Brief Introduction:
A high-efficient yet flexible instrument which can be used to measure the voltage of vehicle batteries. It is especially suitable for vehicle, yacht, electric toy, tool or motorcycle with singular or double set 12V lead acid storage battery.
Advantage over other panel meters by competitors:
- Compared with LCD panel meter, LED panel meter is featured with high contrast and wide viewing angle
- Convenient operation(DO NOT need additional power supply) and simple wiring with only two pieces leads as power positive and negative.
- Self adapted to ambient brightness, not dazzling in night time since the panel meter can automatically adjust its displaying brightness.
- Over 90% components are SMT based, reliable and environment-friendly.
- UL and CE-certified compound AWG22 cables are used, low voltage drop.
- The following figure is the comparision of heat emitted by ME-SP039 (right) and other panel meter (left) by competitors in working status. It clearly shows that the heat emitted by major components of ME-SP039 is comparatively low, which makes it an ideal sel ection for application in harsh environment.
*: Heat is measured by Fluke Ti20 Thermal Imager
Features:
- Large (0.56”/14.2mm) easy-to-read red LED display.
- Wide application range. Can be used to measure the voltage of various vehicle batteries ranging from 8.5-30V DC.
- Successive approximation-based AD conversion, which is fast and accurate.
- High-efficient DC-DC converter, low temp rise, which is far below the temp rise of other competitive products.
