​How should I use the LRS single-output power supply?

The safe use of the LRS single-output power supply is very important to each of us. If you are not careful, you can make a big mistake and endanger your own life and the lives of others. The following section describes how to use the LRS single-output power supply safely.

Precautions before use

AC power input range should be in the supply voltage between 220V earth 10% 50/60Hz. To avoid electric shock, the grounding protection conductor of the power cord must be connected to the earth. In addition, the heat sink on the back of the LRS single-output power supply is a heat generator. To ensure the life and safety of the instrument, the instrument must be placed in a well-ventilated area to facilitate heat dissipation. To avoid damage to the instrument, do not use this power supply in an environment where the ambient temperature exceeds 40C.When starting or shutting down the power supply, the voltage at the output must not exceed the default value to prevent the OVERSHOOT phenomenon.

Setting the current limit point

First, determine the maximum safety current value needed to supply. A test wire is then used to temporarily short-circuit the positive and negative terminals of the output. Turn the VOLTAGE control knob from zero until the C.C. light is on. Adjust the CURRENT control button to the desired limiting CURRENT and read the CURRENT value from the ammeter. At this point, the current limiting point (overload protection) has been set, do not rotate the current control knob. Then eliminate the output terminal and negative short circuit, connected to the constant voltage source operation. To ensure the life and safety of the instrument, the instrument must be placed in a well-ventilated place to facilitate heat dissipation. When turning on or off the power supply, the output voltage must not exceed the default value to prevent OVERSHOOT.

Maintenance and Cleaning

If the fuses of the LRS single-output power supply are blown, the CV and CC lights will not work and the instrument will not operate. We need to find out the cause of the fuse damage and correct it, then replace the fuse with the correct value and type. To ensure effective fire protection measures are limited to the replacement of a 250V fuse of a specific style and rating.

The instrument can be wiped with a soft cloth moistened with mild detergent and water. But do not spray detergent directly on the machine to prevent leakage into the machine and damage the machine. Do not use hydrocarbons or chlorides, or similar solvents, and do not use abrasive cleaners.

At present, the production technology of LRS single-output power supply has been developed and matured, and gradually tends to be in line with international standards. Zhejiang Ximeng Electronic Technology Co., Ltd. was established in China in 2008. Ximeng's professional team has extensive experience in handling OEM/ODM power supplies and sensor products. Therefore, our company's LRS single-output power supply would be the ideal choice.
