    1

    DC Power Supply

    1. Input voltage: 220 V/110V,

    2. Constant Voltage and Current, Continuously Adjusted

    3. Specialized designed for laboratory, school and production lin

    1

    Side Cooling Design

    The side vents correspond to the rear fans to convect the air, so there is no effect of the use and lifetime of this power supply due to excessive temperature during working.

    Auto Conversion of ''A'' and ''mA'' though The Movement of Decimal Point

    Dr.meter PS-305DM

    power supply is a kind of continuously adjustable linear DC voltage regulator power supply with high stability, high reliability and low noise. Its output voltage and current can be continuously adjusted. Also it can be both as constant voltage and constant current dc power supply. Its constant voltage and current can be auto-conversion. This low cost and universal power supply can be used in many different areas, from production lines to school use.

    Feature:

    1. Single output, single phase

    2. 110V/220 +10% input voltage, dual-input voltage.

    3. Output constant current adjustable

    4. Output constant voltage adjustable

    5. 3LED voltage and current display

    6. mA and A converted display which controlled by a button.

    7. Constant voltage and current operation model. C.V and C.C convert automatically

    8. Current limitation protection

    9. Good quality, cost-effective
