New DIN Rail AC inrush current
limiters for capacitive & inductive loads
P
owersolve’s new PSICL series is
a low-cost range of peak inrush
current limiters designed for
capacitive and inductive loads in a
variety of applications.
These include installations across
complex automation systems and
machinery as well as isolation
transformers or LED lighting applications
where they are particularly useful
because you can have a large number of
LED driver power supplies operating in
parallel and all taking high peak currents
together on switch on which can cause
circuit breaker to trip.
The PSICL series is a true current limiter
and cuts off all peak currents when
starting loads under practically every AC
condition.
Extreme conditions can occur on AC lines
in the event of a break in the supply
and when power returns, high current
peaks can often cause havoc and will trip
circuit breakers.

In decentralised areas, this will often
lead to increased maintenance costs as
the breakers require re-setting. Both items are DIN Rail mounted and
internal circuitry is identical for both
versions.
The PSICL current limiter prevents this
happening and can result in reduced
cable cross section used and smaller and
faster circuit breakers. We also have the existing full ESB101
range of inrush current limiters available
which are suitable for applications
from 16A to 30A single phase input,
in either 115VAC or 230VAC voltage
input versions. These are suitable for
capacitive loads such as LED lighting etc.
The PSICL Series is available in three
230VAC single phase models with
continuous operating current rating of
12A, 16A and 25A. Current limiting time
is 100-500mS with repeat intervals of
1000mS.
They have an operating temperature
range of --40ºC to +70ºC and conform
to EN60950-1 and EN61000-6-2,3
standards and are CE and RoHS. MTBF
figures are 300,000 hours. The PSICL is a
housed in a low profile V0 flammability
rated plastic case measuring 91H x 71W
x 57Dmm. The same design designated
PSESB Series is also available in a very
slim width enclosure with measurements
of 100H x 22.5W x 112Dmm.
Also available are 3 phase AC input
versions of 16A and 32A continuous
rating. The ESB00163 (16A) and
ESB00323 (32A) three phase input series
operate with input voltages of 200, 400
& 500VAC and are for inductive and
capacitive loads.
