PRODUCT OVERVIEW

The MCL488 series of multi-channel electronic loads are ideal for ATE system and bench-top applications that require
a multiple channel load with maximum flexibility. Each system consists of a sub-rack housing and modules. The load
modules are rated at 50V, 100V, 400V or 600V and are rated for 175 watt and 350 watt operation. Up to 10 modules
fit into a 19"W x 10.5"H x 23"D sub-rack. The MCL488 is easily upgraded in the field by adding modules.

Once in the sub-rack, the modules are user configurable. The load modules can be paralleled using the paralleling
straps provided, configured either from the front panel or computer bus, and controlled as a single channel. 350 watt
and 175 watt modules may be used in any configuration, providing maximum flexibility. All functions that are
available for a single module are available in the multi-channel configuration.

Complete operation including Constant Current, Constant Resistance, Constant Power and Constant Voltage is available
when operating a single module or when the modules are paralleled. All functions, including linking modules in
parallel through software, are programmed via the user-friendly front panel, IEEE-488 bus or the optional RS232
interface. The front panel simultaneously displays voltage, current, wattage and mode for each installed module.

UP TO 10 CHANNELS CONTROLLED FROM A SINGLE IEEE-488 ADDRESS
