​Operation mode and use of LRS single output power supply

Single group output is different from double group voltage output and multiple group voltage output, it is only one group of voltage output. There are two modes of operation for LRS single-output power supply: constant voltage use and constant power use. The following will introduce you to these two modes of operation.

Constant Voltage Use

Constant Power Use

Constant voltage use

To use the fixed voltage source of LRS single-output power supply, first connect the mains AC220V to the power socket. Set the current limiting point or adjust clockwise to take Current Coarse as the maximum value. Then adjust the Voltage Coarse and Voltage Fine respectively to the Voltage value you need. However, under normal circumstances, it is necessary to first adjust the Voltage Coarse to the nearest required value, and then further adjust the Voltage Fine, so as to adjust the accurate Voltage value you want.

Then load the connection. Connect the negative end of the load to the negative output terminal when the load is less than 2A current. The positive end of the load is connected to the positive output terminal. After startup, MeterA displays the output current value, while MeterV displays the output voltage value. If the ammeter exceeds the rated value and the CC Indicator is on, it indicates overload or short circuit. At this time we should adjust the load, so that the DC power supply to normal.

Constant Power Use

For the fixed power supply of LRS single-output power supply, first adjust Voltage Coarse and Voltage Fine clockwise to the maximum or adjust Voltage Coarse and Voltage Fine counterclockwise to the minimum. At the same time, adjust the Current Fine knob and the Current Coarse counterclockwise to the minimum. Then connect the load as required, and adjust the Voltage Coarse and Voltage Fine clockwise to make the CC Indicator light on. Then adjust Current Fine and Current Coarse clockwise to output Current to the required constant Current value. And the CC Indicator must be on all the time. When the machine is used as a constant voltage source, the current limiting protection point can be arbitrarily set through Current Fine and Current Coarse adjustment knob. Setting method: turn on the power supply, connect the appropriate variable load or short-circuit output end and adjust the load resistance to make the output current equal to the current value of the current limiting protection point. At this point, Current Fine and Current Coarse are adjusted respectively to make the Current Fine indicator in critical state, and the time limit flow protection point is set.

LRS single-output power supplies are widely used in the fields of industrial automation control, military equipment, and scientific research equipment. It is a high-frequency electrical energy conversion device, capable of converting a bit-accurate voltage to the voltage or current required by the user side through different forms of architecture. The high-quality products of Zhejiang Ximeng Electronic Technology Co., Ltd. are very good at this. If you need to buy LRS single-output power supply, please contact us.
