MP and EL industry current sensors
| Utilisation Sensors to measure d.c., a.c. or pulsating currents with a galvanic insulation between primary and secondary circuits.Type MP25P1: the rating (from 5 to 25A) is determined via a combination of the primary connections (see table: "Arrangement of primary terminals and related characteristics"). |  |

| General data Direction of the current: ● MP25P1 Type: A primary current flowing from pins 1- 5 to pins 6-10 results in a positive secondary output current from terminal M. ● EL Type: A primary current flowing in the direction of the arrow results in a positive secondary output current from terminal M. Fixing By soldering pins on printed circuit board. Primary connection ● MP25P1 Type: By 10 soldering pins. ● EL Type: Hole for primary conductor (the temperature of the primary conductor in contact with the case must not exceed 100°C) ● EL…BB type: Primary bar included. | Secondary connection 3 soldering pins. Unit packing ● MP25P1 type: 40 per pack. ● EL type: 50 per pack. ● EL…BB type: 25 per pack. |
