VA7530S 120V 300A Voltage Current Meter Coulometer Capacity Power Meter with 1.8" Color Screen

VA7530S 120V 300A Voltage Current Meter Coulometer Capacity Power Meter with 1.8" Color Screen

Description:
As a multifunctional instrument, it can display voltage, current, power, capacity, energy, running time and other physical parameters in real time. Through the reserved relay interface, it can realize over-power, over-voltage, under-voltage, over-current and over-temperature protection. Furthermore, it uses a 1.8" color screen to display data in a more comprehensive and clearer way. It is easy to observe.

It can be used to monitor output voltage and current, as well as battery charging and discharge.

Features:
1. Two-way current detection. It is very convenient for users who test charging and discharging to detect bidirectional current without changing the wiring direction
2. Power-off memory function. It can memorize the ampere hour (AH) before the power failure, which is convenient for observation and measurement
3. By using one key to fill up or clear the ampere-hour (AH) value without affecting the direct charge or discharge measurement
4. It can display voltage, current, ampere hour, watt hour, time and power at the same time
5. With output shutdown function key. Output can be turned on or off
6. With over-voltage, over-current, overpower, under-voltage protection and temperature control functions
7. Online calibration is convenient for customers to correct errors in time
8. LCD screen can be automatically turned off and on, reducing the power consumption of the product
9. Switchable voltage and current waveform display function. It is convenient for users to observe the change curves of voltage and current more intuitively
10. The relay port can be switched to the buzzer port to realize sound alarm
11. The under-voltage capacity can be automatically cleared. It can automatically fill up the over-voltage capacity to facilitate long-term use by customers; automatically correct errors
