LES 25-NP

LES 25-NP is a LES series current transducer for the electronic measurement of current: DC, AC, pulsed, with galvanic separation between the primary and the secondary circuit. Standards include IEC 61800-1: 1997, IEC 61800-2: 2015, IEC 61800-3: 2004, IEC 61800-5-1: 2007, IEC 62109-1: 2010, IEC 62477-1: 2012, and UL 508:2013. Typical applications include AC variable speed and servo motor drives, static converters for DC motor drives, battery-supplied applications, uninterruptible power supplies (UPS), switched-mode power supplies (SMPS), power supplies for welding applications, and solar inverters.

• Closed loop multi-range current transducer, voltage output
• Unipolar supply voltage, compact design for PCB mounting
• Very low offset drift, very good dv/dt immunity, CAS footprint compatible
• Primary nominal RMS current is 25A typ at TA = 25°C, UC = +5V, NP = 1 turn, RL = 10kohm
• 18Gohm insulation resistance (measured at 500V DC)
• Frequency bandwidth (±1dB) is 300kHz in at RL = 1kohm
• 8kV impulse withstand voltage 1.2/50μs
• Ambient operating temperature range from -40 to 105°C
