Features:_x000D_ _x000D_ This module can convert 0-5V or 0-10V analog input voltage into 0-100% PWM signal. _x000D_ PWM signal frequency range is 2KHZ-20KHZ, maximum is 20KHZ, default minimum is 2KHZ. _x000D_ Default function is converting 0-10V into 0-100% 2KHZ PWM signal; output frequency can be set by adjusting potentiometer as needed. _x000D_ PWM signal and voltage can be direct ratio(positive phase output) or inverse ratio (negative phase output). _x000D_ There are two kinds of PWM signal, PNP-PWM output and NPN-PWM output;the PNP-PWM output is only 5V level, NPN-PWM output is 5V and 24V level. _x000D_ NPN-PWM signal output supports common-cathode connection and common-anode connection, 5V and 24V two levels. When output 24V level, it need 24V power supply. _x000D_ For PNP-PWM output, the level can only be 5V. Can only use common-cathode connection, and connect to MCU, etc. _x000D_ Output PWM signal frequency is adjustable within 2KHZ-20KHZ; there are total 11 positions, respectively corresponding to 2KHZ, 4KHZ, 6KHZ, 8KHZ maximum 20KHZ, default frequency is 2KHZ. _x000D_ Used for PWM motor speed control interface circuit, instrumentation AD interface conversion, and other applications that need convert voltage to PWM signal. _x000D_ _x000D_ _x000D_ Specifications: _x000D_ Type: Voltage to PWM signal module_x000D_ _x000D_ Model: V-PWM _x000D_ Input Power Supply Voltage: 7-30V (recommend 15-30V DC) _x000D_ Input Power Supply Current: >200mA _x000D_ Size: Approx. 45 x 47 x 18mm/1.8 x 1.9 x 0.7in_x000D_ Weight: 20g(approx.)_x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1 x Converter Module _x000D_ _x000D_ _x000D_ Note:_x000D_ Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
