DDC420 4 Channel PWM Signal Amplifier

The DDC420 4-channel PWM signal amplifier is designed to amplify the output current of the regulator. Maximum current 20A voltage up to 30V per channel.

The DDC420 4-channel PWM signal current amplifier for RGBW dimmers is designed to amplify the output current of the dimmer.

The modules have the following features:

- The module has 4 independent channels;

- The module has powerful MOSFET transistors and gate drivers controlled by logical levels;

- Maximum load: voltage up to 30V; current up to 20A DC;

- Possible parallel connection of several channels to increase the current up to 80A;

- It can be used as a solid-state DC relay;

- Has a built-in switching stabilizer of power from the incoming voltage 12-25V;

- Powering of the module (12-25V) and the lamps (1-25V) may be different from different sources. But a common negative wire should be one.

- The switching frequency can be in the range from 100 Hz to 1 kHz;

- The module can work together with PWM controllers of any manufacturers and any interfaces;

- Installation in an electric board on a DIN rail, modules 2 DIN wide.
