DC Electronic Loads

8500 Series

2

Features

I

Constant current (CC), resistance (CR), voltage

(CV) and power (CP) operation

I

Wide voltage and current range, 0 to 500 V, 0

to 240 A (5000 W max)

I

Low minimum operating voltage of < 0.1 V

and minimum input resistance of 5 m

Ω(model

8518) allowing the load to sink high current at

low voltages, required for fuel and solar cell

applications

I

Selected models operate up to 500 V, suitable

for high voltage applications

I

Built-in transient generator

I

Short circuit test

I

Built-in high resolution (0.1 mA/1 mV) voltage

and current measurement (models 8500 &

8502)

I

Bright, easy to read display (VFD technology)

I

Over-Current/Over-Voltage/Over-Power/Over-

Temperature Protection

I

USB to TTL serial converter cables and

application software included

I

List mode operation for increased throughput.

I

Battery testing mode to provide A*hr rating

of battery (ending voltage level is adjustable)

I

Flexible triggering: Create trigger events by

front panel keystroke, back panel TTL signal,

or software

I

Remote voltage sensing to compensate for the

effect of voltage drop in wires.

I

Store 25 instrument setups

I

Thermostatically-controlled fans allow

operation in quiet environments with minimal

disruption

I

All models are rack mountable. Compact 300

W and 600 W models for bench use

Applications:

I

DC power supply testing

I

Characterization of rechargeable batteries. A

battery test mode is provided that will measure

the ampere*hour (A*hr) characteristic of a

battery

I

Fuel and solar cell test

I

High voltage applications

Low voltage operation

The 8500 series can operate well below 1 V

which is important for low voltage application

such as fuel cell and solar cell testing. All models

can regulate (provide a stable input) down to

0.1 V. Model 8518, due to its particularly low

input resistance, can operate at full scale current

of 240 A at 1.2 V (see image)
