• Replaced by: 8622
• USB to TTL serial converter cable, RS232 to TTL serial converter cable and application software included
• All models are rack mountable. Compact 300 W and 600 W models for bench use
• Over-Current/Over-Voltage/Over-Power/Over- Temperature Protection
• Constant current (CC), resistance (CR), voltage (CV) and power (CP) operation
• Bright, easy to read display (VFD technology)
• List mode operation for increased throughput.
• Built-in transient generator
• Store 25 instrument setups
• Selected models operate up to 500 V, suitable for high voltage applications
• Remote voltage sensing to compensate for the effect of voltage drop in wires.
• Flexible triggering: Create trigger events by front panel keystroke, back panel TTL signal, or software.
• Short circuit test
• Low minimum operating voltage of < 0.1 V and minimum input resistance of 5 mΩ (model 8518) allowing the load to sink high current at low voltages, required for fuel and solar cell applications
• Built-in high resolution (0.1 mA/1 mV) voltage and current measurement (models 8500 & 8502)
• Battery testing mode to provide A*hr rating of battery (ending voltage level is adjustable)
• Thermostatically-controlled fans allow operation in quiet environments with minimal disruption.
• Wide voltage and current range, 0 to 500 V, 0 to 240 A (5000 W max)

Applications:

• High voltage applications
• DC power supply testing
• Characterization of rechargeable batteries. A battery test mode is provided that will measure the ampere*hour (A*hr) characteristic of a battery.
• Fuel and solar cell test
