RN 500 v.1.0/VI
RN 12V/5A DC voltage reducer
CODE:
NAME:
DESCRIPTION
The RN 12V/5A (RN500) is intended for lowering and stabilising DC voltage within the range of 12÷14V into the
value of 12V (adjustment 11V÷Uin DC). In the case when the output voltage drops below the preset output value, the
transistor opens and the reducer conducts without any loss (voltage drop ΔU<1%). That enables full use of energy
accumulated in the PSU's battery during batter-assisted operation.
The RN500 voltage reducer along with a typical buffer PSU is intended for supplying devices that require voltage
of 10V÷12 V DC. It is particularly dedicated for CCTV systems (cameras, IR illuminators), KD access control systems and
others which feature devices supplied with voltage of 12V DC (-10%/+5%) and cannot by powered directly from the 13,8V
DC output of a buffer PSU.
