Operation use

(How to limit current) Regulate current?

1. In the case of power failure, pull the small pull switch in the lower left corner to the current adjustment gear

2. Pull the (special current adjustment plug-in) to the No. 2 and No. 3 ports of the wiring port, loosen the port screw with a screwdriver, tighten it with a screwdriver (connect the listed power supply at this time), and then connect the meter voltage display 0.00V , the current shows the current current parameters. At this time, the power supply will emit a small current.

3. The right side (adjusting current knob) can adjust the required current limiting parameters, and display the current parameters synchronously with the digital display. 0-21A/0-16A/0-11A/0-6.5A full adjustable.

4. Remove (specially adjusted current plug) and reinsert it into the original card socket. After removing the digital display, the voltage is about 0.90V and the current is 0.00A.

5. Pull the pull switch in the lower left corner to the right to open the "on (use)" position.

6. The current power supply is within the current limiting parameter value. The power supply is adjusted to a few V (the digital display displays the output voltage in real time), the current remains unchanged, and the current reaches 95% of the current limiting parameter. Overload protection

7. At this time, the current parameter displayed by the digital display is the current value of the equipment load, and the load current is monitored in real time.

After connecting the load device, the current value can be directly adjusted in real time. The maximum current value is the maximum current value of the load device. If the current adjustment knob clockwise exceeds the maximum current value of the device, the digital current value will not persist. Real-time synchronous digital display, only the maximum current value of the device is displayed.

If current limiting is not required, use a general-purpose device, and do not perform the above operations. Pull the pull switch in the lower left corner to the "on (use)" position, and turn the (current adjustment knob) clockwise to the top. The maximum current limit is 21A. /16A/11A/6.5A/4A, the power supply parameters are output 0-24V21A/0-16A/0-48V11A/0-36V15A/0-80V6.5A/0-120V4A, equivalent to a 0-24V20A /0 -36V15A/0-48V10A/0-80V6A/0-120V4A switching power supply

Uses: Mainly used for various battery charging, DC equipment, DC motor stepless speed regulation, LED stepless dimming, chemical plating speed regulation, scientific research testing, student experiments, etc., widely used.

Special Note: If using an inductive load such as a motor or fan, please pay attention to the maximum starting current parameter of the motor. This parameter must not be higher than the maximum operating current of the power supply. Otherwise, the power supply may be damaged. You should choose a higher current power supply or soften the motor. The protection circuit is activated to absorb the inrush current.

Precaution:

When using the charger, unplug the battery and turn off the input power. If it will not be used for a long time, please store it in a ventilated and dry environment.

For safety, do it within sight while charging. If you need to leave, remove the battery to avoid unpredictable danger.

Do not mix batteries of different types, capacities and manufacturers.

Keep away from flammable items while charging, pay special attention to battery temperature. If the temperature is very high, such as hot, please disconnect the power immediately to stop charging.

Do not drop wires or other conductive objects into the charger. Do it at your own risk.

z Do not charge the battery if it leaks, bulges, falls off, becomes discolored or deformed.

Do not attempt to charge non-rechargeable batteries.

Do not exceed the charging range specified by the battery manufacturer.

Do not modify or disassemble the charger. Open the machine and indicate that you have waived all warranties and technical
