JavaLaurence Geschrieben February 16, 2013 at 19:40 Share Geschrieben February 16, 2013 at 19:40 My stack is powered by a Step-Down Bricklet, and brickv indicates that Stack Voltage is 9.5V and Stack Current is 160mA. School physics taught me that Watts = Volts x Amperes. Although a figure of 9.5V is given for "Stack Voltage", I'm assuming that actually the stack is run on 5V, not 9.5V. So does this mean that my stack only consumes 0.8 Watt? Seems like peanuts.. or is my math & physics way off ? Maybe it would be cool to let Brickv display stack power consumption too...

batti Geschrieben February 17, 2013 at 14:45 Share Geschrieben February 17, 2013 at 14:45 The voltage you supply the step down powersupply with is meant with stack voltage. This voltage is transfered through the stack to power driver bricks. The current measurement is not very accurate below currents of 200mA so there might be a tolerance.

JavaLaurence Geschrieben February 18, 2013 at 04:23 Autor Share Geschrieben February 18, 2013 at 04:23 Thanks. My stack currently consists of Step-Down, Master, Wifi Extension, Distance IR, Dual Relay and Humidity. Is the 0.8 Watt figure possible for this configuration? As a software person, I'm not used to dealing with electrical units like this.. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
