Power Consumption: ≤1.5W (24V DC) - Protection: Reverse polarity (up to 30V DC); overvoltage (30V DC clamp)	Wide voltage range suits industrial control power supplies; reverse polarity protection prevents damage from wiring errors

• Mechanical & Environmental Specifications:

  Parameter	Details	Performance Metrics
  Mechanical Design	- Dimensions: 85mm (W) × 60mm (H) × 35mm (D) - Mounting Type: DIN rail (35mm, EN 50022) or panel mount (via threaded holes) - Current Input: Split-core (openable) design (accepts conductor diameter ≤25mm) - Housing Material: Flame-retardant thermoplastic (UL 94 V0) - Weight: Approximately 180g	Split-core design enables retrofitting on existing cables (no need to disconnect power); compact size fits tight control cabinet spaces
  Environmental Ratings	- Operating Temperature Range: -40℃~+85℃ (-40℉~185℉) - Storage Temperature Range: -55℃~+100℃ (-67℉~212℉) - Humidity Tolerance: 5%~95% RH (non-condensing, 40℃) - Vibration Resistance: 10~2000Hz, 2g acceleration (IEC 60068-2-6) - Shock Resistance: 50g (11ms half-sine, IEC 60068-2-27) - EMC Compliance: EN 61326-3-1 (emission: Class B; immunity: Level 3)	Extreme temperature range (-40℃~+85℃) suits harsh environments (e.g., desert solar plants, arctic pipelines); Level 3 EMC immunity resists interference from VFDs/motors

• Compliance Standards: CE, UL 508, CSA C22.2 No.14, IEC 61869-1 (current transformers), RoHS, ISO 9001 |

2. Core Features

• Dual AC/DC Measurement: Covers 0~500A AC (rms) and 0~600A DC (continuous)—eliminates the need for separate AC and DC sensors, simplifying inventory for mixed electrical systems (e.g., hybrid industrial drives, battery-backed UPS).
• High Precision & Fast Response: 0.5 accuracy class (AC) and ≤10μs response time—ensures reliable current tracking for energy metering (e.g., ISO 50001 compliance) and rapid detection of transient faults (e.g., short circuits, motor inrush).
• Split-Core Retrofit Design: Openable core accepts conductors up to 25mm diameter—enables installation on live cables without power shutdown, reducing downtime during retrofits (e.g., upgrading motor control panels).
• Electrical Isolation: 2.5kV AC isolation between primary and secondary circuits—protects sensitive control systems (e.g., PLCs, DCS) from high-voltage transients, enhancing operator and equipment safety.
• Configurable Overcurrent Alarm: Digital open-collector output with 110%~150% full-scale threshold—triggers immediate alerts for overloads (e.g., motor jams, battery overcharging), enabling proactive fault mitigation.
• Extreme Environment Durability: -40℃~+85℃ operating range, 2g vibration tolerance, and UL 94 V0 housing—functions reliably in harsh conditions (e.g., mining, oil & gas, outdoor renewable energy systems) without performance loss.
• Seamless System Integration: Isolated 4~20mA analog output—directly connects to PLCs (e.g., ABB AC500), DCS, or signal conditioners; no additional isolation modules required, reducing system complexity and cost.

3. Application Fields

• Industrial Automation & Motor Control: Current monitoring for drives:
  • AC Motor Drives: Measures input/output current of ABB ACS880 drives (0~500A AC)—0.5 accuracy class ensures optimal drive tuning; fast response time detects overloads (e.g., mechanical jams) to prevent drive damage.
  • DC Servo Systems: Tracks armature current of DC motors (0~600A DC)—split-core design enables retrofitting on existing cables; overcurrent alarm triggers emergency stops for servo overloads.
• Renewable Energy Systems: Grid & battery current measurement:
  • Solar Inverters: Measures AC output current (0~500A rms) from solar inverters to the grid—high accuracy supports energy yield calculation; -40℃~+85℃ range tolerates desert/arctic solar farm temperatures.
  • Battery Energy Storage (BESS): Monitors DC charging/discharging current (0~600A DC) of battery banks—configurable overcurrent alarm prevents overcharging; isolation protects BMS from high-voltage battery transients.
• Power Distribution & UPS: Load current tracking:
  • Industrial Switchgear: Measures current in 3-phase power distribution circuits (0~500A AC)—4~20mA output integrates with energy management systems (EMS) for load balancing; split-core design simplifies switchgear retrofits.
  • UPS Systems: Tracks DC input current (battery) and AC output current (load)—dual AC/DC measurement eliminates separate sensors; overcurrent alarm detects UPS overloads (e.g., server power spikes).
• Transportation & Heavy Equipment: Mobile current sensing:
  • Electric Vehicles (EV) Charging Stations: Measures AC charging current (0~500A rms) or DC fast-charging current (0~600A DC)—EMC immunity resists interference from EV electronics; compact size fits charging station enclosures.
  • Mining Machinery: Monitors current of hydraulic pumps and traction motors (0~500A AC/DC)—2g vibration tolerance withstands machinery vibrations; -40℃ operating range suits underground mines.
