Standard Directional Gyroscopes
4000B-series
-
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

Ultra Slim DIN Rail AC-DC Power Supplies
DPC Series
-
XP Power today announced the DPC series of highly efficient ultra slim DIN rail AC-DC power supplies. Available in 30, 50 and 70 Watt single output models, they all accept the universal input range from 90 to 264 VAC without the need for any input selector switches. Taking up significantly less space on the rail by being up to 44% slimmer than current generation DIN rail power supplies, the 30 Watt DPC30 measures just 90.0 x 100.0 x 22.5 mm (3.6 x 3.94 x 0.89 inches). Also, the 50 Watt DPC50 measures 90.0 x 100.0 x 30.0 mm (3.6 x 3.94 x 1.18 inches) and the 70 Watt DPC70 measures only 90.0 x 100.0 x 40.5 mm (3.6 x 3.95 x 1.59 inches). Offering all the popular nominal output voltages from + 5 to + 48 VDC, the single output can be adjusted up to + 30% of stated nominal, model dependant, in order to accommodate non-standard voltage requirements or to make up for line losses. All models feature a green LED to indicate output on.

Aircraft Escape Systems
-
The Emergency Interseat Sequencing System (EISS) was designed an qualified for the F-15K Fighter and has since been installed in the F-15SG and F-15SA configurations of the F-15. The system consists of Thermal Batteries with Initiators, a Digital Interseat Sequencer, Mode Selector, and customer provided cabling Electro-Explosive Devices (EEDs). The system is operated from either thermal battery and aircraft 28Vdc for redundancy. A separate field Test Set (EESSTS) performs both complete system continuity tests and an operational test of the total system installed in the aircraft. The sequencer is programmable and could be used in any escape system.Based on the initiation point, Forward or Aft Seat Handle, Internal or External Canopy Jettison Handles, and the Mode Selector setting, the Sequencer provides firing pulses to the EEDs to support canopy removal, ejection seat inertial reel activation(s) and ejection seat catapult firing(s). Sensing capabilities are provided to determine system state, canopy gone, seat gone, so as to provide the optimum escape timing.

Autopilot Directional Gyroscopes
4000C/D-series
-
The 4000C/D is an air-driven directional gyro with A.C. autopilot pickoffs. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. Two knobs control the gyro. The left knob is used to cage the unit, and the right knob is used to select the instrument’s heading. To change course, the right selector knob is pressed and turned to disengage the dial shaft and set the pointer to a new heading. Releasing the selector knob re-engages the pointer with the dial shaft. As the aircraft turns onto a new course, the pointer returns to its original position. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).
