  • Allows amplifiers without direct constant-voltage capability to be easily integrated into distributed systems
  • "Jumper" cables are provided to easily integrate the XFMR unit with a Com-Tech DriveCore amplifier


  • Output connectors: Pluggable barrier block connectors that accepts up to 14 AWG wire
  • Frequency Response: +/- 1.0 dB (70 Hz to 15 kHz)
  • Insertion (Core) Loss: < 1.0 dB max (70 VAC)
