Product Details
1、 Overview
The DSP-500 series precision digital display DC stabilized current and stabilized voltage power supply is a high stability DC linear power supply specially designed for the characteristics and special requirements of standard light sources. It has a series of advantages such as high intelligence, convenient use, continuous adjustable output current and voltage, good stability, and high accuracy. It is a new generation of intelligent instruments. The power supply has high-precision current and voltage digital display instruments, especially suitable for high-precision on-site monitoring, and is an ideal power supply for standard light sources. And it has the following characteristics:
1. The instrument adopts encoder for numerical control adjustment, and has three adjustment gears: COARSE (coarse adjustment), MIDDLE (middle note) and FINE (fine adjustment). Compared with the traditional mechanical Potentiometer, it has the advantages of long service life, convenient adjustment and good reliability.
2. The instrument has an alarm function for voltage and current exceeding the upper and lower limits.
3. Adopting high-speed MCU and high-precision D/A, A/D for control and measurement, the instrument has a high degree of intelligence.
4. Two window digital real-time display of current and voltage values, with intuitive readings.
5. Equipped with RS232 or RS485 (optional) communication function, the upper computer can be used for remote operation, control, and reading of corresponding data on the instrument.
6. The output voltage (current) has good stability and high accuracy.
7. The power supply automatically switches between stable current and stable voltage states, and uses corresponding indicator lights to indicate the current state, which has high reliability.
8. The power supply has a remote external sampling function, which can compensate for the voltage drop generated on the wiring, thereby ensuring the accuracy of the voltage at both ends of the load.
9. The relay has a long lifespan and high reliability.
