Description

Equipment like industrial machinery and test instrument contains a lot of high-precision analog signal processing circuitry for sensing. Most of the time, those analog circuitries require positive and negative power lines. In addition, the power lines have to be isolated for reliability to prevent unexpected failure on sensor nodes to spread across the whole system.

Features

  • Designed for evaluation of two types of isolated power supplies.
  • Power Circuit type 1: Input 24V, Output -operationally isolated voltage selectable (±15V, ±12V, or ±5V) by jumper pins
  • Power circuit type 2: Input variable 5~24V, Output operationally isolated power at the same voltage as input (nominal tolerance ±10%)

Typical applications

  • Distributed Power, Multiple Output Supplies, Positive-to-Negative Supplies
  • Medical Instrument and Safety
  • Noise Immunity in Data Acquisition, RS232 and RS485
  • Low Noise Isolated Supplies
