Description
UNI-T UDP3303A / UDP3303C 30V / 3A High Precision 3-Channel Programmable DC Power Supply
Features:
- The UDP3300 Series Programmable DC power supply is a cost-effective program control DC power supply with outstanding performance, reliable output, and a clear interface
- The UDP3303C/A DC power supply has three independent outputs: two of them are adjustable outputs of 30V/3A, the other one is a fixed selectable output of 1.8V/2.5V/3.3V/5V/3A (fine adjustable)
- With the constant voltage (CV) and constant current (CC) modes, short circuit, and overvoltage protection features, the instrument can perfectly meet various test requirements
- Four-digit voltage and current display: voltage resolution 0.01V/current resolution 0.001A, a multi-turn precision potentiometer to set the voltage and current output value.
- Series-parallel mode can provide up to 60V voltage or 6A current, which greatly broadens the application scenarios of the product to meet the diverse testing needs of product development and debugging, quality control and testing, production automation testing, and teaching experiments.
- Intelligent temperature control fan ensures the ultimate balance of power supply performance, temperature, and noise, as well as over-temperature, over-voltage, reverse polarity and other protections
- 3 independent outputs, 4-digit voltage, and current high-precision display: 10mV/1mA
- Five groups of M1~M5 settings are saved and recalled, long press to store and short press to recall, making the test work efficient and convenient,
- Buzzer switch: switch the buzzer according to the working environment
- Key lock function: prevent accidental touch and wrong setting during normal working process
- Shutdown memory function: Restore the last saved setting value next time the machine is turned on SET; VIEW function: Call preset value with one key
