Behlman Electronics’ BL3X100 avionics bench power supply (ABPS) has been selected for integration into the US Army CH-47 Chinook helicopter’s portable avionics test systems.
The integration of the modified commercial off the shelf (COTS) frequency converter in test systems is expected to enable ground crews to update mission-critical software and firmware for the CH-47 Chinook without using the aircraft’s on-board power.

Behlman president Ron Storm said that the army initially started evaluation of the Behlman COTS BL3X350 converter for its Chinook helicopter application.
”When it was discovered that they needed less power and a smaller chassis, plus additional features, we are proud to be able to quickly modify the standard unit and deliver the modified COTS Behlman BL3X100, which gave them everything they needed in a shorter time than they expected,” Storm added.
Representing one of fifty different Behlman COTS and modified COTS frequency converters designed to offer ground and mobile power for multiple military applications, the Behlman BL3X100 provides 115/200 VAC, 3-phase, isolated and floating at 400Hz, plus 28VDC power.
Besides over-temperature and short-circuit protection, the converter also offers voltage fold-back during overloads to ensure supply of undistorted waveforms essential for avionics performance by the power output.
