Four Slot Programmable DC Load Mainframe (Modules Sold Separately)
The PEL-2004A and PEL-2002A are multiple channel, programmable DC electronic loads with a modularized structure. The PEL-2000A 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 follow this shift, power supply design, quality inspection, and characteristic certification using high-speed performance loads have become necessary.
The PEL-2000A 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-2004A is a 4-slot mainframe with a master control unit to hold 4 load modules, while PEL-2002A is a 2-slot mainframe with a master control unit to hold 2 load modules. When the PEL-2004A is configured with 4 load modules rated at 350W each, the PEL-2000A series is able to sink up to 1.4kVA of power.
Mainframes
Instek offers two types of mainframes in the PEL-2000A series:
- PEL-2002A – two slot
- PEL-2004A – four slots
Load modules
Four modules are available for the PEL-2000A series. Please note, modules are sold separately.

Automatic sequence function
The Sequence function allows each channel to change its load sink according to a predefined sequence at a rate of up to 100µs 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-2000A 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 25µs per step. This is often used as the standard test procedure to verify the response of a power supply to quick load changes.
​
Parallel dynamic loading
All the load channels in a PEL-2000A 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 25µs 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 high-power power supplies without the need for a dedicated high power electronic load.
​
Frame link
The PEL-2000A Series allows multiple mainframes to be linked together with standard MIL 20-pin connectors to provide higher power load capacity. A maximum of 5 mainframes, including one master and 4 slaves, can be chained together to give a 7kW load capacity for high current and high power applications.
