POWER PRODUCTS AND ELECTRONIC

LOADS

The electronic AC loads cover a wide

variety of different voltage, current and

power ranges. All the AC loads are pro-

grammed with 11 different sine, square

and DC waves. With 5 crest factor vari-

ations of each, a total of 55 waveforms

are available. An external input is also

provided to enable the user to amplify

signals from a waveform generator. AC

Loads allow real world operating con-

ditions to be simulated. Typical appli-

cations include circuit breaker, trans-

former & UPS output testing along with

general laboratory and research work.

For system integrators both GPIB and

RS232 interfaces are provided on all the

high power AC loads as standard. IEEE

488.2 is offered as an option on the

lower power units. LabVIEW drivers are

also available. Another useful feature

common across all the AC loads is the

isolated current monitor. This allows an

oscilloscope to be easily connected so

the user can view the load current.

An Adjustable electronic load gives

the test engineer the ability to qualify

designs, check production batches or

service and repair electrical products.

Many applications demand an adjus-

table electronic load. These include

the burn-in of new devices along with

general power supply, battery, fuel cell

and generator testing. Both static and

fully dynamic dc loads are offered. With

dynamic functionality 2 levels of load

current can be set. The rise and fall time

can then be adjusted together with the

time period spent at each level. The

load can also be made to follow com-

plex waveforms by tracking an external

arbitrary oscillator input. Like nearly all

the test and power instruments from

ETPS your chosen dc load can be built

with analogue and computer interfaces

to allow remote operation. LabVIEW

drivers are available for most product

families to simplify assimilation into

wider test systems.
