The problem

Heating elements fail in the field after a year; third-party 3000h life tests cost tens of thousands and take two months per batch. The NL-FRG-5 runs the full 3000h cycle in your own workshop.

Capability

5 independently controlled stations, 5000W per station; life cycle power-on 1h + cooling 0.5h (free setting), up to 3000h cumulative; run/stop time 999min settable, 99990 cycles settable, auto stop; test voltage AC0-300V (30kW regulator), 0.5-class V/A meters (0-20A); per-station power meter, over-current alarm; single-station fault stops only that station and records data; water temperature monitored, auto water change over setpoint; 304 stainless tank (1.5mm) with auto refill/overflow/drain; data retained through power failure; over-temp/leakage/over-current protections; Mitsubishi FX3U-32MR PLC.

Standards

GB 4706.1《家用和类似用途电器的安全 通用要求》；GB 4706.12 储水式电热水器特殊要求相关条款；电热元件寿命试验通用工况（通电-冷却循环法）
