Test & Measurement Applications
DC Power Supplies for Automated Test Equipment
Supply multiple DUT rails, repeat power sequences and integrate DC sources into a test rack. Match channel architecture and control interfaces to the station before selecting individual voltage and current ranges.

Where Do DC Power Supplies Fit in Automated Test Equipment?
DC sources provide the test voltages while the host coordinates output sequences, measurements and pass/fail decisions. Independent channels let a station manage different DUT rails and test positions.
Power paths: supply channels → fixture connections → DUT rails.
Control and data: host ↔ compatible supply interfaces; host ↔ measurement equipment. These communication links are separate from the DUT power wiring.
The host coordinates source settings with measurement and pass/fail logic. Command response, output settling and acquisition timing are separate parts of the test cycle.
What to Consider When Choosing a DC Power Supply for Automated Test Equipment
Channel count and rail power
Independent outputs, voltage/current per rail, combined system power and future fixture capacity.
Automation and timing
Command support, interface type, trigger behavior, setpoint settling and host-side logging.
Rack integration
AC input, airflow, cable routing, fault shutdown and service access.
One larger supply or independent channels?
A shared source is practical when fixtures need the same voltage and can share a fault response. Independent channels are preferable when each DUT needs a different setpoint, separate current limiting or individual shutdown.
Bench instruments or a modular rack?
Bench units make small stations easy to service and reconfigure. A modular system reduces the number of separate instruments in a multi-rail cabinet. Check usable module combinations, total power and channel isolation requirements for the installation.
What determines test throughput?
Include communication latency, output settling, measurement time and fixture handling. A fast command link alone does not establish a short test cycle. Choose supported commands and triggers that fit the controller software.

Frequently Asked Questions
Does an RS485 connector guarantee PLC compatibility?
No. The controller must support the supply command protocol, addressing and serial settings. Select the interface and protocol together.
Can one channel fault stop the whole station?
That depends on the channel design and station shutdown logic. Define whether a fault should isolate one DUT or stop every output, then implement and test that response.
Can I log data directly from the power supply?
Available readback depends on the model and interface. The test controller or acquisition system normally manages timestamps, records and pass/fail results.
