"Evolving for Excellence, Unwavering in Quality."

The GPE-X323A series DC power supply is the latest iteration of the GPE-X323 series, building upon its proven quality and reputation. This upgraded model refines precision with an encoder switch for more accurate voltage and current adjustments. Additionally, the digital control system has been streamlined—reducing six rotary knobs to just two—enhancing the front panel’s simplicity and ease of operation. 

A key improvement in this iteration is the overvoltage protection (OVP). Unlike the previous GPE series, which relied on a single maximum voltage threshold for activation, the new A series allows independent OVP voltage settings for each channel: CH1/CH2：1 V to 36 V；CH3：5.5 V (GPE-3323A)；1 V to 6 V (GPE-4323A)；CH4：1 V to 16 V (GPE-4323A).

These refinements make the A series a more flexible and precise for multi-channel applications.

Common features of GPE-X323A and GPE-X323 series

• The X in X323 can be 2/3/4, representing dual-channel, triple-channel, or quad-channel.
• Output power from 192 watts to 217 watts
• High Resolution
• Low Noise
• Voltage Recovery Time：≤ 100 µs (50 % load change, minimum load 0.5 A)
• Key Lock Function

Tracking Series / Parallel Operational

In addition to independent output channels, the GPE-X323A series provides automatic tracking series and parallel connection function. The series and parallel connections allow power supplies to output 32 V/6 A (Parallel connection) and 64 V/3 A (Series connection). The CH1 and CH2 of GPE-2323A / GPE-3323A / GPE-4323A models operate the series and parallel connection function.

They all claim to be dual-channel power supplies, but the devil is in the details, and details determine value.

The devil is in the details On the design details of dual-channel DC power supplies

key Lock

When performing a long reliability experiment or the user temporarily leaves the experiment site, if others change the power settings, it may cause the experiment to be interrupted or the DUT to be damaged. The user can activate the key lock to ensure that the experiment is not affected by others.

Remote Control (Remote I/O) for Output On / Off Function

The GPE-X323A series provides the Output On/Off function to prevent DUTs from unnecessary damages caused by the pre-output when connecting a DUT with a power supply. Users must preset voltage and current parameters and ensure that all connections are correct. Then, via manual control on the front panel, users can activate the Output On/Off.
