Programmable DC electronic rheostats up to 5000 Watts

B&K Precision has added eight additional models to its line of programmable DC electronic loads. The 8500 family of programmable DC electronic loads are suitable for characterizing and testing DC power supplies, DC-DC converters, batteries, fuel cells, and photovoltaic solar cells.

The electrical ratings of 8500 series are, power ratings of 300 W to 5000 W, current ratings of 30 A to 240 A, and the voltage rating of 60 V to 500 V.

The 8500 series DC elctronics loads (rheostats) can operate in CC, CV, CR or CP mode while voltage/current or resistance/power values are measured and displayed in real time. The load terminals are isolated and floating. Extensive protection, including over temperature, over power, over voltage, over current and reverse polarity will help protect your valuable prototype. All parameters can be set quickly and precisely from the front panel, or programmed via RS232 (included) or USB (optional) interfaces.

Other features of the 8500 series programmable DC electronic loads include:

1. Low minimum operating voltage of < 0.1 V and low input resistance (model 8518) allows the load to sink high current at low voltages, required for fuel and PV solar cell applications design.
2. Built-in transient generator
3. Built-in high resolution (0.1 mA/1 mV) voltage and current measurement (models 8500 & 8502)
4. Bright, easy to read display (VFD technology)
5. Over-Current/Over-Voltage/Over-Power/Over-Temperature Protection
6. RS232 to TTL serial converter cable and application software included
7. List mode operation for increased throughput.
8. Battery testing mode to provide Ah rating of battery (ending voltage level is adjustable)
9. Flexible triggering: Create trigger events by front panel keystroke, back panel TTL signal, or software.
10. Remote voltage sensing to compensate for the effect of voltage drop in wires.
11. Thermostatically-controlled fans allow operation in quiet environments with minimal disruption.

Price: 8500 Series Programmable DC Electronic Loads starts from US$1050.
