AREA & SPECIFICATIONS |
|
| The RBL 488
Dynaload Series features 400, 800, 2000 and 4000 watt models
with wide range IEEE 488 computer programming. Individual
models are designed for low voltage high current application
up to 1000 amperes at fractions of a volt whereas other
models are designed for midrange applications and high voltage
applications up to 1000 volts. Equivalent RBL Dynaloads
are available with RS 232 and Analog programming for laboratory
as well as production applications. All models include easy
to apply master slave parallel capabilities and all higher
power models incorporate variable speed forced air cooling
to assure a quiet environment. |
