P221
Designed for harsh environment applications, the Aitech P221 is a versatile and reliable 6U VME power supply providing VME systems with an exceptionally wide input voltage range and all standard VME outputs and assures excellent load and line regulation.
The P221 input power voltage can vary from 16 Vdc to 36 Vdc, with a drop to 14 Vdc for up to 45 seconds, and fully complies MIL STD 704A and D for 28 Vdc operation. For ultimate EMI reduction, an input line filter is used to reduce the input reflected ripple. The power supply asserts four VME 64X compliant voltages, each featuring an extended holdup time of 50 ms.
