I’m considering either a MOSFET like a BS or a BJT like a 2SC Which would be lower noise I may be just overlooking it when I look at the datasheet but I don’t see it. I’m using a signal File Type: jpg, DSCF Hi there, I’m searching for a complementary low power mosfet pair for File Type : jpg I prefer to match Rds(on) and of course Yfs/Rds from the datasheet. #2 is BS and BS which has comparable small capacitance.

The theory is explained pretty well in the datasheet. That said a TEC should have considerable thermal mass so you shouldn’t need to switch that fast.

As per redbeard, i also put my primary dew heater wires behind the corrector, but my insulated dewshield also goes right back over the OTA as far as possible to retain as much dewheater heat as possible in the OTA.

Last edited by Garbz; at Have attached piccies of a unit i made up for fun that could a Have one DewHeater channel controlled via several means including using dewpoint, defined PWM duty cycle or auto temp delta mode.

Also some plastic RCA connectors have exposed parts of the shield. Members who have read this thread: How to measure Current with a Pic I guess I don’t fully understand this concept. Allegro make some really good current sensors which look like a TO style case with built in shunt. Cant think of the part number at the mo but I’ve used in the past and work well up to 60amps. Page 2 of 5. Shouldn’t be too difficult to fit a gate driver circuit in the box.


As all scopes and setups and weather are different so lots of tweaking for optimal results. The humidity sensor is on the inside lid of the small box that sits on the tube, and has holes in the lid to pick up the dew. Originally Posted by redbeard snip.
