QJE PS30100 Switching Mode Power Supply

Product Information

The PS30100 power supply is a digital switch type power supply that can output 3000 watts for a long time DC power supply. It is manufactured by Jiuyuan Electronics and is known for its high efficiency, small size, light weight, large screen with high brightness LED display, and intelligent fan. The power supply has various selection levels and is cheap and easy to use, making it a shining star in the power market. It comes in four models: PS30100, PS6050, PS8040, and PS10030. The input voltage is AC220V 50Hz, and The output voltage ranges from 0-30VDC to 0-100VDC depending on the model. The maximum output current ranges from Max100A Rated100A to Max30A Rated30A depending on the model. The power supply has a ripple of 300mVp-p and comes with current limiting protection and over temperature protection.

Product Usage Instructions

1. Use reliable output connection line when using the power supply.
2. Keep the power supply away from heat sources as far as possible and ensure that the environment is dry and the fan vent is clean.
3. Do not use the power supply outdoors.
4. If the power supply fails, do not disassemble it without permission to avoid high voltage electric shock accidents.
5. When using the power supply as a constant current source, turn the voltage adjusting knob (7) to the right to adjust the current (6) to the required current. The current C.C indicator light is on when the current output is constant. If the constant voltage C.V indicator light is on, adjust the load to make the machine return to constant current state.
6. The usage environment for the power supply should be between 0-+40 C relative humidity.

INSTRUCTION

1. When the machine is used as a constant voltage source, turn the current potentiometer (6) clockwise to Maximum, adjust the voltage knob (7) to the required voltage value, the stabilized voltage C. V indicator light is on, and the pressure knob (7) is a precise multi turn potentiometer, which is convenient to obtain the accurate voltage value, and the load will be positive Terminal output positive terminal (2), load negative terminal output negative terminal (3), (4) shows Output voltage value, (5) shows the output current value, if the current display reaches the rated value And the C.C indicator light of the side steady current is on, indicating overload or short circuit at this time, and the negative should be adjusted Load, make the machine return to constant voltage state.
2. When the machine is used as a constant current source, turn the voltage adjusting knob (7) to the right time To adjust the current (6) to the current required, The current C.C indicator light is on when the current output is constant. If the constant voltage C.V indicator light is on, it can be adjusted Complete the load to make the machine return to constant current state.

Attention

1. Reliable output connection line must be used
2. Keep away from heat source as far as possible, keep the environment dry and fan vent clean
3. No outdoor use
4. When the machine fails, please do not disassemble it without permission to avoid high voltage electric shock accident
