AE Techron 8500 Series Switch-mode Amplifiers Introduction Congratulations on your purchase of an 8500 se-ries digital power amplifier. 8500 series amplifiers are 400Vp, low-noise, DC-to-50-kHz switch-mode amplifiers. They are fast enough for DC automo-tive dropout testing and capable of AC voltages required for ISO 61000 and Aviation testing. Plus, they have low enough noise and distortion specifi-cations to be the reference power source in power quality measurements. Features Wide Bandwidth and Flexible The 8500 series amplifier is capable of reproduc-ing AC, DC and AC+DC waveforms into loads from a dead short to high impedance. It 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 cur-rent, for a given voltage, is available for all wave-form 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 driv-ing 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 amplifier is capable of receiving, reprocess-ing and returning to the load up to 5X its rated power. The result is a system capable of up to 120 kVA output while drawing less than 24 kW of AC mains power! Configuration Options A key to everyday product usability is quick and easy product (re)configuration. The 8500 series amplifier 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, coils) Input: Balanced and/or unbalanced Mode: Voltage source or current source Output…
