Why use SOLICON DRC Series Contactors?
DEC
Solid State Switching solutions make no acoustical noise when the output changes states. This is highly
desirable in many commercial and medical applications.
DRC Series are “all” Solid State Contactors with no moving parts. Therefore, there is no wear out of the
output since there are no mechanical “contacts”. The typical life expectancy of a DRC Series Solid State
Contactor may be more than 50 times that of an equivalently rated electromechanical contactor, making
them ideal for repetitive cycle applications.
DRC Series Solid State Contactors are not susceptible to erratic or unreliable operation when operating
in tough environments. Vibration can affect EMR contactor performance in certain installations, but not
DRC Solid State Contactors.
DCR Series Solid State Contactor outputs do not “bounce” or create arcs when switching on or off. Thus
electrical transients commonly created by contact bounce and arcs of EMR contactors are not created
when the DRC switches loads on and off. Additionally, the zero current turn off feature of the DRC further
reduces electrical transients created by EMR contactors turning off motor and inductive loads.
Significant energy savings can be achieved through the more precise load control made possible by DRC
Solid State Contactor performance. By combining the DRC with precise control circuitry and appropriate
programming, load on times can be minimized through frequent on/off cycling, thus providing maximum
system efficiency simply not possible with EMR type contactors.
DRC Solid State Contactors are designed to meet IEC 60664-1 pollution degree level 2 and will operate in
most control applications. DRC Contactors are impervious to magnetic fields and offer up to 4 Kv optical
isolation to insure that line transients do not damage the Contactor or get transmitted to sensitive low
voltage control equipment.
SOLICON DRC Series Contactors are lighter compared to equivalently rated electromechanical
contactors. SOLICON’s typical weight of 196 grams compares favorably to 320 grams for similarly rated
EMR contactors, thus reducing both equipment weight and inbound and outbound freight. Reversing
applications benefit even more since 2 EMRs and an interlock are required for such applications.

The compact IEC style package of the DRC Contactor permits motor reversing control in half the space
required for EMR type contactors performing the same function. That is a 50% savings in cabinet space!
Space Saving Compact Package
DRC Series Solid State Contactors require very little input power (coil current for EMR contactors) to
switch large load currents. Typical input current for the DRC Series is 10 mA verses 200 to 300 mA for EMR
contactors, corresponding to greater than a 90% reduction.
