The New Programmable AC/DC Power Supply from Astrodyne TDI provides 3.8kW of power digitally controlled as either a current or voltage source up to 450V or 135A.

Mercury Flex

Ideal for use in industrial applications

The Astrodyne TDI 3.8kW Mercury-Flex is an ideal rectifier solution for applications that require a flexible, digitally controlled industrial power supply with a universal 90VAC to 264VAC 50/60Hz single-phase input, and a wide choice of adjustable DC output voltage range models: 0-28V, 0-56V, 0-450V. Advanced power conversion techniques deliver efficiency of up to 93%, with a Power Factor of 0.97 or better. Additionally, the Mercury-Flex series features a fixed 12VDC auxiliary output, useful for powering miscellaneous user circuits.

Using the digital CAN-Bus or Ethernet interface, Mercury-Flex can be factory pre-set or field programmed to operate in a constant voltage, constant current, or constant power mode. The digital read-back feature provides output voltage and current values, operating temperature, and protection alarm status.
For higher power applications, Mercury-Flex rectifiers can be easily connected into parallel current sharing groups with the aid of a four module shelf assembly, enabling designs of upwards to 228kW in a single universal 19" rack (30U).

With stringent design rules per NAVSO P3641A and Highly Accelerated Stress Testing of all production units, the Mercury-Flex system benefits from a heritage of power products with greater than 1 million hours of field demonstrated MTBF. Designed with over 50 years of power conversion experience, and built in the Astrodyne TDI ISO9001 certified factory, Mercury-Flex is your high reliability solution for modular flexible power.
