Operational use
(How to limit the current) Adjust the current?
1,When operating under power outage, turn the small toggle switch in the lower left corner to the current regulation position
2,Pull out the (dedicated current adjustment plug) and connect it to the second and third ports of the wiring port. Use a screwdriver to loosen the port screws, then tighten them with a screwdriver (connected to the power supply at this time). After connecting them, the voltage of the digital display meter shows 0.00V, and the current displays the current parameters. At this time, the power supply will emit a squeaking current sound
3,The (current adjusting knob) on the right can be adjusted to the desired current limiting parameters, and the current parameters can be displayed synchronously with the digital display meter. 0-21A/0-16A/ 0-11A/ 0-6.5A Fully adjustable
4,Remove the (special current regulating insert) and insert it back into the original insert card holder. After removal, the digital display meter shows a voltage of about 0.90V and a current of 0.00A A.
5,Pull the pull switch in the lower left corner to the rightOn (use) gear
6,The current power supply is at the parameter value of current limiting just now. No matter how much V the power supply is adjusted to (the output voltage is displayed in real time by the digital display meter), the current is constant. When the current reaches 95% of the current limiting parameter in use, it will start to step down and start overload protection.
7,At this time, the current parameter displayed on the digital display meter is the current value of the equipment load, and real-time monitoring of the load current
When there is a load device connected, the current value can be directly adjusted in real time. The current value displayed on the digital display is the current value of the load device. If the current adjustment knob is clockwise and exceeds the current value of the device, the current value displayed on the digital display will not be continuously synchronized in real time, and only the current value of the device will be displayed
If there is no need for current limiting, use general equipment without the above operation. Turn the pull-out switch in the lower left corner to the "on (use)" position, and rotate the current regulating knob clockwise to the top. At this time, the current limiting is 21A/16A/11A/6.5A/4A, at this time, the power supply parameter is the output 0-24V21A/0-16A/0-48V11A/0-36V15A/0-80V6.5A/0-120V4A, which is equivalent to a 0-24V20A/0-36V15A/0-48V10A/0-80V6A/0-120V4A switching power supply
Purpose: Mainly used for various battery charging (including various lithium batteries), DC equipment,DC motor stepless speed regulation, LED stepless dimming, chemical electrolytic electroplating speed regulation,Scientific research tests, student experiments,Wait a minuteand a wide range of uses.
Special attention: if motors,  , etc. are used. Inductive load Please pay attention to the starting current parameter of the motor, which should not be higher than the current used by the power supply, otherwise the power supply may be damaged. You should choose a power supply with larger current, or equip the motor with a soft start protection circuit to absorb the impact current.
Power formula) Voltage X Current=Power
For example, if you connect a 12V10A device, the power is 120W, and if you connect a 36V10A device, the power is 360W;
