Technical parameters and indicators of adjustable linear DC stable power supply

1、 Overview

The PPU series DC stabilized power supply is a high stability, stable current linear DC power supply with DC5V/1A output (optional) and a minimum output current of 1mA. The four digit voltage display of the LED digital tube achieves a display voltage resolution of 10mV, The four digit current display of the LED digital tube achieves a resolution of 1mA for displaying current. Especially in the stable current range, the output current stability is extremely high, which is very suitable for working environments that require stable DC low current output. Its output voltage and output current are continuously adjustable within the rated value, and it can work continuously at full load for more than 8 hours.

The PPU series has full protection and alarm functions for overvoltage and overcurrent, and can select models with upper and lower limit alarm functions for output voltage or current. The upper and lower limit alarm values can be set arbitrarily (general models do not come with this function). Our company can customize special power supplies according to customer needs.

The extremely high stability and reliability are ideal choices for research departments, universities, enterprises, and institutions that require high stability DC power supply.

3、 Functional Features

● Constant voltage and constant current: The voltage and current values can be continuously adjusted from zero to the rated value, and the constant voltage and constant current automatically switch

Overvoltage protection: The voltage protection value is continuously adjustable from 0 to 120% of the rated value. When the output voltage exceeds the voltage protection value, it will trip for protection (optional)

Short circuit protection: allows for long-term short circuit or short circuit startup in any working state

Intelligent: Analog control is connected to PLC to form an intelligent voltage and current stabilizing power supply for remote control (optional)

Strong adaptability: Suitable for various loads, with equally superior performance under resistive, capacitive, and inductive loads.

Each power supply has sufficient power surplus space to ensure that the performance and lifespan of the power supply are still well guaranteed even when it operates at full power for a long time.
