DESCRIPTION
The 53509 Series Solid-State Power Controllers are lightweight and resistant to damage from shock and vibration. They are
designed to replace electromechanical breakers and solid-state relays. They overcome the problems associated with arcing
and contamination of breakers as well as providing internal protection for overload and short circuit conditions. They provide
Fault and Output State monitoring as well as a controlled Soft Turn-On. The Trip Profile is externally Programmable from
30% to 100% of Rating
Optical coupling between the input and output stages provide effective isolation of 1000VDC. The Power MOSFET Switches
used in the output stage provide low “on” resistance, low offset and minimal internal power dissipation.
Precautions:
Precautions must be taken to limit the transient voltages generated by the inductance in the system wiring and load when a
Overload condition causes the SSPC to turn off. When testing individual SSPC’s, care should be taken to simulate actual
system conditions.
