Intrinsically Safe Power Protection Module A.PPEX

Intrinsically Safe Power Protection Module A.PPEX

The A.PPEX module is an intrinsically safe barrier for power lines in certified intrinsically safe electrical equipment or associated apparatus. It can be used where high power and low loss must meet intrinsic safety. The A.PPEX module has an over-current, and an over-voltage protection. There are several variants of the unit, which allows the developer to select the appropriate current limit between 0.7 to 3.3 A and the voltage limit between 5.7 and 12.6 V. The module is produced in a 28 × 20 × 5 mm dual line SMD package.

Features:

  • Limits the voltage and/or current to a specified value (intrinsically safe barrier)
  • 0.8 to 3.3 A over-current protection (OCP) limit*
  • 4.8 to 16 V operating voltage range
  • 4.3 to 4.8 V under-voltage lockout (UVLO)
  • Optional over-voltage (crowbar) protection*
  • 5.7 to 12.6 V tripping voltage*
  • Less than 20 μJ output transient energy before activation
  • Very low self-resistance in normal operation (max. 1Ω)
  • Very low self-capacitance (max. 10.31μF)
  • Auto-retry function
  • Reverse mode: power source connected to output (reverse current is not limited)
  • Switch function: output can be turned off (DISABLE pin)
  • No voltage increasing circuitry inside the module
  • IEC and ATEX certified component: Zone 1 and Zone 2, Zone 21 and Zone 22
  • Package dimensions (W × L × H): 20 mm × 28 mm × 5 mm
  • RoHS Compliant, Pb free

* Depends on the selected part number
