Ride-Through Validation at 400 VDC

High-voltage telecom and datacom equipment designed for universal input power must operate reliably across a wide range of steady-state conditions and transient disturbances on the input bus. Standards such as ETSI 300-132-3 define these requirements, including the ability to withstand events such as voltage dropouts of up to 20 milliseconds, along with other transient deviations. These conditions reflect real-world scenarios where power interruptions, switching events, and system dynamics can impact input stability.

To verify robust performance, engineers must emulate these disturbances in a controlled and repeatable manner while monitoring current, voltage, and power behavior. This requires programmable power sources capable of generating high-voltage DC conditions and transient events with precision. Accurate validation under these scenarios ensures equipment resilience, compliance with industry standards, and reliable operation in demanding deployment environments.

High-Voltage Dropout Test Solution

Validating high-voltage DC equipment under transient and steady-state conditions requires power supplies capable of precise control, high voltage output, and reliable measurement. The Keysight Advanced ATE system power supply delivers up to 600 VDC with high power density, enabling accurate emulation of 400 VDC telecom and datacom power environments. With programmable control, built-in protection features, and flexible interfaces, this solution allows engineers to generate repeatable dropout and recovery conditions while measuring power consumption and efficiency. Together, these capabilities support comprehensive validation of high-voltage DC systems in development and test workflows.
