Product name: Current / voltage adjustable switching power supply double digital display 0-80V 0-6A 480W

With intelligent temperature-controlled cooling fan (ultra-quiet)

When the temperature reaches a certain point the fan automatically runs

When the temperature does not need to be dissipated, the fan automatically stops.

Wide range of uses: mainly used for a variety of battery charging, DC equipment, DC motor speed control, LED dimming, chemical electrolytic plating speed control, scientific research testing, student experiments, etc.

Special Note: If you use motors, fans and other inductive loads, please pay attention to the motor maximum starting current parameters, this parameter must not be higher than the maximum use of the power supply current, otherwise it may lead to power damage, you should choose a higher current power supply, or to the motor equipped with soft start protection circuit to absorb the inrush current.

(Power formula) voltage X current = power

For example: connected to 12V10A equipment, the power is 120W, connected to 36V10A equipment, the power is 360W

Current limiting output current range: for example: (0-40A) (0-20A) (0-15A) (0-10A) (0-8A) (0-6A) (0-4A) (0-2.2A) continuously adjustable.

Ripple voltage; no more than 100mV

Regulated equivalent internal resistance: no greater than 0.O5Ω

With short-circuit current limit protection, automatic recovery function

Adjust the current limit operation method.

1, in the case of power failure operation, the lower left corner of the small pull switch pulled to the far left to adjust the current gear.

2, the (special current adjustment insert) pulled out to the wiring port of the second and third port, with a screwdriver to loosen the port screws, connected to tighten with a screwdriver, (at this time access to AC AC), connected to the digital display meter after the voltage display 0.00V, the current display the current current parameters, the power supply at this time will emit a small squeaky current sound.

3, in the right (adjust the current knob) can be adjusted to the desired current limit parameters, and digital display table synchronization display current parameters, such as: 0-21A/0-11A/0-6.5A and other adjustable throughout.

4, the (special current adjustment insert) remove, insert back into the original insert card holder, remove the digital display table shows the voltage of 0.90V or so, the current 0.00A

5, the lower left corner of the pull switch to the right to "open (use)" gear.

6, the power supply is now in the parameter value of the current limit just now, the power supply regardless of the adjustment to a few V (digital display meter real-time display output voltage), the current remains unchanged, the use of the current reaches 95% of the current limit parameters will begin to buck, the start of overload protection

7, at this time, the digital display table shows the current parameters of the equipment load current value, real-time monitoring of the load current.

Note that the use of current-limiting operation after the right side of the power supply (adjust the current knob) do not rotate, rotate the current-limiting parameters with the knob rotate and change.

If there is no need to limit the current, when using general load equipment, without the above operation, pull the lower left corner of the pull switch to the "open (use)" position, turn the (adjust the current knob) clockwise to the top, the current at this time is the rated current limit.

Intelligent equipment / PLC using DC0-5V voltage / current adjustment method: 1.

1, intelligent PLC control voltage connection first remove the product shell, the voltage adjustment potentiometer black wire connected to the DC0-5V positive, the voltage adjustment potentiometer red wire connected to the DC0-5V negative.

2, intelligent PLC control current connection first remove the product shell, the black wire of the current adjustment potentiometer connected to DC0-5V positive, the red wire of the current adjustment potentiometer connected to DC0-5V negative.
