• AC Phase Current Output: 0–40 A, max 450 VA; 3-phase parallel: 0–120 A, max 900 VA • DC Current Output: 0–±10 A/phase, 0–±30 A/3-phase • AC Phase Voltage Output: 0–120 V, line voltage: 0–240 V, max 100 VA • DC Voltage Output: 0–±160 V/phase, 0–±320 V/line, max 140 VA • Frequency Range: 20–1000 Hz, Harmonics: 1–20 • Digital I/O: 10 channels input, 8 channels output, timing 0.1–9999 ms, accuracy <0.1 ms • Dimensions/Weight: standard industrial chassis, integrated cooling and protection HZJB-I 3 Phase Relay Protection Tester integrates a digital signal processor, high-precision D/A conversion, and linear voltage/current amplifiers to simulate complex waveforms including harmonics, transients, and short-circuit conditions. The built-in industrial control computer with 6.4" TFT LCD, tracking ball, and front-panel keyboard allows full operation without external peripherals, while USB, Ethernet, and serial ports support data access, communication, and software upgrades. Designed for laboratories, substations, and field testing, the tester provides precise measurement and reliable waveform output with protections against overcurrent, overvoltage, short circuits, and overheating. Auxiliary DC outputs (110/220 V) supply external devices. Compact, user-friendly, and versatile, it supports AC/DC testing of currents and voltages for power equipment, protective relays, and switchgear, enabling efficient evaluation, commissioning, and maintenance.
