Feature:1. With a peak voltage absorption circuit, it can effectively protect the high‑power SCR anti‑surge, anti‑spike, RC absorption multiple protection.2. Imported chip SCR, all‑aluminum heat sink, high temperature circuit board.3. Built‑in accurate resistance, high voltage capacitor, stable output, no lag and no delay.4. Flame-retardant metal casing, high-temperature flame-retardant without deformation, metal spray paint does not rust, effectively prevent high temperatures, prevent heavy pressure, and eliminate potential safety hazards.5. Self‑developed button control panel with gear display and output power button to support one‑key cut off output.6. Independent switch control, free control of power input, cut off output, mounting hole design, humanized design, flat, easy to hang.7. Use multifunctional industrial sockets, thicker internal copper parts, large current, good contact and safety.Specification:Material: Aluminum alloy, thyristor, PCB, copper, cold rolled steelLimit Power: 2500W (adapt to 1800W-2000W resistive load)Rated Current: 9ALimit Current: 15APower Switch: YesSCR Model: STMicroelectronics, SCR, BTA41-600B/800B.Package List:1 x Voltage RegulatorNote:1. When the machine is empty, the measured output voltage is a virtual voltage, and a load above 20W must be connected to measure the correct output voltage2. When inputting AC power, the output is also AC, not DC.3. The 4000w mentioned above refers to the limit power when working in a resistive load. The inductive load is 1/3 of the resistive load. The resistive load refers to the tungsten filament lamp, heating wire, etc., and the inductive load refers to the series motor. And so on, there are circuit board electronic products used with caution.4. The metal shell of this product must be safely grounded.
