Ten advantage of programmable power supply
- High precision output adjustment to meet rigorous testing requirements
Parameter controllability:
The voltage/current/power output resolution can reach the level of μ V/mA (such as Keysight N6705C, voltage resolution of 10 μ V, current resolution of 1 μ A);
Support continuous adjustable or step-by-step adjustment (such as 0.1V/0.01A step), accurately simulate battery discharge curves, chip operating voltage fluctuations, and other scenarios.
Scenario: In semiconductor wafer testing, it is necessary to provide a power supply with an accuracy of ± 0.05% for the probe station to ensure the accuracy of IC yield detection.
- Multi mode programmable, simulating complex power environments
Waveform and sequence editing:
Supports free switching between constant voltage (CV), constant current (CC), and constant power (CP) modes, with a dynamic response time of less than 1ms;
Programmable output of any waveform (such as sine wave, square wave, sawtooth wave) or custom sequence (such as voltage linearly rising from 0V to 5V, maintaining for 10 seconds and then jumping to 3.3V).
- Multi channel independent control improves parallel testing efficiency
Channel collaboration capability:
Support independent output of 2-8 channels (such as TETRIX PRX8, 8-channel isolated output), with independent voltage/current settings for each channel;
Channels can be triggered synchronously (with a delay of less than 10 μ s) to achieve synchronous power supply of multiple power rails (such as multi voltage domain testing of motherboard CPU+GPU+memory).
Data: Multi channel power supplies increase the efficiency of automated testing equipment (ATE) by 50% and reduce the wiring complexity of multiple single channel power supplies.
- High speed dynamic response, simulating transient load changes
Transient performance:
Load step response time<50 μ s, overshoot<1% (such as Kikusui PCR series), can simulate transient scenarios such as motor start-up and LED surge current;
Support setting the rising/falling slope (such as setting different slopes of 1ms/10ms/100ms for voltage from 0V to 10V).
Scenario: In communication equipment testing, it is necessary to simulate the instantaneous high-power demand of the 4G base station PA module (such as a sudden increase from 1A to 5A) to verify the dynamic stability of the power supply.
- Remote control and automation integration, suitable for industrial production lines
Interface and Protocol:
Standard USB/RS232/Ethernet/LAN interface, supporting industrial protocols such as SCPI/Modbus;
It can be controlled through LabVIEW, MATLAB, or self-developed software programming (such as one click execution of “voltage 0-30V scan, load current collected every 1V”).
Case: In the lithium battery PACK production line, the programmable power supply is linked with the PLC to automatically perform charge and discharge cycle testing on the module, with a daily processing capacity of over 2000 sets.
