BBG-SBA2 Serial to Synchro/Resolver Booster Amplifiers

The Synchro Booster Amplifier (SBA) is a stand-alone system, which provides amplification of synchro signals.

The SBA series of amplifiers are designed to be conduction cooled by mounting directly to the chassis and is factory configurable to customer requirements for easy field installation. Models available include 6.81V resolver, 11.8V and 90V synchro at both 60 and 400 Hertz.

Applications

  • Radar Systems (antenna azimuth)
  • Navigation Systems (gyrocompass, speedlog, course, pitch, and roll)
  • Industrial Processes (position, velocity)
  • Meteorology Instruments (wind speed and direction)

Card Layout:

The BBG-SBA operates on 115 Volt, 60 Hz or 400 Hz AC reference power to convert low power synchro or resolver inputs into high power synchro outputs. Due to the pulsating power supply, the device operates more efficiently allowing for smaller size. The SBA is current limited and voltage protected against reference and load short circuits and transients. Thermal protection is provided for temperatures in excess of +125 °C. In addition, the SBA provides Enable, BIT and Kick circuitry for added control and protection.

Features:

  • 6.81Vrms Resolver
  • 11.8 or 90 Vrms Synchro
  • High Efficiency
  • 6VA Output
  • Short Circuit and Transient Protected
  • Temperature Protected
  • Enable, BIT and Kick Circuitry
