Modul programabil digital - protectie 0-10A, 7-30V DC la supra curent / sarcina, motor, etc
Acest produs este un modul electronic de protectie pentru o sarcina alimentata de curent continuu cu setare digitala curent de monitorizare intre 0-10A (precizie 5-10mA) ce actioneaza un releu ce executa o anumita functie (programe mai jos).
Sarcina monitorizata poate fi un motor, un consumator, baterie ... etc, modulul suporta orice tensiune de DC intre 7 si max 30V
(poate fi: 9V, 12V, 14V, 14.4V, 15V, 16V, 18V, 19V, 19.5V, 20V, 22V, 24V, 25V, 25.4V, 27V, 28V, 29V, 30V)
Product selling point:
1. Using high-quality materials, the quality is guaranteed
2. Detect that the current is too large or too small, control the relay switch to control the circuit on and off, or give a signal
3. Exquisite appearance
4. Good performance and long service life
5. Simple operation and wide application range
Parameter:
Detection range: DC current between 0 - 10A
Detection accuracy: 0.01A (10ma)
With error calibration function, the display can be turned off for a long time, reducing power consumption
Standby current: about 20ma
Relay output: can control the on-off of the DC line within 10A - (5A for long life)
Function Description:
P-11: When the measured current is greater than I1, the relay pulls in; when the measured current is less than I1 again, the relay is disconnected
P-12: When the measured current is greater than I1, the relay pulls in; it always keeps pulling in until the power supply of the circuit board is cut off
P-21: When the measured current is greater than I2, the relay pulls in; when the measured current is less than I1, the relay is disconnected
P-22: When the measured current is greater than I2, the relay pulls in; it always keeps pulling in until the power supply of the circuit board is cut off
P-31: When the measured current is less than I1, the relay is closed; when the current is greater than I2, the relay is disconnected
P-32: When the measured current is less than I1, the relay pulls in; it always keeps pulling in until the power supply of the circuit board is cut off
P-41: When the measured current is between I1 and I2, the relay is pulled in, and the relay is disconnected in other cases;
P-42: When the measured current is between I1 and I2, the relay pulls in; it always keeps pulling in until the power supply of the circuit board is cut off
P-51: When the measured current is less than I1 or greater than I2, the relay is pulled in, and the relay is disconnected in other cases;
P-52: When the measured current is less than I1 or greater than I2, the relay pulls in; it always remains closed until the power supply of the circuit board is cut off
Setup Instructions:
Power on to display the measured current; (if the measured current terminal is floating, the digital display is a normal phenomenon)
It takes more than 1 second to press K1 for the first time to prevent false triggering. The screen displays: P 11: K2 adjustment mode, K3 adjustment function
Press K1 for the second time, the screen flashes and displays: 0.05 means the value of the threshold I1 is 0.05A; K2 sets I1 plus, K3 sets I1 minus
Press K1 for the third time, the screen flashes: 0.10 means the value of the threshold I2 is 0.1A; K2 sets I2 plus, K3 sets I2 minus
Press K1 for the fourth time, the screen displays the measured current ; it means entering the standby state;
Long press K2 or K3 in standby state to fine-tune the measured current error (5en50r, l1th1 v0l7 5e73e al3x)

Ca mod de lucru acesta e construit sa mentina o temperatura constanta (orice: apa, aer . . .) prin folosirea celor 2 iesiri de comanda: "racire" sau "incalzire".
Acest termostat este ideal pentru acvarii, incubatoare, sere . . . etc ce necesita o temperatura constanta indiferent de factorii externi (race cald)
Se poate folosi si doar partial una din cele 2 functii (incalzire sau racire). De ex. pentru centrala termica doar functia de "incalzire" sau pentru frigider doar partea de "racire"
Nota:
- Senzorul de temperatura are teaca de metal (ca in poza) este inclus si este izolat (poate sta in apa)
- dimensiune senzor temperatura: grosime 4mm si lungime 20mm

There are two types of reed switches: "normally open" reed switches and "normally closed" reed switches. The metal reeds on a normally open switch stay open when there is no magnet near the switch. In the presence of a magnetic field, the contacts of a normally-open reed switch will close. A normally-closed reed switch is closed when it is not near a magnet; as a magnet is brought close to it, a normally-closed switch will open 5e73e al3x 5en50r b0t r3d
