High Density DC 30A Lab Power Sources

Introduction:

The SP-1U/2U series of high-performance programmable DC power supplies haveovercurrent/undercurrent/overvoltage/overheating/overpower/undervoltage protection, grid fault protection and fault storage functions, as well as power-off protection functions. The unique Foldback protection function is used to turn off the output when the power CV/CC is switched, so as to protect some DUTs that are sensitive to voltage overshoot and current overshoot.

APM technologies product line includes programmable Power Supplies. AC Power Supplies, DC Electronic load and coming new DC power supplies.

♦ Adjustable rising and falling time

♦ LIST mode programming
♦ Low ripple and low noise
♦ High resolution and high accuracy
♦ Support multiple protections

♦ Remote sense function
♦ Analog control interfaces
♦ Built-in USB/RS232/RS485 interfaces; LAN and GPIB is optional;

Functions and Advantages

SHORT MODE Function

This function is applicable to cable/fuse current carrying capacity test, when activated, the power supply will shutdown the short circuit protection function and maintain ultra- low voltage to output rated current.

Timer Control function

This function is applicable to unattended occasions, activate the timer and the output, the screen will show the countdown of the timer. Once it reaches down to zero, the supply will turn off the output automatically. And the full protection of the power supply will make sure the safe usage of this function.

External Control Function

This series power supply can offer external voltage/ potentiometers control output, can be controlled by external voltage (0~5V) or external potentiometers (5~10K) in order to remotely adjust the power supply voltage and current regulation settings and the output status of the power supply.

Quick Recall Function

Support to recall the stored parameters directly by the numeric keys on the front panel.

Firstly, user stores the frequently used data in the power supply's memory, press the numeric key directly after entering the quick

recall mode, can quick recall the data which are stored in 【1】~【9】.

Anti reverse irrigation/Power Sink Function

This series power supply has protection against reverse irrigation, so as to cut off the current of DUT in a certain test condition to the direction of power supply, and prevent the damage to the power supply hardware circuit from DUT.

Meanwhile, this series power supply comes standard with short circuit copper sheet, When the test requires the power supply to absorb the spike generated by DUT to ensure the safety of the operation, the short-circuit copper piece can be connected, and the energy is absorbed by the output capacitor inside the power supply and other circuits.
