Introduction of IPS technology
IPS
is not a UPS
Main
problem to be solved:
Some power disturbance is necessary
to occur because of inherent
limitation in power generation,transmission
and distribution system, and
these unstable factors are sure
to affect the enterprise’s
production. To eliminate the
power disturbance occurd during
production process, we have
designed new system which can
solve the below problem:
electric
fall or peak disturbance (take
up 57% of electric disturbance)
utility
off (take up 7% of electric
disturbance)
over-voltage
(take up 15% of electric disturbance)
impact (take up 21% of electric
disturbance)
applied to protect key equipment
in the production process
IPS power application
mainly applied to emergency
power accident in industry accasion;
food, iron and steel, automobiles,
ceramics, paper, plastics, glass,
pharmaceuticals, coal, petroleum,
chemical industry, electronics,
machinery and electrical, semiconductor
and other industries;
bearing processing, transmission,
manufacturing production lines,
manufacturing processes, industrial
control systems, automation
control, CNC machine tools (CNC),
industrial automation, laboratory
test equipment, monitoring system
and other automated control
and production occasions.

Application
note
|
| About
the output precision |
• |
At
utility normal, IPS is direct,
for it mainly supply to the
industrial load. In the industry
environment, much loads, include
the generator etc., which are
supplied directly by the utility
originally. There is no disposal
need for the voltage when adopting
IPS, especially no request for
voltage stability of the IPS,
which with transducer. So at
utility situation, output=input. |
• |
Disposal
of voltage, such as on-line
UPS double conversion, output
voltage precision is very high,
but also high power loss. |
• |
Few
load ask for high voltage precision,
could adopt UPS local protection,
that is solution of IPS+UPS. |
| About
switch time |
• |
IPS
need 4ms switch time that is safe
to industry loads, truly realizing
uninterruptible. |
• |
When
the power supply stops, due to
inertia, motor continue to rotate
within 10ms. |
• |
Computer
load still can bear the feedback
energy within 10ms because of
energy storage capacitor. |
| About
electric energy feedback |
• |
When
the power supply stops (power
shutdown), motor continues to
rotate due to inertia, resulting
in feedback energy whose instantaneous
release would add to power/UPS/IPS
or other loads and perhaps damage
equipment because of high voltage.
So IPS equipment has feedback
energy absorption device. But
for the application of large
power motor, the configuration
of transducer and feedback energy
device should be considered. |
• |
There
is device similar to feedback
energy absorption device inside
transducer. |
| About
long backup time and battery configuration |
• |
IPS
supply the backup time within
30 minutes. |
• |
If
long backup time needed, load
and environment temperature should
be considered. |
|
| • |
more
than 30 minutes, IPS load
be controlled within 50% |
| • |
Standard
temperature 0~40 °C,if
the application environment
with 40~50 °C, IPS
load be controlled within
50%. |
|
• |
Lengthen
backup time within 15~30 minutes,
with general batteries. |
• |
Lengthen
backup time within 10 minutes,
with high-rate batteries. |
