Thermal specifications
.
Current according ambient temperature :
Ø
The curve "1"
gives the limits of the product.
The temperature reached are acceptable for the compo-
nents. These values are in compliance with most of SSRs
manufacturers.
In a cabinet with a minimum of ventilation or a non perma-
nent current, these values are correct.
Ø
The curve "2"
gives the limits of the product accord-
ing to EN60947-4-3 with a maximum rise temperature of
50°C (@40°C) for a permanent working and in air calm
( test during 8 hours).
Ø
For a non permanent current, you can calcule the
average power = Pd x duty cycle and check the rise
temperature : Tj = Pd x Rthj/a (Pd and Rthj/a are given
page 2). The junction temperature must not exceed 125°C at
the maximum ambient temperature.The
maximum current
is limited to the size of the alternistor = 25A.
Ø
The thermal constant (Cth) of the product is 7
minutes. That means the rise temperature is only 63% of
the stabilized temperature after a running time of
7 minutes.

Warning
! semiconductor relays don't provide any galvanic insulation between the load and the mains. Always use in
conjunction with an adapted circuit breaker with isolation feature or a similar device in order to ensure a reliable isolation in the
event of wrong function and when the relay must be insulated from the mains (maintenance ; if not used for a long duration ...).

Mounting
Warning
:
only in vertical position. The user should protect heat sensitive materials as
well as persons against any contacts with the heatsink. For non vertical mounting , the load
current must be 50% lower than the rated one . For a good cooling, the SSR needs an air
convection. Less convection air produces an abnormal heating. Keep a distance between
the upper SSR and the lower SSR. In case of no space between two SSR ( zero space
between two SSRs) , please reduce the load current. For further details refer to below :
Ø
Ø
Derating current with no space between SSRs
AC-51 nominal currents are given with a space of 22,5mm between each SSR, for a
permanent current during a minimum time of 8 hours in air calm according to IEC60947-4-3.
In case of non permanent currents or in case of SSRs are mounted with no space, you must
check the heatsink temperature never exceed 90°C. When the SSRs are mounted side to
side ( no space between each relay) a derating current of 25% must be take into account.
A forced cooling ( fan inside the cabinet) improves significantly the thermal performances.

Typical application : LOADS
SIL product is designed mainly for AC-51 résistive load. AC-53 motor current are
also given . For other loads, check the inrush current at turn ON and possible overvoltages
at turn OFF or consult us :
* AC-55b : Incandescent lamps : Inrush current is generally 10 times In during few 10ms.
So limit the nominal current at about 10A.
* AC-55a : Electric discharge lamp : These loads often have overcurrent at turn ON and
overvoltage at turn OFF, so we advise to use 400VAC SSR on 230VAC mains.
* AC-56a : Transformers loads: Very high inrush current up to 100 times In . We advise to
use random SSR.
* AC-56b : Capacitors loads: Very high current at turn ON and overvolatge at turn OFF,
please consult us with 1600V peak SSR with high inrush current.
1~
Fuse
Fusible
Protection :
To protect the SSR against a short-circuit of the load , use a fuse with a I2t value = 1/2 I2t
value specified page 2. A test has been made with FERRAZ fuse ( see page 2).
It is possible to protect SSR by MCB ( miniature circuit breaker). In this case, see applica-
tion note ( SSR protection) and use a SSR with high I2t value (5000A2s minimum)

EMC :
Ø
Immunity :
We give in our data-sheets, the immunity level of our SSRs according to the main
standards for this type of products : EN61000-4-4 &5. You can see the high immunity level
in comparison with the products on the market.
Ø
Emission:
SSRs are complex devices which must be interconnected with other equipment
(loads, cables,etc.) to form a system. Because the other equipment or the interconnections
may not be under the control of
celduc,
it shall be the responsibility of the system integrator
to ensure that systems containing SSRs comply with the requirements of any rules and
regulations applicable at the system level. The very low zero cross voltage (<10V) improves
the conducted emission level in comparison with most of SSR on the market with zero cross
voltage higher than 25V. Consult
celduc
laboratory which can make some tests in your
application.
