The HWTB-V037UN-CE is a 3300W comprehensive protection platform integrating a universal interface, real-time digital display, and high-precision adjustment. It is designed to provide ultimate customized protection for core home appliances in globally variable power grid environments.

This product grants users a high degree of control, with startup time precisely set between 5-999 seconds. For 230V power grids, both its overvoltage (230V-280V) and undervoltage (150V-210V) protection thresholds support digital fine-tuning. Internally, it features a high-performance microprocessor and thickened copper conductive strips. An optional 125J surge protection scheme, combined with precise 50/60Hz locking, ensures absolutely stable output voltage.

It is primarily suitable for protecting televisions, printers, computers, refrigerators, and air conditioners. The digital display not only facilitates parameter calibration but also provides real-time alerts for power anomalies. Its universal socket design eliminates geographical limitations.

Safety and performance specifications: Flame retardant V0 and pure copper conductor
