LP-COM/A Surge Protector for AC/DC Power Supplies

Model LP-COM/A

LP-COM/A series surge protectors for AC/DC power supplies from 5 V to 230 V, fitted at the front end of computer systems, modems and signal control equipment, with series or parallel connection, 10 kA maximum discharge current and DIN-rail mounting.

Overview

About the LP-COM/A Surge Protector for AC/DC Power Supplies.

The LP-COM/A series are surge protective devices for AC/DC power supply lines. Fitted at the front end of power supply equipment such as computer systems, modems and signal control circuits, they protect against overvoltage arising from lightning strikes or mis-operation. Six models cover rated working voltages from 5 V to 230 V. Each unit has a large flow capacity with low residual voltage and no leakage current to ground, and built-in double lightning protection technology. It connects in series or in parallel, so one design suits a wide range of power systems.

Features

  • Six voltage ratings: 5, 12, 24, 48, 110 and 230 V
  • Large flow capacity and low residual voltage, with no leakage current to ground
  • Series or parallel connection
  • Built-in double lightning protection technology
  • Branded lightning protection components
  • Universal mounting on 32 mm G-rail or 35 mm U-rail (35 mm standard DIN rail)
  • 25 ns response time and IP20 protection
  • Enhanced flame-retardant reinforced nylon housing (UL 94V-0)

Models

  • LP-COM/A-5: Ue 5 V, Uc 8 V
  • LP-COM/A-12: Ue 12 V, Uc 18 V
  • LP-COM/A-24: Ue 24 V, Uc 36 V
  • LP-COM/A-48: Ue 48 V, Uc 60 V
  • LP-COM/A-110: Ue 110 V, Uc 150 V
  • LP-COM/A-230: Ue 230 V, Uc 320 V

How it works

  • Series connection: for power systems with a rated load current not above 10 A
  • Parallel connection: wired across the line with a PE connection

Applications

  • AC/DC power supply systems
  • Computer systems
  • Modems
  • Signal control equipment
