Description
The DC and Pulse Converter offers various control options, including using a DC voltage or pulse width modulation (PWM). Designed as a replacement for the potentiometer, this module utilizes optocouplers to provide galvanic isolation for the control circuit.
The module supports different voltage ranges for control purposes. When using DC voltage, the control can be achieved within the ranges of 1-5 V/DC, 3-12 V/DC, and 6-24 V/DC. Control can be done using TTL rectangular pulses at 5 V/DC with modulation from 10% to 90% at 1-10 kHz. By adjusting the pulse width, the module allows for regulation and fine-tuning of the controlled power modules.
The primary function of this module is to provide a convenient and flexible means of controlling power control modules. The Module offers an alternative to traditional potentiometer-based control methods, making it suitable for integration with microcomputers or PCs.
The use of optocouplers ensures galvanic isolation of the control circuit. Optocouplers are electronic devices that provide electrical isolation between input and output circuits while allowing the transfer of signals using light. The galvanic isolation provided by the optocouplers ensures the safety and protection of the control circuit and prevents any potential electrical interference or hazards.
The DC and Pulse Converter control inputs accept various voltage levels, allowing compatibility with different control sources. The voltage ranges of 1-5 V/DC, 3-12 V/DC, and 6-24 V/DC cover a wide range of control options, providing flexibility in choosing the suitable control voltage based on the specific requirements of the application.
Furthermore, the module supports control via TTL rectangular pulses at 5 V/DC. This feature allows for precise control using pulse width modulation (PWM) techniques. PWM is a method of encoding information onto a pulsing signal by varying the pulse width. By adjusting the pulse width within the range of 10% to 90%, the module enables precise regulation of the power modules. You can further enhance control options based on specific application needs by adjusting the frequency of the rectangular pulses, ranging from 1 kHz to 10 kHz.
This module offers a versatile solution for controlling power control modules. By connecting it in series, it allows control using either a DC voltage or pulse width modulation. The use of galvanic isolation through optocouplers ensures the safety and protection of the control circuit. With compatibility for various control sources this provides a comprehensive solution for power module control.
