UDP3000 Series

UDP3000 Series

The UDP3000 Series Programmable DC power supply is a cost-effective programable DC power supply with outstanding performance, reliable output and 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.

LCD interactive interface

Using a 4.3-inch high-definition display screen, it provides users with a man-machine interface with rich functions and simple operation, which can display the current set output voltage/current, actual output voltage/current and protection output voltage/current value of the power supply in real time. The functional interface is simple and comprehensive, easy to operate.

List/Delayer function

With list and delay setting functions, it can set up to 2048 sets of data according to test requirements, and the number of cycles can reach 99999. It is used with waveform templates, which is very convenient for cycle testing and aging testing.

One-key setting for series and parallel

The series-parallel connection between CH1 and CH2 of the main channel can be realized without external connection, which simplifies the connection and makes the test easier.

Rich remote control interface

Standard RS232 communication interface, Ethernet interface, Digital I/O and master and slave USB interfaces, can be controlled by remote connection to Ethernet, or through RS232 and USB, with the host computer software to achieve software control.

What is PPM？

PPM is the abbreviation for part per million. It is used to describe temperature drift value of voltage reference. For voltage reference, 1ppm/℃ refers to the output voltage deviates from its nominal value by one millionth of a degree for every 1°C change in ambient temperature at a reference point (usually 25°C) For example, a voltafe reference has a nominal value 2.5V and TC is ±10ppm/°C, when the ambient temperature changes by 1°C and 10°C for each change in the base of 25°C, its output voltage will become:
2.5V±10ppm/℃X1℃=2.5V±0.000025V
2.5V±10ppm/℃X10℃=2.5V±0.00025V

What is the difference between the line regulation and the load regulation?

Line regulation refers to the effect of the input voltage on the output voltage
Load regulation refers to the effect of load changes on the output voltage

What is the meaning of display resolution, programming resoultion and readback resolution of programmable DC power supply?

Display resolution refers to the minimum voltage, current digits displayed on the screen.
Programming resolution refers to the minimum settable voltage and current.
Readback resolution refers to the minimum voltage and current readback inside the machine.

How to set the constant voltage/current output mode?

Constant current mode：When the current value set by the power supply is less than the current value consumed by the load, the power supply is operating in constant current mode. Ithe setting current value＜Ithe load consuming current value
Constant voltage mode： When the current value set by the power supply is greater than the current value consumed by the load, the power supply is operating in constant voltage mode. Ithe setting current value＞Ithe load consuming current value

How does UDP3000C/S output positive and negative voltage ± 12 V?

The positive and negative voltage outputs are relative to a common reference point. First, connect the positive output terminal of CH1 in series with the negative output terminal of CH2. Select the ground as the reference point and connect both CH1 and CH2 grounds to it. Since the positive terminal is connected to ground at 0 V, use a multimeter to measure the voltage from the negative terminal of CH1 to the reference point—it should read approximately -12 V. Similarly, measure the voltage from the positive terminal of CH2 to the reference point—it should read approximately +12 V.
