8500 Series

The First Wide-Bandwidth,
High-Power Digital Amplifiers

AE Techron’s 8500 Series amplifiers are the first wide-bandwidth, high-power digital amplifiers available from any manufacturer. They are fast enough for DC automotive dropout testing and capable of AC voltages required for ISO 61000 and Aviation testing. Plus, they have low enough noise and distortion specifications to be the reference power source in power quality measurements.

Key Performance Capabilities:

  • Bandwidth: DC to 50 kHz
  • Voltage: 0 to 250 VRMS; 0 to 350 VDC
  • Current: 100 to 500 ARMS
  • Distortion: 0.1%
  • Power: 4 kW to 20 kW*
  • Power levels up to 5X rated power when driving reactive loads
  • High power efficiency and density

*Models available with output from 4 kW to 20 kW (capable of up to 125 kVA).

Wide Bandwidth and Flexible
The 8500 Series of amplifiers are capable of reproducing AC, DC and AC+DC waveforms into loads from a dead short to high impedance. They can be used to simulate a battery at 13.5 VDC or be an AC source with a L-N potential of up to 250 VAC. Rated current, for a given voltage, is available for all waveform types (AC, DC or AC+DC) at frequencies from DC to 50 kHz. Voltages from 0 to 250 VRMS are available with no changes in configuration.

Reuses Energy from Reactive Loads
The 8500 Series excels when it comes to driving reactive loads. As frequencies increase, the effective-impedance of the load becomes a much larger part of the total load to be driven (especially with inductive loads like coils). However, when driving reactive loads, the 8500 Series is capable of receiving, reprocessing and returning to the load up to 5X its rated power. The result is a bench top system capable of 20 kVA+ output while drawing less than 4 kW of AC mains power!

Scalable
The 8500 Series is scalable, available in sizes from a 3U, single-phase, bench top model to mini rack systems that can deliver up to 125 kVA of power into reactive loads at currents of up to 500 ARMS.

Configurable
A key to everyday product usability is quick and easy product (re)configuration. The 8500 Series provides all key configuration controls on either the front or back panels of the unit. Configuration options available include:

  • GAIN: Fixed or variable gain (0 to 40)
  • CURRENT LIMIT: From 5% to rated limit (to protect fragile DUTs or where specified in the Standard)
  • DC CONTROL: DC enabled or DC blocked and DC Servo (for driving transformer-coupled loads or coils)
  • INPUT: Balanced and/or unbalanced
  • MODE: Voltage source or current source
  • OUTPUT IMPEDANCE: Variable from 0 to 1 ohm (Voltage mode)
  • SENSE: Sense line with correction of up to 4 volts
