9-50V 2000W motor regulator with 40A shell DC brush motor regulator dimming and temperature regulation module IMDN12 type DC regulator. The regulator is a universal DC voltage regulator 9-50V. Using imported FET/Imported special speed control driver IC/PCB is 2oz 70 micron thickened copper sheet, and the high current balanced PCB layout makes the PWM waveform of perfect and more efficient output. The IMDN12-40A DC regulator is positioned as an entry-level industrial regulator with the characteristics of small size, wide voltage, high current, low temperature rise, high reliability and low price. Technical indicators: (1) Operating voltage: wide operating voltage range DC 9V-50V (2) Control power: 0.01-2000W (the maximum instantaneous current is 40A, and the long-term operating current should be controlled within 20A). Different operating voltages correspond to different control powers as follows; When the working voltage is 12V, 12V x 40A = 480W When the working voltage is 24V, 24Vx40A = 960W When the working voltage is 36V, 36Vx40A = 1440W When the working voltage is 40V, 40Vx40A = 1600W When the working voltage is 50V, 50Vx40A = 2000W (3) Quiescent current: 0.025A (when the working voltage is between DC10V and DC50V, the quiescent current will not exceed 25mA) (4) PWM duty cycle : 5% to 100% (5) PWM frequency: 12khz (6) Operating temperature: -20 -- 40 (ambient temperature -20 degrees below zero to 40 degrees above zero) This regulator is industrial grade and can work stably in sub-zero environment, generally a commercial grade regulator. not possible to work stably below zero. PCB dimensions: length 90mm, width 51mm, height about 30mm (excluding potentiometer adjustment part) illustrate: 1. When shipping, the potentiometer is removed and placed in the case, in order to prevent the product from being damaged. damaged during transportation. 2. When wiring, pay attention that the positive and negative poles of the power supply should not be reversed. Reverse connection is equivalent to a short circuit, and the current is very large, which will instantly burn the regulator. Follow the instructions next to the connection terminals to wire. 3. The governor is a DC governor and the power supply should be DC power supply between 9-50V. The main purpose: 1. Speed regulation of various general-purpose DC brushed motors 2. Regulation of the speed of various types of automobile engines (speed regulation of automobile cooling fans, speed regulation of automobile fans, speed regulation of automobile windshield wiper motors, speed regulation of automobile air conditioning fans) 3 .Production line conveyor belt speed regulation, pipeline exhaust fan speed regulation, treadmill speed regulation, parallel speed regulation of multiple computer fans and speed regulation. speed of electronic fans. 4. Various types of DC bulb dimming, various types of DC heating temperature adjustment.
