PEL-2000 Description

Satisfy All Your High Speed Load Simulation Needs

The PEL-2004 and PEL-2002 are multiple channel, programmable DC electronic loads with a modularized structure. The PEL-2000 Series is designed to meet the continuing shift toward high speed operation in today's semiconductor market. As the power supply units, DC-DC converters, and batteries that drive semiconductor circuits to follow this shift, power supply design, quality inspection, and characteristic certification using high-speed performance loads have become necessary. The PEL-2000 Series includes two types of mainframes and 4 types of load modules to accommodate users' requirements in a flexible manner. Any load module combination can be used with a mainframe to tailor a test system based on the number of channels, and the maximum load power, voltage and current of each channel. Multiple loads can be connected in parallel to provide a higher-power load to test higher power supply outputs. This flexibility significantly reduces the investment needed for future projects that have different power requirements. The PEL-2004 is a 4-slot mainframe with a master control unit to hold 4 load modules, while PEL-2002 is a 2-slot mainframe with master control unit to hold 2 load modules. When the PEL-2004 is configured with 4 load modules rated at 350W each, the PEL-2000 series is able to sink up to 1.4kVA of power.


The Sequence function allows each channel to change its load sink according to a predefined sequence at a rate of up to 100 s per step. Each sequence is able to run concurrently, under the control of one clock. This is one of the most powerful features of the PEL-2000 Series as it is able to realistically simulate a multi-output power supply load. Under Dynamic mode, the load current or load resistance pulses between two preset levels at a pre-defined speed up to 25 s per step. This is often used as the standard test procedure to verify the response of a power supply to quick load changes.
The picture above is an example of a sequence used as a load profile for a single output switching power supply. A load profile is programmed to simulate the current draw of a power supply load. By using a current probe to acquire a current waveform, the PEL-2000 is able to evaluate the performance of a power supply based on the load sequence that is programmed. An oscilloscope is then used to display the result.


All the load channels in a PEL-2000 mainframe can be connected in parallel to perform any combination of static or dynamic loading. Under Dynamic mode, the load current or load resistance pulses between two preset levels at a predefined speed of up to 25 s per step. When the channels are connected in parallel, dynamic tests are synchronously clocked. The ability to perform parallel dynamic loading gives you the flexibility to perform dynamic tests to highpower power supplies without the need for a dedicated high power electronic load.
