Description

Vynález sa týká zapojenia na reguláciu teploty elektronickým regulátorem za použitia jediného napájacieho zdroje.The invention relates to a circuit for controlling the temperature by an electronic controller using a single power supply.

Dopoeial’ aa k dlhodobej náročnej regulácii teploty elektrotepelných zariadení využívá regulátorov teploty so snímačnom polohy ručičky oscilačného typu, ovládajúce dve relé majáce po dva prepínacie kontakty. Takéto regulátory májá značná hmotnost, objem, sá nákladné a nevhodné pre prostredia s otrasmi a nárazmi. Okrem toho je velmi nákladná miniaturizácia. Tieto nevýhody odstraňujá elektronické regulátory teploty, ich klopný obvod ovládá dve výstupné relé, majúc po jednom přepínačem kontakte. Nevýhodou elektronických regulátorov je ich trojpolohová regulácia v strednom pásme bez akčného zásahu, dovolujúca využit len dva regulačně výkony z jedného napájacieho zdroje. Tieto výkony možno využit iba v dvoch krajných regulečných pásmech, kým středné regulačně pásmo ako najpotrebnejáie nie je využité.In addition, for long-term, demanding temperature control of electrothermal devices, it uses temperature controllers with a sensing position of the oscillating-type pointer, controlling two relays with two changeover contacts. Such controllers are of considerable weight, volume, costly and unsuitable for shocks and impacts. In addition, miniaturization is very costly. These drawbacks are eliminated by electronic temperature controllers, their flip-flop controls two output relays, one contact each. The disadvantage of electronic controllers is their three-position control in the middle band without action, allowing to use only two control powers from one power supply. These powers can only be used in the two extreme control bands, while the middle control band is most needed.
