OVERVIEW

8310 amplifiers are 200Vp, low-noise, DC-to-50-kHz switch-mode amplifiers. 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. 1.1 Features Wide Bandwidth and Flexible The 8310 amplifier is capable of reproducing 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 140 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 140 VRMS are available with no changes in configuration.

The 8310 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 8310 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 10 kVA+ output while drawing less than 10 kW of AC mains power.

Configurable: A key to everyday product usability is quick and easy product (re)configuration. The 8300 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
