Product Description

A_S-1WR2 & B_LS-1WR2 series is designed for use in distributed power supply systems and especially suitable in applications such as pure digital circuits, low frequency analogue circuits, relay-driven circuits and data switching circuits, where:

  1. The voltage of the input power supply is relatively stable with a variation of ±10%Vin or less.
  2. An input to output isolation voltage of up to 1500Vdc is necessary.
  3. The requirement for a tight line and load regulation is not as strict.


Note: * The specified maximum capacitive load for positive and negative output is identical.
