Watmetru - Coulombmetru DC 300V, 400A, bidirectional cu Bluetooth

Acest watmetru are functia de coulombmetru, se poate masura bidirectional si poate detecta (dupa mai multe cicluri) capacitatea in Ah a bateriei fara sa faceti test de capacitate. Aceasta functie de coulombmetru va ajuta in timp sa vedeti cum evolueaza viata bateriei fara sa o desfaceti si sa o puneti la test, la 1 an , 2 ani, etc. Acest model e cu bluetooth BT.

Recomandare a nu se depasi tensine de 100V, chiar daca suporta, nu inseamna ca e ok, pe termen lung viata lui se micsoreaza daca se foloseste la limita.

Pentru tensiuni mai mre de 100V, este necesar sa fie alimentat separat si doar pe firul galben se poate face masurarea pana la 300V

Function introduction:

1. Measure the percentage of remaining battery power (%) and the number of remaining battery power (AH).
2. Measure the DC positive and negative bidirectional current. Measure the DC voltage.
3. Measure the DC positive and negative power.
4. Measure the cumulative electric energy in positive and negative DC directions.
5. Over voltage alarm function, alarm voltage size parameters can be set by yourself. (With alarm sound and alarm output control CN2)
6. Low voltage alarm function, alarm voltage size parameters can be set by yourself. (With alarm sound and alarm output control CN2)
7. Over current alarm function, alarm current size parameters can be set by yourself. (With alarm sound and alarm output control CN2)
8. Low battery remaining power alarm function, and the power icon will flicker constantly, prompting the user to charge. (With alarm sound and alarm output control CN2)
9. Battery over temperature alarm function, and the alarm temperature can be set automatically. (There is an alarm sound and alarm output control CN1, which can be used to control the battery cooling fan. Note: All control output signals are weak signals of 10MA, and the drive equipment needs to be amplified by the customer's external amplifier circuit for control.)
10. Power failure data saving function.
11. Hall sensor is used for isolated measurement, which is safe and reliable, and the wiring installation is very simple and convenient.
