The PEL-2004A is a 4-slot mainframe with a master control unit to hold 4 load modules. 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. 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. * Sequence function to do high Efficient load simulations * Flexible configuration with mainframes and plug-in modules * Multiple independent load inputs up to 8 channels in a mainframe * Parallel connection of inputs for increased load capacity * Parallel connection of inputs for static and dynamic tests * Multiple channels run for dynamic tests under one clock control * Maximum rated power for low range high resolution CC tests * Von setting and Von on/off for start-up Von tests * Program mode to create work routines for repetitive tests * OPP/OCP/OVP/OTP protections * External channel control/monitoring via an analog control connector * Multi-Interface USB Device / Host, RS-232C, and GPIB (Optional) * Multi-mainframe link up to 5 mainframes in a system * Manufacturers part no.
