The Aitech P233 is a versatile and reliable VITA 62 compliant 3U power supply designed for harsh environment applications, with a wide input voltage range and a total power output capacity of up to 600 W.
An optional sharing mechanism, per VITA 62, enables two P233 power supplies to be operated in parallel in order to provide redundant operation (ORing) or to provide a maximum power output of up to 1200 W.
Input to output isolation eliminates any possibility of ground loops, and the main output supplies (+3.3 V, +5 V, and +12 V) have remote sense lines to ensure voltage stability for high current loads. The P233 also includes numerous protection mechanisms both for input power and for output power supplies.
EMI/RFI protections include the P233 heatsink, which provides enhanced EMI/RFI shielding of on-board components, and the on-board second stage EMI/RFI filter for input power (designed to be used along with a system-level first stage filter).
On-board logic, control functions, are user-defined pins are managed by an FPGA that can be field customized (contact an Aitech representative for more information).
An optional capacitor bank provides hold-up time to enable orderly system shutdown in the event of power failure. The capacitor bank also includes a backup battery to provide VBAT per VITA 62, in order to power a system real-time clock when the system is powered off.
