Adopt multi functional industrial sockets, thicken copper part design, with fine contact and safety. Humanized installation hole design, keep flat place or hanging on it is decided by yourself. Silent work, energy saving, stable anti-noise, and with wide range of use. Suitable for electrical components, such as: electric stove, water heater, heat transfer lamp dimming, small motor, electric soldering temperature and etc.. Notes: When measuring the output voltage when it is empty, it is a virtual voltage. It must be connected to a load of 20W or more to measure the correct output voltage. Input AC power, the output is also AC, not DC. The above mentioned 4000W refers to the ulti mate power when working under resistive load. The inductive load is 1/3 of the resistive load. The resistive load means that the inductive load such as a tungsten filament lamp or a heating wire is a series-excited motor, etc., and the circuit board electronic products are used with caution. This product is a metal case and must be grounded safely. Specifications: Name: SCR Voltage Regulator Model: NHT-4000W Material: aluminum Color: black Input voltage: AC 220 V Output voltage: 0-220 V Max power: 4000W Voltage adjusting range: 0-220 V Rated current: 9A Max current: 18A Main machine size: 115 * 100 * 83mm / 4.53 * 3.94 * 3.27in Item weight: 459g / 1.01lb Package size: 180 * 100 * 115mm / 7.09 * 3.94 * 4.53in Package weight: 522g / 1.15lb Package list: 1 * SCR Voltage Regulator 5000W The thyristor electronic voltage regulator is mainly used for resistive loads (incendescent filament, incandescent lamps,etc.), monophase A-C brushless motor, adjustable pressure range from 20Volt-220Volt, suitable for low voltage drive heaying wire. Factory use: such as cuttings tyrofoam, pearl cotton, raincoats, make it to adjust the voltage, reduce power and so on. With the bi-direcyional high-power thyristor, the current is up to 40amps, which solves the over-current problem caused by the electric resistance of the electric furnace wire when coolingis too small; it can easily adjust the output voltage of the mains at 10Volt-continuously adjustable between 220Volt, 0 delay, 0 hysteresis. Use case: Heat regulation of electric stoves and water heater, dimming of lamp and lantern, small motor speed adjustment, electric iron thermostat and so on. Features: LED digital display, clear and convenient to view the data. High accurate potentiometer is used for voltage regulation, real time voltage regulation is under control. High temperature retardant without deformation, metal material, rust-proof, effectively prevents high temperature and oxidation and rust. 0 lag, 0 delay, with peakvoltage absorption circuit effectively protect high power Thyristor antisurge, antipeak, RCabsorption multiple protections. With side holes for quick heat dissipation. Safer in use.
