The KWS-DC28 TFT DC Power Tester is a multifunction diagnostic tool designed for evaluating batteries, chargers, power supplies and other DC-powered devices. The integrated 5.5x2.1mm DC barrel plug and jack allow quick inline testing without modifying cables or equipment.

Advanced Analysis for DC Power Systems

Featuring a bright 0.96-inch TFT colour display, the KWS-DC28 provides significantly more information than a basic voltage and current meter. In addition to displaying voltage and current measurements, it can calculate power consumption and provide battery capacity and energy monitoring functions.

Supporting operating voltages from 4V to 30V DC and currents up to 12A, the tester can be used with power adapters, rechargeable battery systems, solar equipment, portable power stations, mini UPS systems and other DC-powered electronics.

Bidirectional current monitoring allows both charging and discharging operation to be evaluated, while memory functions help users analyze equipment performance over time.

Technical Specifications

Selectable Display Modes

The KWS-DC28 features two display modes that can be selected using the push button located on the top of the unit. The default display provides quick access to voltage, current, power, elapsed run time and accumulated capacity measurements. The detailed display provides additional operating information, making it easier to analyze power consumption, battery performance and charger operation during testing.

The ability to switch between display screens allows users to focus on either everyday measurements or more detailed diagnostic information without connecting additional equipment.

Push Button Functions

• Single Press: Switch between the Default Display and Detailed Display screens.
• Double Press: Rotate the display 180 degrees for improved viewing orientation.

The display rotation feature is particularly useful when the tester is connected in different orientations, allowing the screen to remain easy to read regardless of how the unit is positioned within the test setup.

Why Choose the KWS-DC28?

The KWS-DC28 is designed for users who need more than basic voltage and current readings. In addition to measuring voltage and current, it can monitor power consumption, accumulated energy usage and battery capacity, making it a valuable tool for evaluating batteries, chargers, portable power systems and DC-powered equipment.

Compared to basic inline power testers, the KWS-DC28 provides more diagnostic information through its TFT colour display, selectable display modes, display rotation feature and advanced power analysis functions. This additional information helps users evaluate batteries, chargers and DC-powered equipment with greater accuracy.
