DESCRIPTION

The VPTVME series of isolated VME power supplies is an effective COTS solution for many demanding high reliability applications. A wide input voltage range accommodates nominal 28V inputs including avionics, mobile, ground systems, and other applications. High efficiency, low input and output ripple, fixed operating frequency, and built-in EMI compliance simplify system design. Incorporating VPT’s proven design and rugged packaging heritage ensures long term reliability. The VPTVME series is intended for harsh environments including severe vibration, shock and temperature cycling. Testing is to MIL-STD-810, and MIL-STD-883 as detailed. This assembly is designed and manufactured in the USA in a facility certified to ISO9001, J-STD-001 and IPC-A-610.

PRIMARY INHIBIT: The PRIMARY INHIBIT pin is used to enable / disable all outputs except for the 5V Standby output. The PRIMARY INHIBIT input is internally pulled up to 2.94V ±10% and is referenced to 28VIN RTN. If PRIMARY INHIBIT is driven high or left open, the outputs will be enabled; if pulled low, the outputs will be disabled. Cycling the PRIMARY INHIBIT pin will also clear any fault condition. SECONDARY INHIBIT: The SECONDARY INHIBIT pin is used to enable / disable all outputs except for the 5V Standby output. The SECONDARY INHIBIT input is internally pulled up to 2.94V ±10% and is referenced to 5V STBY RTN. If SECONDARY INHIBIT is driven high or left open, the outputs will be enabled; if pulled low, the outputs will be disabled. INPUT GOOD: The INPUT GOOD pin / LED indicates the condition of the input line. The INPUT GOOD pin is an open collector output and is referenced to 5V STBY RTN. Under normal operating conditions the INPUT GOOD pin is pulled low and the LED is lit green. If the input line drops below the UVLO Turn Off threshold, the INPUT GOOD pin will be open / high impedance and the LED will change to red. OUTPUT GOOD: The OUTPUT GOOD pin / LED indicates the condition of the outputs. The OUTPUT GOOD pin is an open collector output and is referenced to 5V STBY RTN. Under normal operating conditions the OUTPUT GOOD pin is pulled low and the LED is lit green. If an UVLO, Over Current, Over Voltage, or Over Temperature condition occurs or if the unit is disabled, the OUTPUT GOOD pin will be open / high impedance and the LED will change to red. The OUTPUT GOOD pin will also be open collector and the LED will be red during start-up for approximately 250ms. OVERTEMP: The OVERTEMP pin / LED indicates the unit’s mounting rail temperature. The OVERTEMP pin is open collector and is referenced to 5V STBY RTN. Under normal operating conditions the OVERTEMP pin is open / high impedance and the LED is lit green. If the unit’s temperature exceeds the over temperature threshold, all outputs except the 5V Standby will latch off, the OVERTEMP pin will be active low and the LED will change to red. The LED indication will self clear when the temperature returns to normal however the latch condition will need to be cleared by either cycling the PRIMARY INHIBIT pin or by cycling the input line below the UVLO Turn Off threshold. OVER CURRENT: Each output is protected against an over current condition. The output current is limited to approximately 125% of rated output current. A sustained over current condition will trip the over current latch, latching all outputs except the 5V Standby off. The latch condition can be cleared by either cycling the PRIMARY INHIBIT pin or by cycling the input line below the UVLO Turn Off threshold. OVER VOLTAGE: Each output is protected against an over voltage condition. The over voltage protection is activated if an output exceeds approximately 120% of its output voltage setpoint. An overvoltage condition will trip the over voltage latch, latching all outputs except the 5V Standby off. The latch condition can be cleared by either cycling the PRIMARY INHIBIT pin or by cycling the input line below the UVLO Turn Off threshold. REMOTE SENSE: The main outputs each have remote sensing capability. The remote sense pins should be connected to their respective outputs. They can be connected on the backplane to compensate for drop across the connector, or at the load. The sense lines can compensate for up to 0.5V total drop (output and return). The sense lines should be routed with their outputs to minimize noise pickup.
