The "LEM Module LV 25-P" (Normal Current 10 mA) is a sensor for electronic measuring of voltages: DC, AC, pulsed...with galvanic isolation between the primary (high current) and the secondary (electronic) circuit. For voltage measurements, a current proportional to the measured voltage must be collected through an external resistor R1 which is selected by the user and installed in series with the primary circuit of the LV 25-P.

Operating range (recommended): taking into account the resistance pf the primary winding (which must remain low compared to R1, in order to keep thermal deviation as low as possible) and the isolation, this transducer is suitable for

measuring nominal voltage from 10 to 500 volts.

Main advantages:

• Measurement of all voltage waveforms (DC, AC, Impulse)
• High accuracy, excellent dynamic performances.
• Response time 40 micro second for R1 equal to 25 Kohm
• Linearity: better than 0.2%
• High immunity to external interference
• High reliability: MTBF 1,000,000 hours

Typical applications:

AC variable speed drives and servo motor drives, Static converters for DC motor drives, Battery supplied applications, Uninterruptible power supplies, Power supply for welding application.
