Product Name: DC ammeter DC0-10A digital ammeter digital ammeter head
Product Type: C27
Color classification:
Product details: Baby Description:
1, the ammeter compact, range DC DC0-10A, after the decimal point two. The need for additional auxiliary power. Wide supply voltage range up to 4.5-28V, can work in 9V, 12V, 24V, etc., without regulation. Power supply has reverse polarity protection, reverse does not burn. Display devices use the bright LED digital display is stunning. Using automatic SMD technology manufacturing, technology skills.
2, the DC ammeter range is DC0-10A,
3, built-in shunt resistor, 10A direct current input (do not hold full-scale input).
4, you must use an external power supply voltage for DC4.5-28V.
5. Special Note: In order to take power from the meter is working measuring circuit, this meter is designed to supply the input common ground, the sampling line (thick) black line is the ground, while the other received a thick line the ammeter input terminal of the amplifier circuit. Therefore, the sampling line (thick line) then the positive is totally unacceptable and must be connected to the appliance after use (ie, negative electrical appliances). Otherwise, it will instantly burn meter, causing no display or display ---. Please be sure to confirm before buyers clearly the two meter thick line must be connected between the two negative! Please refer to the specific connection wiring diagram on the page. We have a prominent position on the page are described in the Want emphasize again, but also because wiring errors caused by burning table, then, the restaurant is not responsible.
6 meter high input impedance, high requirements for power supply ripple, and susceptible to interference. Do not use poor power converter (especially DC / DC switching power supply). Do not close the shunt ammeter and interference sources (such as electric car charger), lead and ammeter shunt between not too long, if you have to grow, then please use shielded cable.
7. Note: This electrical instruments installed by professionals understand the need of electrical and electronic, for installation unclear ordinary consumers buy with caution!
