SynQor’s VPX power supplies are compliant with VITA 62, MIL-STD-704, and MIL-STD-461 for 28 V-in systems. The VPX-3U-DC28P-002 power supply has a maximum total output power of 500 W. It has overcurrent, overvoltage, and overtemperature protection. The system – which employs current sharing on VS1, VS2, and VS3 – is VITA 47 and MIL-STD-810G compliant. The power supplies also carry electrostatic discharge protection and are designed to resist shock, vibration, rapid decompression, corrosion, and fungus. Additional features include -40° C to +85° C extended operating temperature, no electrolytic capacitors, and remote-sensing capability.
A control feature on the power supply includes ENABLE, which is used to turn off all of the output voltages when it is high, including +3.3 V_AUX. When it is pulled low to SIGNAL_RETURN, +3.3 V_AUX, power will be turned on and the status of the other outputs will be dependent on the state of INHIBIT. The INHIBIT control feature is used to turn off all the output voltages except +3.3 V_AUX. The FAIL control feature signal is used to indicate a failure has occurred. The SYSRESET signal is an output generated from the module and is used to indicate that startup has completed.
