OVERVIEW
The 8504 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 8504 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 4 kW of AC mains power.
Configurable: A key to everyday product usability is quick and easy product (re)configuration. The 8500 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: 8504 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.
