T 3700: 1-to-37 Step-Up, Up to 3700 VRMS

T 3700

Electric Field Susceptibility Transformer

  • For testing to DO 160 Section 19 and Boeing D6-16050-5 Section 7.2 standards
  • Optimized for use with AE Techron 7220 Series amplifiers
  • Current-protected input
  • Durable steel and high-density polyethylene case for impact resistance

Key Performance Capabilities:

  • Up to 3700VRMS
  • Robust design: withstand tested to 5,000 VDC
  • 1-to-37 step-up
  • Frequency range: 250 Hz to 35 kHz
  • Output via LGH high-voltage connector

The T 3700 Electric-Field Susceptibility Transformer was designed to meet or exceed the voltage requirements of DO 160 Section 19 and Boeing D6-16050 Section 7.2 testing. It may also be used as a 1-to-37 step-up transformer for voltages up to 3700 VRMS.

The T 3700 transformer is able to generate up to a 3700 VRMS potential. It is withstand tested to 135% of rated output to ensure a long, trouble-free life. The turns ratio provides a 1-to-37 step up to the secondary winding.

The T 3700 provides convenient input connectors via touch-proof, four-way binding posts. Standard 0.75-inch spacing of binding posts allows use of standard plugs.

A 1-amp fuse protects the unit against over-current conditions. A rugged, impact-resistant case and robust design protects the transformer from accidental damage.

The T 3700's voltage output meets or exceeds the requirements of DO 160 Section 19 and Boeing D6-16050-5 Section 7.2. It is for use by experienced staff.
