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.
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.
