DGC2007 Daewoo speed control board Environment: Operating temperature range -40 ℃ ~ 85 ℃ Operating humidity range 95% maximum storage temperature -55 ℃ ~ 92 ℃ shaking 20-100HZ 500mm / Sec Input Power: 12V and 24V DC supply voltage battery system ground negative polarity power consumption 40mA continuous current minimum actuator 1A; maximum 4.5A (3062322 maximum current can reach 8A) speed sensor signal 2 ~ 120V RMS ESC1000B basket speed control speed control board from the two areas to illustrate the principle: Fan pump saving principle is to use speed control or throttle control instead Windshield wind flow, which is an effective way of saving. Windshield panels with rated air flow control Q1 = 100% output, the shaft power is proportional to N1 and area AH1 OQ1, if the wind halved Q2 = 50% output, the shaft power is proportional to N2 and BH2 OQ2 area, it is more than N1 reduce much governor US59002, this is because of the need to overcome the windshield board pressure due to increased resistance. If the same amount of wind speed control output by half, the number of revolutions dropped by n1 n2 governor ESD5111, parameter scaling law drawn by the fan characteristic curve when n2, C point for the new mining point governor 3,044,196, which When the shaft power is proportional to N2 and area CH3OQ2, in the same amount of wind Q2 conditions are met, a lot lower axis function, saving power consumption is proportional to the area of ??△ N and BH2H3C seen saving effect is very significant.
