1 Reversing output polarity may cause permanent damage

2 The (circuit breaker) I2t function immediately terminates surge currents per Figure 2 or 3. DESCRIPTION: This Isolated DC IPC is a low mass open construction DC switch intended for applications within an enclosure. In addition to load switching, the incorporated I 2t overload protection / fault protection provides a circuit breaker function. A status output signals output switch conditions of On / Off and Overload. An I 2c interface communicates switch voltage, current and base plate temperature. Transformer and opto -coupling isolate the output to all Control / Status and Data lines and base plate to 1,500 VDC. Power MOSFETs output switch provides soft start and low On voltage drop for cool operation. The Logic Control input operates from a bias supply of 18 to 32V. This IPC combines the functionality of a relay and circuit breaker. Output current is monitored for over-current with an I 2T trip curve. Fault currents beyon d the I 2T trip limits are terminated instantly. Over-current conditions include Over -Load and Shorted Output during Turn -On. An open -collector Output Status is available to indicate the State of the Output Switch MOSFET s. The output remains blocked until the short is removed and the unit reset. Output Status is an Active Low for Control Off or Tripped condition and High into a pull up resistance for a (Control High) Normally On Output State. Controlling the IPC Off then back on resets a Tripped condition. Application:  270V 60A Power Switching

Allow 100 seconds between overload or shorted load restarts for full current startup. 3) Input transitions should be “bounce-less contact” with transitions of <1 msec. 4) Inductive loads must be suppressed for operational command transients and Internal Fault shutdown times as short as 5µs.
