Wattmetrul este configurabil din meniu unde se alege suntul folosit 50A, 100A, 200A si 300A
Atentie pentru montarea la baterie in sisteme solare (etc) nu se alimenteaza pe cele 2 fire separat decat daca tensiunea bateriei e sub 8V !!! respectati schema din poza (sau manual)
Atat in poza cat si manual aveti desenat "baterie" si "sarcina" pentru montare in sisteme regenerabile (foto, eoliant etc) "bateria" din schema inseamna invertorul (MPPT ... charger .. etc) iar "sarcina" inseamna bateria dumneavoastra (12V, 24V, 48V, 96V ...) Am pus si o schema pentru configuratie sistem solar de exemplu
Acest watmetru se poate monta la ORICE atat timp cat se respeceta specificatiile tehnice cum ar afi: NUMAI tensiune continua (NU alternativ) avand maxim 200V iar curent max in functie de sunt 50-300A
Daca nu se respecta cele de mai sus, nu ofer garantie.
- Wattmetru de curent continuu DC 0-200V (cand este alimentat sub 8V necesita alimentare separata)
- Functii de masurare: tensiune, curent, putere masurata in sarcina cat si energia consumata in unitate de timp (wh)
- se poate seta parametri bateriei si se poate vdea cand e goala sau plina
- modul de conexiune cabluri este afisat in poze (conform pozei de pe spatele aparatului)
- Functie de iluminare pe intuneric (LCD iluminat)
- dimensiune cote (mm) in ultima poza

Modulul vine fara alimentator si fara senzori.
Senzorii pot fi orice, fire, electrozi inox ... etc
Detecteaza nivelul apei prin conductivitatea electrica dintre cele 3 puncte (senzori) porneste umplerea (golirea) si se opreste doar cand s-a umplut (golit)
Face ciclu complet umplere (golire) fara intermitente de alta natura.
Releu comanda max 30A - 220VAC, RECOMAND pentru viata lunga a fi folosit la 50% (15A - 3.5Kw) a nu se folosi la sarcina max de 30A - 7kw chiar daca suporta, speranta de viata este de 1 an ! (valabil la majoritatea releelor cu actionari dese) daca se doreste a comanda sarcini si pompe mari (hidrofor) avand curent mai mare de 15A acest modul va comanda un contactor si acela va comanda sarcinile mari de putere
Atentie functia automatizare de umplere bazin cu apa se poate inversa si poate goli un bazin cu apa (sau alte substante) prin simpla inversare POZITIEI senzorilor, si anume: pozitia senzorului de gol se pune in pozitia senzorului de plin si invers, astfel se inverseaza functia de umplere in bazin in functia de golire bazin. Acest modul este reversibil.
Features:
1: Wide range of applications
2: Easy to operate
3: Small size
4: stable performance
5: Voltage specification optional 12V - DC
Product name: Automatic water level controller
Specifications: 12V - DC
