Soft start for reduced EMI. High efficiency with less than 0.8V drop at full load. Compact panel mount “Hockey Puck” style package. No Output current de-rating is required for base plate temperatures of -40ºC to +80ºC. SPST, normally open power controller. UL94V-0 approved clear IP20 touch safe protection cover. MIL-STD-704A through E and MIL-STD-1760E I 2t compliant. TTL / CMOS compatible Switch Status. AC devices designed for inductive load power factors to 0.75. AC devices designed with integrated load switching transient suppression. Description: The IPC combines both relay and circuit breaker functions. The Isolated IPC is mechanically similar to the standardized industrial Solid State Relay. The functions include Soft Start load switching, I 2t overload / fault protection that provides circuit breaker function to MIL-STD-1760E and load status signaling indicating switch ou tput conditions of ON, OFF and Overload. Inductive and optical coupling between the input circuits and output provides isolation of 1,500 VRMS. Power MOSFET output switches provide soft start and low ON voltage drop for improved thermal characteristics. The input Control logic operates from a V DD of 5 to 32VDC. (See Figure 5) Output current is monitored to control outputs during over- current conditions (see the I 2t trip curves). Over-current conditions include Over-Load and Shorted Output during Turn- On. Open-collector Output Status indicates the state of the Output Switch MOSFET load driver. The output remains OFF until the short is removed and the unit’s control line is toggled OFF and back ON. Locking the output OFF on an error condition prevents damage to the controller and further system damage caused by the short circuit. Output Status is an Active Low (Open Collector) for Controller OFF or Tripped conditions and High (pull up resistor) for a normally ON output state. The IPC is designed for rated current over a Baseplate Temperature Range of -40ºC to +85ºC. This includes the operations of Soft Start at Command ON and Trip OFF on Over Load or Fault Conditions. Applications: Aerospace Ground Support Equipment. Industrial and Commercial Lighting Systems. Commercial Test Equipment. Manufacturing Equipment. Energy Exploration Systems and Equipment. Communications Systems and Plants. Aircraft and Avionics Systems. Automation Equipment. Fabrication Equipment. Vending Machines. Selective Power Distribution. Laboratory Test Systems. Food Processing.

High side (5) or low side (6) switch connections are facilitated by full isolation between Input Logic, Base Plate and Output Switch Connects. Logic level Control input circuit drives an Opto-Coupler across the isolation to the switch circuits and a second Opto-Coupler returns a signal for the Open-collector Status Output. Control (4), Status (1), V DD Input Power 5-32VDC (2) and GND (3) make up the Input isolation group. A filtered DC to DC converter is driven from the input V DD to power the secondary side circuits. The Output circuit consists of Output MOSFETs connected at their sources through a current sense resistor and their Drains offered as the output switch. In the DC version, the sense resistor is monitored by the I 2t detection circuit. A Fault Latch receives inputs from the I2t detection circuit, the power supply and the control Opto-Coupler. Based on these inputs the Gates of the output MOSFETs are controlled. The Fault Latch also provides the Status signal. In the AC version, an absolute amplifier rectifies the output current (voltage) of the sense resistor by the I2t detection circuit. As in the case of the DC version, a Fault Latch receives inputs from the I2t detection circuit, the power supply and the control Opto-Coupler. Based on these inputs the Gates of the output MOSFETs are controlled. The Fault Latch also provides the Status signal.
