These state of the art SSPCs are designed for use in Power Controller applications. These SSPCs utilize the latest technology to provide low Onresistance output with complete short circuit and overload current protection. SSPCs are electronic replacements for the conventional electromechanical circuit breakers. The remote features allow the SSPC to replace these circuit breakers as well as a load switching relay. They reduce component count, system weight and cost and increase system reliability.

A HIGH signal will turn the device ON. A low signal or an OPEN condition will turn the device OFF, If the device trips OFF, the device is reset by cycling the CONTROL to OFF then ON again. • Overcurrent operation. The device will trip (i.e., turn off) if the load current exceeds the requirement of FIGURE 4. Once the device is tripped, it will remain OFF indefinitely, until the overcurrent condition has cleared and the device is reset. • The output power section of the SSPC is isolated to the control section, and both input and output sections are isolated to the case. Load(s) can be located on either side or both sides of the SSPC. In other words, the SSPC is capable of high side switching and low side switching. WIRING DIAGRAM FIGURE 5 NOTES • • • • Page 14 Unless otherwise noted all tests shall be performed with Vcc = 5.0 Vdc, Vline = 28 Vdc, ILoad = Rated Current. The transition time for the control signal shall be less than 1.0 msec in application. Maximum input repetition rate into shorted load is not to exceed 1 Hz. Inductive load must be diode suppressed. System series inductance in the short circuit mode shall be less than 30 micro Henry.
