Product Description
The RN250 reducer, in conjunction with a typical buffer PSU, is dedicated to supplying devices that require stabilized voltage of 10V÷12V DC. In particular, it is dedicated to CCTV systems (cameras, IR illuminators), KD access control systems and others where there are devices supplied with 12V DC (-10%/+5%) and cannot be powered directly from the 13.8V DC output of a buffer PSU.
Main features :
- supply voltage max. 14V DC
- power supply output 12V DC/ 2,5A
- output voltage adjustment range 11V÷Uin
- linear voltage stabilization
- lossless conduction below stabilization threshold
- Protections:
- short circuit SCP
- Overload OLP
