CG DC Battery Monitor Meter With Shunt

Multifunction DC Battery Monitoring

The CG DC Multifunction Battery Monitor Meter is designed to display key electrical data including voltage, current, power and energy consumption on a clear LCD screen. It is a practical option for cars, RVs, caravans, battery boxes, workshop projects and protected DC electrical setups where accurate battery and load monitoring is required.

Clear LCD Display For Key Electrical Readings

The large LCD screen displays voltage, current, power and energy values together, making it easier to monitor how your DC system is performing at a glance. The backlight can be switched on or off using the front button, with the selected backlight status stored automatically for the next use.

Suitable For Multiple Current Range Options

This meter is available in different measuring configurations, including a 20A version with a built-in shunt and external shunt versions suitable for 50A and 100A setups. The PZEM-031 model supports a 20A measuring range with built-in shunt, while the PZEM-051 version is designed for external shunt use and can be matched with 50A or 100A shunts depending on the selected setup.

Measures Voltage, Current, Power And Energy

The meter supports DC voltage testing from 6.5V to 100V, current display up to the selected shunt range and power readings up to 10kW. It also records energy usage up to 9999kWh, making it useful for tracking battery draw, power consumption and general system load across compatible DC electrical installations.

Voltage Alarm And Power Data Functions

The built-in voltage alarm function can be set to provide over-voltage or low-voltage warning prompts through display flicker and backlight indication. The meter also includes power-down data storage, allowing stored energy data and settings to remain saved when power is disconnected.

Simple Button Control

A single front button controls the backlight, energy reset function, voltage alarm setting and current range selection. For 50A shunt use, the meter range should be set to 50A before operation, as the default setting may be configured for 100A depending on the selected model.

Designed For Protected DC Installations

The unit is suitable for protected indoor or enclosed installations and should not be exposed directly to outdoor conditions. It is well suited for dashboard panels, battery monitoring panels, RV electrical compartments, caravan power systems, DIY 12V and DC setups, and workshop test boards where the rated voltage and current limits are followed.

Wide DC Voltage Compatibility

The meter operates from 6.5V to 100V DC, making it suitable for a wide range of compatible DC battery and power systems. Measurement accuracy is listed at approximately ±1% for voltage, with an accuracy class of 0.5 and an operating temperature range of -40°C to +60°C.

Important Shunt Selection Notes

This meter must be used with the correct shunt for the selected current range. Some options may include only the meter, while others include a matching shunt, so the correct version should be selected before purchase. The wiring order must be followed correctly and the connected load must not exceed the rated voltage or current of the chosen meter and shunt configuration.

Practical For Automotive And DIY Electrical Monitoring

Whether used for a vehicle electrical project, RV power monitoring, caravan battery system, auxiliary battery panel or general DC workshop setup, this LCD meter gives a clear view of system voltage, current draw, power use and accumulated energy consumption in one compact display.
