Model LN2 | Precision Current Transformer | Fault Detection

Models: LN2 | Thousands are in use since 1996 |

Application Description

AC VOLTAGE OUTPUT TRANSFORMER: The Model series LN2 (previously Model 4LN2), uses an internal voltage setting resistor that sets the full scale output voltage to 100mV, 250mV, 333mV, 500mV,1000mV or 1500mV. The removable leg contains a lapped spring loaded core that mates with the precision core in the main housing. Phase displacement is adjusted to within 0.25° AC CURRENT OUTPUT CURRENT TRANSFORMER: The customer’s meter provides the burden resistance. Internal open circuit protection provided. The “burden” resistance is critical for calculating the final ratio error. Due to the core size, the turns ratio must be high to keep the winding current low as possible. Ratios of 1000, 2000 or 3000:1 are standard – see output chart.
