The
50A-3PH is a three phase
injection system providing
commissioning and maintenance
engineers with a flexible system
for testing protective systems.
It has an easy to understand
panel layout and a simple user
interface. The status of every
function can be seen at a
glance, and there are no complex
menus to navigate.
|
|
|
|
The
unit has a range of outputs
allowing injection of currents
as low as a few mA and as high
as 50A. Voltages up to 18V are
available on the main outputs.
Three true RMS metering ranges
are provided, allowing the full
scale of the meter and trip
level to be set independently of
the selected output. Industry
standard safety connectors are
used on all inputs and outputs
for convenience, reliability and
safety.

|
|
The
50A-3PH is comprehensively
protected by overcurrent, duty
cycle and thermal trips, and
keeps the user fully informed of
any trip condition. Auxiliary
outputs and inputs are fuse
protected.

The
back-lit display on the 50A-3PH
is bright and clear with a wide
viewing angle. The results of a
test can be seen here as they
appear on the display
|

|
|
An
auxiliary metering input is
provided and can measure
voltage, current, frequency, and
the phase between any of the
current outputs and an external
voltage or current.
|
|
|
|
The
timing system is very flexible
without compromising ease of
use, allowing trip times, reset
times and reclose times to be
quickly measured to a high
degree of accuracy. Two
independently isolated contact
inputs are provided, and the
timing system may also be used
as a stand-alone timer.
