Liquid Cooled AC/DC
The LiquaBlade™ Series are the latest breed of industrial grade, high power three phase AC-DC power supplies engineered by Astrodyne TDI. These rectifiers combine advanced DC power processing, the latest silicon carbide semiconductors, patented liquid cooling and sophisticated microprocessor controls, resulting in up to 16.5 kilowatts of power in a single 1U (1.75” height) rack style package. The high frequency switch-mode design employed in LiquaBlade™ offers full active power factor correction, near unity power factor and excellent output responsiveness. The wide operating AC input range of 380-480V 50/60Hz permits global three phase application usage without the need of an external step down transformer. LiquaBlade is fully programmable – a perfect solution for applications that require a flexible power supply solution for their unique requirements.
Air Cooled AC/DC
The Mercury line of industrial supplies from TDI Power are a series of AC/DC and DC/DC modules that are building blocks for reliable power solutions to suit a wide range of applications in the industrial market.

Mercury AC/DC rectifiers and DC/DC modules are available in three different mechanical package sizes and output power levels including 800W, 1200W, 2700W, 3800W and 4300W. Using a mechanical design that separates the power module from a hard wired connection shelf assembly, hot swapping of individual units is made simple. This is beneficial when paralleling large numbers of modules for redundancy or if flexibility for expansion is required.

With flexible input voltage ranges, high power and wide modularity capabilities, the Mercury family is an ideal choice for distributed power architectures and standby battery systems. Through TDI’s 50+ yrs experience in power electronics and our proprietary Highly Accelerated Stress Screening (HASS) processes, customers can expect years of performance with high MTBF and low MTTR. Rely on TDI Power for your next project that mandates reliable, accurate and flexible power.

Mercury Flex - Programmable DC Voltage & Current Source

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, 0-85V, 0-125V, 0-400V. 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 14VDC 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.

DC/AC Inverters
TDI Power offers two standard series of modular DC-AC Inverters that provide True Sine Wave outputs from 24 Vdc or 48 Vdc sources (or higher in some cases). The modules are used in a variety of applications including Telecommunications, Data Center, Alternative Energy, Industrial, and COTS.
Standard features include:

  • True Sine Wave Output, THD < 5%
  • Hot Bus Plug In
  • Automatic Sync and Current Share
  • Demonstrated MTBF >1M hours
  • In addition to the hot plug LPE and LCE series TDI Power produce inverter solutions for many other applications including portable power, commercial airborn and vehicle power.
Outdoor Sealed
Environmentally Sealed Power Modules (ESPMs) are ideal for industrial applications. Leveraging TDI Power’s vast experience in demanding Industrial, Military and Aerospace markets, this product delivers the highest standards of dependability, reliability and value.

All electronics within the ESPM’s aluminum chassis are fully sealed and submerged in oil, making the ESPM convection cooled and NEMA rated to be watertight, submersible, dust tight, corrosion resistant, sleet resistant and ideal for hazardous locations. The internal components stay cool and reliable without the need for fans or blowers.
