Key benefits - Provides adjustable high voltage DC output (110-2600 V) and adjustable current (0.25 to 3.4 mA) for precise component testing. - Simple control: turn the voltage knob clockwise to increase voltage, counterclockwise to decrease. - Clear testing guidance: for MOS devices, transistors and Zener diodes set current to the minimum 0.25 mA; for LED backlight panels set current to the maximum 3.4 mA. - Compact and portable: small footprint makes it easy to carry in a tool bag for daily use. What it does and how it helps - Delivers stable high-voltage DC for evaluating a range of electronic components and modules. - Versatile for both lab and field work, enabling quick checks without heavy equipment. 2-3 practical use scenarios - Test MOS devices, transistors and Zener diodes in a bench setup with controlled current. - Evaluate LED backlight panels by applying the recommended high current at HV levels. - Carry in a tool bag for on-site component testing and troubleshooting of high-voltage circuits.
