DC Voltmeter Ampere meter Battery Capacity Tester Programmable Meter Controller 0-200V 0-300A Volt Amp Power Ah Auto Shut Down

The unit is designed to monitor performance most kind of battery systems, it continuously monitors voltage, discharge current, number of power, consumed amp hours, these information leads to more efficient use of the battery, which can enhance battery life and reduce the risk of failure. Combines many functions in one, Dual display. *Voltage (V), Power (W), Current (A), Ampere-hour (Ah), Working Hours (H). Equipped with programmable alarm, to run a generator when needed or to turn off devices when the reading reaches a set threshold (relay required). An alarm is acknowledged when a button is pressed. On most of the DCM9040’s readings an alarm can be triggered when the value reaches a set threshold. *[OVP] Over Voltage protection *[LOP] Low Voltage protection *[OCP] Over Current protection *[OAH] Over Charge protection *[OPP] Over Power protection *[OFT] Over Time protection Flexible On-line calibration function, calibrate Voltage and amps reading easily. 4 digits LED, High accuracy Measure currents up to 400 amps, capacity up 999 amp hours. No need isolated power. Technical Specification Power Supply: 5~40V Measuring range: 0-200V/0-1000A (external power), 5-40V/0-1000A (internal power) Display Type: 7 segment 4 digits Red LED Sampling rate: 5 readings per second Accuracy: Volt ± 0.1% + 2byte / Amp ± 0.5% + 3byte Resolution: 0.01V, 0.01A, 0.01W, 0.01Ah, 0.01H Dimensions: 79.0mm x 43.0mm x 25.0mm Package including 1x Combo Meter 1x Expansion board with cable 1x Shunt 1x Installation instruction
