Industrial 25W-5KW Adjustable Wirewound Rheostat | 1Ω-10KΩ ±5% Ceramic Tube Sliding Resistor | High Power Variable Load for Motor Testing/Heavy Machinery/Power Supply Calibration (RX20-300w-5 OHM)
Brutaic-level power coverage - a wide power band of 25W to 5KW, adaptable to industrial-grade shocks (transient overload capacity up to 8KW/30s), ceramic tube body + winding structure solves the pain point of frequent cement resistor explosions in switching power supply/motor testing
Linear precise regulation revolution - Pure copper sliding contacts achieve a wear resistance life of 100,000 times (measured > three times that of similar carbon brush types), with a continuously adjustable range of 1Ω to 10KΩ covering multiple scenarios such as DC speed regulation, equipment temperature control, and plasma power supply
800℃ over-temperature survival design - fused quartz ceramic tube (UL94 V-0 grade) resistant to thermal shock, surface high-temperature paint layer + forced air-cooling tank design, safe operation in the high-temperature zone of welding machine/electroplating power supply for more than 15 years
Industrial violent environment Certification - Passed MIL-STD-810G shock/dust resistance test (30g impact) & IP54 protection level, suitable for vibrating and high-dust environments in mining machine/ship engine compartments
Second-level modification integrated system - end M10 stainless steel bolts (bearing capacity 300A) + bottom three-hole flange bracket (including anti-seismic rubber pad), supporting the replacement and installation of distribution cabinets/test benches within 10 minutes
