T 2000: Two-to-One Step-Down, Up to 200W Audio Power

T 2000 Transformer

T 2000

Low-Frequency Conducted Susceptibility Transformer

  • For testing to DO 160 Section 16 and 18 standard
  • Optimized for use with AE Techron 7220 Series amplifiers
  • Protected from over-current by a thermal breaker on the primary and a 35 ARMS breaker on the secondary
  • Durable steel and high-density polyethylene case for impact resistance

Key Performance Capabilities:

  • Frequency response: 10 Hz to 250 kHz
  • Up to 200W audio power
  • Up to 40 Ap AC or DC secondary current
  • Two-to-one step-down
  • Output via Multi Contact 100A plugs; mating connectors included

The T2000 Audio-Bandwidth Conducted Susceptibility Transformer was designed to meet or exceed the LF conducted susceptibility test requirements of DO 160 Section 18. The T2000 is used to apply the required test signals to the lines under test for ripple voltage tests and continuous or transient conducted immunity tests. It may also be used as a 2-to-1 step-down transformer. The secondary can support up to 40AP.

The T2000 transformer supports up to 200W and is able to pass up to 40AP on the secondary. The turns ratio provides a 2-to-1 step down.

The T2000 provides convenient input connectors via binding posts. Standard 0.75-inch spacing of binding posts allows use of standard plugs. Output is via Multi Contact 125A plugs.

A thermal breaker protects the unit against over-current conditions on the primary. A 35 ARMS breaker protects the unit against over-current conditions on the secondary. A rugged, impact-resistant case and robust design protects the transformer from accidental damage.

The T2000 transformer is for use by experienced staff.
