Bourns 2510 & 2520 Data and Signal SPDs

Bourns 2510 and 2520 Data and Signal Surge Protective Devices (SPD) are designed to protect 1-pair and 2-pair data lines with common reference potential in data, signal, and communications systems from electrical surges. The SPDs feature a 20kA max discharge current rating and a 100MHz cut-off frequency rating. The SPDs offer a non-interruptible signal transmission during module exchange and pluggable surge protection for DIN-rail mounting. Bourns 2510 and 2520 Data and Signal SPDs are IEC 61643-21 compliant and ideal for telecommunications, low-voltage alarm circuits, high-frequency transmission systems, analog/digital communications, and RS-232, RS-422, and RS-485 interface applications.

Features

  • Dataline protector per UL 497B standard
  • Non-interruptible signal transmission during module exchange
  • Two-stage protection circuit limits transients associated with gas discharge tubes and diodes
  • Pluggable surge protection for DIN-rail mounting
  • Impulse current capacity up to 2.5kA, 10μs to 350μs
  • IEC 61643-21 compliant (category D1/C1/C2/C3)
