ONE: FEATURES AND OPERATION OVERVIEW

INTRODUCTION

The PLA and PLW Series Programmable DC Electronic Load (eLoad) from AMREL offers a complete solution to the
electronic load system requirements. This instrument was designed to assist in the development and testing of new
products, as well as is being a standard instrument for automatic test systems and evaluation of dc power supplies,
batteries, and power components. Other applications include use as a power circuit breaker or crowbar, high current
function or pulse generator, fuel-cell and photovoltaic cell test, and de-energizing super conducting magnets. This
instrument uses advanced power MOSFETs to d issipate the input power. The electron ic load consumes minimum power
to control maximum input power handling capability. Complex circuits are used to control the power balance and
dissipation of the MOSFET. This control circu it also supports the Constant Voltage (CV), Constant Current (CC),
Constant Resistance (CR), and Constant Power (CP) modes of operation. It comes with Standard Commands for
Programmable Instrument (SCPI) commands, remote monitoring of input voltage and currents is a standard features. The
electronic load can be used either on your bench or in a standard 19 in. (483 mm) rack: occupies 3.5" - 8.75" (2U - 5 U)
of vertical rack space. Designed for continuous use in standalone or systems applications, this electronic load is typically
used to evaluate DC equipment, control circuits, or burn-in power applications.
