LS9923 Programmable Withstanding Voltage & Insulation Tester

The LS9923 Programmable Withstanding Voltage & Insulation Tester is an integrated 33ing instrument engineered for compliance verification of electrical products. This device combines two essential safety testing functions: AC/DC withstand voltage testing and insulation resistance testing within a single platform.

The instrument precisely evaluates dielectric strength and insulation integrity under high-voltage conditions, supporting compliance testing requirements across multiple sectors including consumer appliances, industrial equipment, and medical devices. The LS9923 incorporates a high-precision voltage sampling module and rapid overcurrent protection circuitry with millisecond-level response time. The output voltage range spans AC/DC 0-5.00KV, providing comprehensive testing capability while preventing irreversible damage to devices under test through immediate fault interruption.

Operational features include remote control rod functionality, audible/visual alarm systems, and programmable test duration control. The user interface is designed for both production line efficiency and laboratory precision, supporting high-volume testing environments while maintaining the accuracy required for research and development applications. This instrument represents an optimal balance of safety, measurement accuracy, and operational efficiency for electrical insulation verification.
