TR24 IP68 Waterproof TFT Color Screen Battery Shunt Monitor for SOC Monitoring

Product Overview

The TR24 is a shunt based battery monitor built for accurate capacity monitoring of battery packs. It measures current through an external shunt and shows voltage, current and remaining capacity on a bright TFT color screen. Because the reading is taken from the shunt instead of relying on voltage alone, the state of charge (SOC) stays stable and does not rise and fall as the pack voltage changes. The monitor supports a wide range of battery types and is rated IP68 waterproof, so it can be installed in damp or exposed positions such as marine and vehicle compartments.

Core Features

• Stable SOC Tracking: Shunt based current measurement keeps the state of charge steady across all supported battery types, avoiding the swings seen on simple voltage only gauges.
• TFT Color Screen: A clear TFT color display presents voltage, current and capacity at the same time, so the battery status is easy to read at a glance.
• IP68 Waterproof: The sealed housing protects the electronics from water and dust, making the unit suitable for engine bays, boats and outdoor cabinets.
• Wide Input Range: Supports 8-100V DC working voltage and 0-500A current measurement through an external shunt.
• Accurate Measurement: Measurement accuracy of +/-1% keeps the reported figures consistent with the actual pack condition.

Product Installation

Step 1: Prepare the Panel Opening
Refer to the product cutout drawing to prepare the mounting opening required on the equipment panel where the battery monitor is to be fitted.

Step 2: Insert the Battery Monitor
From the front of the equipment panel, insert the battery monitor into the prepared opening.

Step 3: Secure the Battery Monitor
At the rear of the product, attach the mounting clips to the battery monitor following the direction indicated in the installation diagram, then tighten the clips firmly so that the monitor is held securely in place, as shown in Figure 1.

Installation Note
Before starting installation, confirm the required panel cutout dimensions against the applicable product installation drawing. Adhere to the installation direction and mounting method specified for the confirmed product configuration.

Actual Product Testing and Inspection

The image above shows an actual electronics testing environment in which battery monitoring products are evaluated with professional test equipment, electrical connections, and measurement instruments.

During product testing, the TR24 battery capacity indicator can be connected to a controlled power and measurement setup to check applicable electrical, display, and functional parameters according to the confirmed product configuration. Testing activities may include power-up verification, TFT color screen operation, voltage and current indication, battery capacity parameter display, and other applicable functional checks.

For the TR24 battery monitor, the applicable inspection requirements are determined based on the confirmed model, the 8–100V operating range, the 0–500A current measurement configuration, shunt configuration, display specifications, and production requirements. Test procedures and inspection items may vary depending on the specific product configuration and customer requirements.

Actual testing and inspection records can be maintained in line with applicable production and quality-control requirements. Supporting technical specifications and inspection documentation can be provided according to the confirmed TR24 configuration.

Applications

• Battery pack capacity monitoring in general purpose battery systems.
• Monitoring the SOC of the battery types within the 8-100V DC range.
• Installations exposed to moisture or dust, where the IP68 rating is required.
• Equipment that needs voltage, current and capacity visible at the same time.

FAQ

Q: Does the SOC reading jump around like a voltage meter?
A: No. The TR24 measures current through an external shunt, so the state of charge reading remains stable and does not rise and fall with voltage.

Q: Which battery types can it monitor?
A: It is designed to monitor the SOC of a wide range of battery types whenever the pack voltage falls within 8-100V DC.

Q: Can it be used outdoors or near water?
A: Yes. With an IP68 waterproof housing, the monitor can be mounted in damp or exposed areas.

Q: Is the display readable in different conditions?
A: The TFT color screen shows voltage, current and capacity together with clear contrast for easy reading.

Q: What is the current measurement range?
A: Current is measured from 0 to 500A through the external shunt.
