## Description

Reduces voltage spikes and interference when switching inductive loads, protecting relays, solenoids, motors, and control circuits. Operates on 5-400V AC or DC, combines an RC network with a varistor for overvoltage limitation, mounts quickly in parallel with the load on terminals or on PCB, compact size 30.5 x 14 mm for easy integration.
The RC absorption module is designed to reduce electrical interference and protect equipment in applications with inductive loads, such as relays, solenoids, or motors.
It integrates a capacitor and a resistor, along with a varistor for surge voltage limitation, helping to prevent discharges and voltage spikes that can affect electronic circuits.
Due to its compatibility with voltages between 5 and 400 V, both in alternating current and direct current, the module offers an efficient and reliable solution for increasing stability and safety in industrial applications or DIY projects.
Specifications:
Module type: RC absorption
Operating voltage: 5-400 V AC/DC
Function: Interference reduction and surge protection
Mounting: Directly on load terminals or on PCB
Dimensions: 30.5 x 14 mm
Usage:
Connect the module in parallel with the inductive load, respecting polarity. During operation, it absorbs voltage spikes and reduces electromagnetic interference generated when switching the load, protecting both the equipment and the associated control circuits.
Do not mount on the power supply without being in parallel with the targeted load.
The module should be mounted as close to the load as possible.
