产品特点 FEATURES
1
Brand: LEM (莱姆), Model: DHR200 C420
2
Function: Electronic measurement of DC and distorted AC waveform currents, with galvanic isolation between primary (power) and secondary (measurement) circuits
3
Output: True RMS 4-20mA DC signal
4
Primary electrical parameters: Nominal DC & AC current (I_pn) 200A, maximum peak AC current (I_pk)800A
5
Electrical specifications: Load resistance <300Ω, supply voltage range +20V DC to +50V DC, current consumption ≤30mA + output current, output current limitation <25mA
6
Performance indicators: Accuracy ±1% of I_pn at 25°C (excluding offset), linearity error ±1.0% of I_pn, output offset ±1.0mA at 25°C, frequency bandwidth DC to 20,000 Hz (±1dB)
7
Isolation characteristics: Rated isolation voltage300V (reinforced isolation per IEC61010-1), impulse withstand voltage4.0kV, creepage distance7.2mm, clearance distance7.3mm
8
Mechanical design: Large aperture compatible with cables up to0.52mm², panel mounting (M4 screws, torque0.75Nm ±20%), protection degree IP20
9
Certifications: CE, RoHS, UL recognized,5-year warranty
使用场景 APPLICATIONS
1
VFD controlled loads: Monitor the operation status of VFD outputs and attached loads (e.g., motors)
2
SCR controlled loads: Accurate measurement of phase angle fired or burst fired currents (faster response than average measurement)
3
Switching power supplies and electronic ballasts: True RMS sensing for precise power measurement
4
Energy and automation domain: Industrial energy management systems, factory automation equipment, building power monitoring systems
注意事项 PRECAUTIONS
1
Installation and operation must be performed by qualified personnel with appropriate training
2
Observe all relevant national regulations during installation and operation
3
Use the transducer in equipment complying with applicable standards and safety requirements
4
Beware of electrical shock: Some parts may carry hazardous live voltage; take necessary protective measures
5
Do not operate if the jaw opening (split core version) is open or the enclosure is not closed
6
Disconnect main power before installation/maintenance unless no live parts are nearby and regulations are followed
7
Optimal dynamic performance when primary busbar fully fills the aperture
8
Primary busbar temperature must not exceed80°C
