Three-Phase Performance from a Single-Phase Power Supply
Behlman Electronics Inc. has created the VPXtra™1500CS3 to support high-end industrial and military applications where only single-phase ac power is available. Now users can choose either the Behlman VPXtra™1500CS for applications powered by a three-phase ac power source, or the new Behlman VPXtra™1500CS3 for applications powered by single-phase ac power source.
Both units are VITA 62, Open VPX compliant 6U front-end modules that deliver 1500 Watts of 33Vdc power, and have input current harmonics that comply with MIL-STD-461 (CE101) and MIL-STD-1399. In addition, these front-end modules have no minimum load requirement and have over-voltage and short-circuit protection, as well as over-current and thermal protection.
According to Behlman President, Ron Storm, “When we introduce the Behlman VPXtraâ„¢1500CS in 2014, we knew we had a winner, because it was the first system of its kind that converted both local three-phase ac and aircraft three-phase ac to the highly regulated dc output needed for mission-critical airborne, shipboard, vehicle and mobile applications. The popularity of the VPXtraâ„¢1500CS quickly lead to requests for a single-phase version that would provide essentially the same performance and benefits. Now, our recently launched VPXtraâ„¢ Reconfiguration Program has made it possible to deliver the Behlman VPXtraâ„¢1500CS3.â€
VPXtraâ„¢1500CS is power factor corrected and can be powered from 3-phase 115/200 Vac, 60Hz utility ground power, 400Hz aircraft power, or 115Vac, 3-phase, Delta shipboard power. The new VPXtraâ„¢1500CS3 is also power factor corrected, and accepts from 85- to 265-Vac, 47-440Hz input, which assures compatibility with standard US or aircraft single-phase power as well as 220-, 230- or 240-Vac Euro power at 50Hz.
