The Instek PEL-2002A is a multiple channel programmable DC Electronic Load with a dual modularized structure. This product is designed to meet the test requirements of high-speed semiconductor devices in the market today. The PEL2000A 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-2002A is a 2-slot mainframe with master control unit to hold 2 load modules.

The Sequence function allows each channel to change load following a pre-defined arbitrary waveform sequence at a selectable speed up to 100μs per step. Further more, every channel can proceed with its respective arbitrary waveform sequence and work together with others under a clock control to provide multi-channel actual-device simulation. This is one of the most powerful features of Instek PEL2002A to simulate the load operations of a multi-output power supply.

Under Dynamic mode, the load current or load resistance bounces up and down between two preset levels at a selectable speed up to 25μs per step. This provides standard test procedures for the verification of a power supply’s response to very quick load changes. The PEL-2002A provides USB Host/Device and RS-232 interface as standard and GPIB optional for external control and system configuration
