DC ELECTRONIC LOADS

4700 SERIES HIGH-POWER, HIGH-CURRENT LOAD

• 6 kW / 120 V / 1200 A in a 10½-inch chassis
• Field parallelable to 36 kW
• Full current at 1 V and operation down to 0.15 V

APPLICATION

The 4700 Series Electronic Loads are intended for testing applications that require a high-current / high-power load with precision internal measurement capability, exceptional reliability, combined with the inherent simplicity and safety of air cooling. The Load is controlled through a PC soft-panel or within an automatic test station such as the 5600 Series Power Supply Tester. Typical power conversion products to be tested include higher-power DC supplies, telecom rectifiers, fuel cells and batteries.

PARALLELABLE FOR HIGHER POWER & CURRENT

To meet higher power/current applications, a single "master" load can be paralleled and synchronized with up to five "slave" loads for a total capability of up to 36 kVA. Special circuitry assures no single load will reach its over-power limits ahead of others. This built-in versatility assures the test engineer need only buy what is required today, knowing that should more power be needed in the future, additional loads can be added with no special modifications.

PRECISION INTERNAL MEASUREMENTS

The 4700 Load is designed to eliminate the need for separate external instruments to make precision measurements. With an internal measurement system equivalent to a 5½-digit DMM, high accuracy measurements of voltage, current and power are provided. Additional benefits of the built-in measurement capability are faster testing speeds and the cost savings from a more streamlined tester architecture.

LOW VOLTAGE OPERATION

To meet the low voltage testing requirements of newer power subsystems, certain batteries and fuel cells, the 4700 Load delivers full-current capability down to 1 V. Even lower voltage operation down to 0.15 V can be achieved at linearly reduced current levels.
