DEMM Engineering & Manufacturing - - ELECTRICAL TECHNOLOGY -

An open board tem­per­a­ture con­troller de­signed with a pro­por­tional in­te­gral con­trol al­go­rithm, to pro­vide the most pre­cise con­trol to ther­mo­elec­tric (Peltier ef­fect) mod­ules, has been re­leased by Oven In­dus­tries.

The H bridge con­trol pro­vides a seam­less tran­si­tion be­tween heat­ing and cool­ing, elim­i­nat­ing dead spots. A red LED for heat and green LED for cool­ing in­di­cate mode.

Pulse width mod­u­la­tion con­trols the power level in the ther­mo­elec­tric mod­ule at a base fre­quency of 900Hz. Power res­o­lu­tion is one of ±255 steps in the load cir­cuit con­trol.

The unit fea­tures solid state H-bridge con­trol, bidi­rec­tional con­trol (seam­less tran­si­tion) and TTL to USB com­mu­ni­ca­tion via op­tional OI-TTL-ca­ble.

Oven In­dus­tries sup­plies cus­tom tem­per­a­ture con­trollers and sen­sors that serve a range of in­dus­tries.
