​Basic introduction of LRS single-output power supply

A single-output power transformer is a power transformer with one output voltage. Nowadays, LRS single-output power supplies are everywhere in our lives. However, we may not be very familiar with it. The following will introduce you to the basic information of the LRS single output power supply.

Working Principle

LRS single-output power supply consists of a rectifier, filter circuit, auxiliary power supply circuit and digital display circuit. When the output voltage changes due to the power supply voltage or load current changes, the signal changes through the regulator sampling circuit and the reference voltage is compared, the error signal obtained by the comparison amplifier after amplification, the amplifier circuit control adjusting tube to adjust the output voltage to a given value. Because the comparison amplifier consists of integrated operational amplifiers and has a very high gain, small voltage changes at the output can also be adjusted to achieve a high stable output.

Power Supply Characteristics

LRS single-output power supplies are designed for laboratory, school, and production line needs. The output voltage is adjusted by coarse and fine adjustment potentiometers and can be continuously adjusted from 0 to the rated voltage range in the same gear. The load current is also adjusted from 0 to the rated current range with coarse and fine adjustment potentiometers to obtain any value. Both output values can be accurately read from the voltmeter and ammeter. The excellent stability and ripple are very much in line with modern circuit design requirements. LRS single-output power supply can be used for constant voltage or constant current sources. The operating characteristics of this series of power supplies are in the form of constant voltage/constant current automatic crossover; that is, when the output current reaches a predetermined value, the voltage stability can be automatically charged to the current stability in the power supply behavior.

Preparation

LRS single-output power supply should operate in the specified surrounding environment, its heat dissipation ventilation holes and the wall should be not less than 50cm distance. Power input, output switch placed in the OFF position. To avoid vandalism, do not open the top cover or front and rear panels during use. In long-term use, please place the instrument in a well-ventilated environment,do not place the instrument in an ambient temperature greater than 40C. Avoid placing other instruments or flammable objects on the machine. Do not short-circuit the positive and negative terminals of the front panel output continuously and instantaneously. When using this machine, to ensure the safety of the user and the safety of the surrounding equipment, be sure to connect the output and input terminals to the ground. If there is any abnormality in the instrument, please send it to our professional technical maintenance personnel.
