OVERVIEW

The Adaptive Power 4 Series of Programmable DC Electronic Load Modules are ideally suited for testing multiple output AC/DC power supplies, DC/DC converters, battery chargers, LEDlighting power supplies and other power products.

The high power density of the 4 Series allows up to 8 loads to be installed in a single 19″ wide rack-mount mainframe. For lesser demands, mainframes with two slots or a single slot are available as well.

The 4 Series consists of a total of 12 different modules types providing a wide variation of possible voltage, current, power and feature choices. Starting at 75 Watt and ranging to 300 Watt per module, all modules offer dual range capability for optimal accuracy and resolution. Voltage ranges start at 60Vdc and extend up to 500Vdc. Special LED simulation loads are available for lighting applications up to 500Vdc. (41D/42D Models)
Note: For voltage requirements up to 600Vdc on 4 Series loads, contact factory for special quote.

APPLICATIONS

Load Versatility

All ASP 4 Series Loads are equipped with a powerful microcontroller and user friendly controls to provide capabilities that cover a wide range of load applications. Built in metering of Voltage, Current, Power and Resistance.

Power Supply Testing

With a range of up to 8 load channels, the 42L load modules support testing for multiple output power supplies and AC/DC converters. The ability to load all outputs simultaneously of to test up to eight single output DC supplies at once provides significant test throughput in high voltage production environments.

Power Supply Design

With built-in features like over current protection (OPC) test and over power protection (OPP) test and dynamic constant current waveform testing, new power supply designs can be thoroughly evaluated against design specifications. An analog input mode allows arbitrary current waveforms to be applied to a unit under test as well.

Battery Charge/Discharge Testing

Time sequencing of specific discharge current levels as a function of battery voltage allows characterization and performance testing of various battery chemistries. The high current resolution and accuracy of the 4 Series load modules supports testing of very small batteries for portable device applications.

LED Lighting

The 41D and 42D load modules are specially designed to support LED lighting applications by allowing accuracy simulation of LED load characteristic to be simulated. These modules simulate an LED V-I curve based on Vd and Rd input settings. For dimming LED supply development and test, the 41D and 42D modules include a PWM dimming output signal with programmable duty cycle and frequency. Recently updated with higher current support levels, multiple voltage ranges for higher accuracy and resolution, the 41D/42D LED loads offer the best price performance for lighting applications available.
