Overview
\nDesigned for harsh environment applications, the Aitech P221 is a versatile and reliable 6U VME power
\nsupply providing VME systems with an exceptionally wide input voltage range and all standard VME
\noutputs and assures excellent load and line regulation.<\/p>\n
The P221 input power voltage can vary from 16 Vdc to 36 Vdc, with a drop to 14 Vdc for up to 45 seconds,
\nand fully complies MIL STD 704A and D for 28 Vdc operation. For ultimate EMI reduction, an input line
\nfilter is used to reduce the input reflected ripple.<\/p>\n
The power supply asserts four VME 64X compliant voltages, each featuring an extended holdup time of
\n50 ms. The four outputs are provided by three DC-to-DC converters, with a total power rating of up to 175 W, and feature a minimum of 500 V isolation from input to output, thus eliminating any possibility of ground loops.<\/p>\n
All outputs are individually protected against short-circuit and overvoltage. The power supply asserts all
\nthree VME 64x compliant control signals, namely SYSRST, SYSFAIL and ACFAIL. The 5 Vdc output
\ncarries sense lines for remote sensing.<\/p>\n
The power supply provides temperature measurements and alarms, as well as DC fan output controlled by
\ntemperature. In addition the P221 is equipped with a sophisticated BIT logic that monitors inputs and
\noutputs, the temperatures, the fan status, and provides the VME and BIT status signals.<\/p>\n
In addition, the P221 features four visible LEDs to show proper output voltages and an external ON\/OFF
\nsignal for remote shutdown.<\/p>\n","protected":false},"excerpt":{"rendered":"
