PULS SLV20.200 Buffer Module

Introduction

The buffer unit is a supplementary device for regulated DC 24V power supplies. It buffers load currents during typical mains faults and switching events or load peaks.

Working principle

In times when the power supply provides sufficient voltage, the buffer unit stores energy in integrated electrolytic capacitors. In case of a mains voltage fault, this energy is released again in a regulated process.

Bridges mains faults without interruption

Statistics show that 80 percent of all main faults last less than 0.2s. These main faults are completely bridged by the buffer unit and will have no influence on the DC power (startup-delay of power supply used might be taken under consideration. This increases the reliability of the system as a whole. 

Extended hold-up time

Once the main power fails or is switched off, the buffer unit will continue to provide the load current for a defined period of time. Process data can be saved and processes can be terminated before the DC power switches off. Controlled restarts are subsequently possible.

Easy to handle, expandable, and maintenance-free

The buffer unit does not require any control wiring. It can be added parallel to the load circuit at any given point. Any given number of buffer units can be switched parallel to increase the output capacity or the hold-up time. The dual terminals allow for easy wiring. In addition, there is a housing connection.
