DC Voltage Dips and Interruptions Generator
Leave a Message
CSS61000-29 DC Voltage Dips and Interruptions Generator is a high-precision intelligent instrument engineered specifically for electromagnetic compatibility (EMC) immunity testing of DC power supply equipment. This instrument simulates common voltage anomalies at DC power supply ports including instantaneous voltage dips, short interruptions, sustained voltage rises, and voltage fluctuations.
The CSS61000-29 features a large English/Chinese Android touchscreen interface and incorporates built-in IEC standard testing protocols. The system supports one-click access to preset testing parameters while allowing comprehensive customization of voltage dip amplitude, duration, and cycle count to accommodate diverse testing requirements.
