产品特点 FEATURES

1 Closed loop multi-range current transducer for DC/AC/pulsed current measurement with galvanic isolation between primary and secondary circuits

2 Primary nominal RMS current:15A, measuring range:±51A; Unipolar supply voltage:4.75-5.25V; Voltage output:0.25-4.75V

3 High precision performance: Sensitivity error±0.2%, linearity error±0.1% of IP N; Frequency bandwidth up to300kHz; Step response time 0.4µs

4 Compact PCB mounting design, compatible with LTSR footprint; Reference pin supports Ref IN (0.5-2.75V) and Ref OUT modes

5 Excellent insulation performance: AC test voltage4.3kV (1min), impulse withstand voltage8kV; Case material meets UL94 V0 flame retardant standard

6 Wide temperature adaptability: Operating temp range -40°C~105°C; Storage temp range -55°C~125°C; Primary conductor max temp110°C

7 Key advantages: Very low offset drift, good dv/dt immunity, extended unipolar measurement range

使用场景 APPLICATIONS

1 AC variable speed and servo motor drive systems for real-time current monitoring

2 Static converters in DC motor drive applications

3 Battery-powered devices requiring accurate current measurement

4 Uninterruptible Power Supplies (UPS) for power flow and stability monitoring

5 Switched Mode Power Supplies (SMPS) and welding power supplies

6 Solar inverters for grid-connected or off-grid current sensing

7 Industrial equipment needing galvanically isolated current measurement (e.g., power quality analyzers)

注意事项 PRECAUTIONS

1 Installation requirements: Must be mounted on PCB (minimum CTI of100); Use suitable enclosure to cover conducting parts; PCB hole diameter:1.3mm (primary pins)/0.8mm (secondary pins); Wave soldering max260°C for10s (no clean process)

2 Operating environment: Use in pollution degree2 or better environment; Do not exceed primary conductor temp (110°C) or ambient temp range (-40°C~105°C)

3 Electrical precautions: Supply voltage must stay within4.75-5.25V; Avoid absolute max ratings (UC max7V, IP max300A); Minimum load resistance:10kΩ for Vref/1kΩ for Vout

4 Circuit design tips: Vout can drive up to100nF capacitive load directly (add series Rf for larger loads); Local decoupling (100nF+) near transducer recommended for power supply

5 Safety rules: Ensure conducting parts are inaccessible after installation; Main supply must be disconnectable; Only use products with UL/UR marks

6 Measurement notes: Demagnetize transducer before offset measurement; Magnetic offset depends on primary current value
