Chroma 19021-4: 4-Channel Hipot Tester for AC/DC Testing

Chroma 19021-4 – Multi-channel Hipot Tester (AC6kV/8mA, 4ch).

The Chroma 19021-4 Multi-channel Hipot Tester (AC6kV/8mA, 4ch) is engineered for comprehensive electrical safety compliance, offering triple-function capabilities: AC withstand voltage (ACWV), DC withstand voltage (DCWV), and insulation resistance (IR) testing in a compact and powerful 4-channel unit. It is ideal for automated manufacturing lines, component testing labs, and industrial environments requiring rigorous dielectric integrity validation.

The 19021-4 supports Master/Slave control of up to 10 units, making it an efficient solution for scalable and high-volume applications. Each channel operates independently or synchronously, enabling simultaneous multi-point testing. The system features Open/Short Check (OSC), Flashover Detection, programmable voltage and current limits, and safety lockout to ensure reliable and secure operation.

With a test voltage range up to 6kV AC and insulation resistance measurement capabilities reaching up to 50 GΩ, this hipot tester meets the stringent requirements for high-voltage testing. It’s especially suitable for users looking to extend or complement their Electrical Test Instruments suite with a reliable and precise Hipot Tester.
