8600 Series
DC – 50 kHz, 400 Vp Switch-Mode Amplifiers
8600 Series
10 kW to 60 kW (up to 120 kVA), up to 80A continuous, three-phase
AE Techron’s 8600 Series amplifiers are 400Vp, low-noise, DC-to-50 kHz switch-mode amplifiers. The 8600 Series provides a unique combination of the advantages of switch-mode and linear amplifiers. Switch-mode efficiency is combined with a low noise floor and THD, while also benefitting from high slew rates and wide bandwidth. The 8600 Series is also able to safely drive both reactive and resistive loads of varying impedances with no loss in rated output power.
Key Performance Capabilities:
- Bandwidth: DC to 50 kHz
- Voltage: 0 to 260 VRMS; 0 to 400 VDC
- Slew rate: Up to 60 V/µs
- Current: Up to 80 ARMS*
- Distortion: <0.2%
- Power: 10 kW*
- Power levels up to 2X rated power when driving reactive loads
- High power efficiency and density
*Models available with output power from 10 kW to 60 kW (capable of up to 120 kVA).
OVERVIEW
8600 series amplifiers pack a lot of power into a small package. They are able to produce surge power ratings at up to 20kW, and process apparent power at levels up to 2X the continuous power ratings.
This makes an 8600 series amplifier an ideal choice for applications that require wide bandwidth, high power and great value. The 8600 series is also AC and DC capable, useful for producing power with quick surges or drop-outs, like those required for conducted immunity testing of AC or DC power systems found in military, commercial, or general aviation.
Features:
Lower magnitude, higher frequency ripple noises: The reduction in output filter component size also makes it easier to implement more complex, higher-order low-pass filters, to greatly reduce output ripple noise. The 8600 series uses this advantage to create output voltages of up to 400 Vp with 1 MHz ripple noises that are less than 2 Vp, with in-band noise specifications similar to low-noise linear amplifiers. If even lower noise floors are needed, simple, small, external filtering can reduce this noise even further.
Optimized for transient waveforms and reactive loads: The 8600 Series of amplifiers are compact and capable. They are able to drive purely resistive loads, at rated power, continuously, but really excel when it comes to reproducing short-duration waveforms and/or driving reactive loads.
Scalable: The 8600 series is scalable, available in power levels from a 10 kW, 3U, single-phase, bench top model to mini rack systems that can deliver up to 120 kVA of power into reactive loads at currents of up to 480 ARMS.
Configurable:
A key to everyday product usability is quick and easy product (re)configuration. The 8600 series provides all key configuration controls on the back panel 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: Correction to voltage drops to the load

Note: 8610 power ratings shown are for unit configured for 240VAC. At output voltages above 90VAC, units configured for 120VAC mains input may be breaker limited. Contact AE Techron for 120VAC performance ratings. Performance data is for a purely resistive load; performance will be improved into loads that are partially or completely reactive.
