Termostat digital controler temperatura, -50C la 110C - model MH1210
Curent continuu DC !
- MH1210 - 12V (versiunea de 12V-DC)
- MH1210 - 24V (versiunea de 24V-DC )
- MH1210 - 14-90V (versiunea cu plaja de la 14V pana la 90V-DC)
Curent alternativ AC !
- MH1210 - 12-60V (versiunea cu plaja de la 12V pana la 60V-AC)
- MH1210 - 230V (versiunea de 230V-AC)
va rog sa specificati modelul cerut
Atentie: Nu se ofera garantie pentru versiunea de 230V daca se monteaza in sisteme trifazice. Am avut surpriza in lipsa nulului ca tensiunea sa depaseasca 245V rezultand in defectarea aparatului. Deci mare atentie !!!
Acest termostat are doua functii de control temperatura: incalzire sau racire, acest lucru se seteaza din meniu. Aceste functii nu merg niciodata in acelasi timp, ori controleaza incalzire (centrala, aeroterma . . . etc) ori racire (frigider, combina . . . etc)
Daca doriti un termostat care controleaza in acelasi timp ambele moduri racire si incalzire (acvariu, clocitoare) vedeti in anunturile mele termostatul STC1000 (stc 1000)
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
- temperatura reglabila -50C la 110C
- Are o singura iesire de comanda 1 x 10A (max) 250 V
- Termostatul arata ca in poza si este nou
- Atentie pentru a comuta electric sarcini mai mari de 10A peste capacitatea Termostatului (Aer conditionat, radiatoare, boiler, pompe de putere ... ) folositi circuite de comanda de puteri mai mari corect dimensionate, comandate de catre termostat (folosirea iesirii de 10A 250 AC)

PD2.0/PD3.1 (PPS) output protocol
Alte observatii:
In primul rand tensiunea de iesire si curent sint controlate prin protocol QC3.0 de catre telefon (tableta etc) si trage atat curent la o anumita tensiune cat doreste dispozitivul nu cat poate maxim aceasta sursa.
Acest modul este o sursa step-down comandata de catre dispozitivul (telefon, tableta . . . ) pus pe USB cu protocol de comunicatie Fast Charging QC4.0, QC3.0, QC2.0 etc pentru incarcare rapida.
La iesire in functie de modul selectat fast charging poate ajunge la max 65W (20V cu 3.25A)
Tensiunea setata implicit (default) de iesire pe USB este de 5V si suporta la intrare o tensiune intre 5V-32V max, adica suporta si auto 12V, 24V
Fiind o sursa step-down, adica doar coboara tensiunea, functia de Fast Charging nu va functiona daca la intrare sa zicem intra 5V, nu poate da 9-12V-20V
De ex se introduce 9V, va functiona Fast Charging intre 5-9V out.
Pentru a asigura o putere maxima utilizata pentru functia fast charging, este necesar ca tensiune de intrare sa fie intre 12V si max 32V. al3x 5y5sa 2s0 d0w7

Description:
This is essentially a ramped up version of our Ardumoto motor driver shield.
For this monster shield we've replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers.
We've also beefed up the support circuitry so this board is capable of driving a pair of high-current motors!
The VIN and motor out are pitched for our 5mm screw terminals (not included), making it easy to connect larger gauge wires.
Note:
When using this board in extreme high-demand applications it may be necessary to improve thermal performance with a heat-sink or fan and to solder the wires directly to the board instead of using a screw terminal (in addition to the myriad other complications present in a high-current system) However,when using the board at currents up to 6A the chips will barely become noticeably warm. d51v al3x r3d
Features:
Power supply: Max 16V
Maximum current rating: 30 A
Practical Continuous Current: 14 A

ATENTIE !
Doar in cazul in care driverul este folosit pentru control motoare curentul maxim suportat este de cel putin 2 ori curentul nominal specificat pe motor.
Adica acest driver suporta motoare ce au curent nominal de max 15A !!! pentru ca trebuie luat in calcul si pornirea lui in sarcina maxima (au fost cazuri).
Daca nu se respecta acest lucru nu ofer garantie !!!

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)
