300V 1.6A 480W Adjustable DC Power Supply Current limiting Power Transforme New
Descriptions:
Application:
Mainly used for various battery charging, DC equipment, DC motor stepless speed regulation, LED stepless dimming, chemical electroplating speed regulation, scientific research test, student experiment, etc., and a wide range of uses.
Specification:
Model: HJS-480-300
AC Input: 110v/220v±15
DC DC output: 0-300V 0-1.6A
Power: 0-480w
Package Size: about 230*120*60mm
Operation to use :
(How to limit current) to adjust current?
1. Operate in the case of power failure, pull the small pull switch in the lower left corner to the current regulating gear
2. Pull out (dedicated current regulating insert) to the 2nd and 3rd ports of the wiring port, loosen the port screw with a screwdriver, and tighten with a screwdriver (at this time, connect to the listed power), and then connect The voltage of the meter shows 0.00V, and the current shows the current current parameter. At this time, the power supply will emit a small current.
3. On the right side (adjust current knob), you can adjust the desired current limit parameter, and display the current parameter synchronously with the digital display. 0-1.6A can be adjusted in the whole process.
4. Remove the (special adjustment current plug) and insert it back into the original insert card holder. 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 "open (use)" position.
6. The current power supply is in the parameter value of the current limit. The power supply is adjusted to a few V (the digital display shows the output voltage in real time), the current does not change, and the current reaches the current limit of 95% of the current limiting parameter. Overload protection
7. The current parameter displayed by the digital display at this time is the current value of the device load, and the load current is monitored in real time. When the load device is connected, the current value can be adjusted directly 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 last. Real-time synchronized digital display, showing only the maximum current value of the device.
If there is no need for current limiting, use the general equipment, without the above operation, pull the pull switch in the lower left corner to the "open (use)" position, and turn the (current adjustment knob) clockwise to the top. The maximum current limit at this time is 1.6A, at this time the power supply parameter is the output 0-300V1.6A, which is equal to a 0-300V1.6A switching power supply
Special Note:
When using inductive loads such as motors or fans, pay close attention to the motor's maximum starting current rating. This parameter must not exceed the power supply's maximum operating current, as exceeding it may damage the power supply. Either select a power supply with a higher current rating or equip the motor with a soft-start protection circuit to absorb the inrush current.
Power Formula: Voltage × Current = Power
For example: Connecting a 12V 10A device yields 120W power; connecting a 36V 10A device yields 360W power.
