The KDJB-1200Y is a high-performance, six-phase relay protection tester engineered for comprehensive validation of modern protective relays and automation systems. Featuring six independent AC/DC current and voltage sources, ultra-fast switch outputs, and an integrated industrial PC, it supports complex tests—including differential protection, auto-transfer (ATS), distance relays, and transient fault simulations—with lab-grade accuracy in a portable 19 kg field-ready unit.
The KDJB-430A is a lightweight, high-performance relay protection tester that combines advanced power electronics with high-fidelity linear amplifiers in an ultra-compact form factor. Featuring a 10.5-inch HD touchscreen, dual-core DSP processing, and robust AC/DC output capabilities, it delivers laboratory-grade accuracy for on-site testing of protective relays—ideal for field engineers seeking portability without compromise.
