Benchtop programmable dc loads

WESTEK Electronics has released the Array Electronics 3700 series of two benchtop dc loads with flexible keypad and rotary controls as well as computer interface via RS232 or RS485.

The 3700 series are suitable for a range of tasks including battery and power supply testing.

Windows-based operational software on a CD is supplied as standard and includes ActiveX for VC++, VB, Delphi and LabView drivers. The Array Electronics loads are therefore suited to ATE applications as well as for engineering and calibration tasks, etc.

Operational safety is assured via password access and operating parameters can be set via a keypad, rotary control with readout of settings on the electronic load's LCD, or remotely via computer.

Main functions include constant current, constant power or constant load resistance set-ups. The loads have internal memory permitting the setting up of ten pre-defined operating parameters.

Array Electronics power supplies are available in two versions with respectively 150W and 300W capacity and capable of sinking currents to 30A, with a maximum input voltage of 360V dc.

The Array Electronics loads are protected against over-voltage, over-current, over-power consumption, over-heating and polarity reversal.

The 3700 series measure 250mm x 212mm x 88mm and weigh 5kg. They are suitable for rack-mounting or benchtop use. The dc loads are powered from 110V or 220V ac.
