6000W SCR Digital Voltage Regulator Speed Control Dimmer Thermostat AC 220V 1. This item has a new bi-directional large power silicone controlled rectifier, and the current can be up to 80A, which is a good solution for the over current of electric stove wire caused by low resistance when cooling 2. It can easily regulate the output voltage on a 0-scale (non-linear) to power the electrical appliance 3. Designed with a large and thick heat sink which would improve heat dissipation 4. This voltage regulator is adjustable by button which is much more stable than Potentiometer 5. The voltage regulator has a wave voltage absorption circuit and effectively protects the large power silicone controlled rectifier, longer life and more durable Specification: Features: This item has a new bidirectional large power silicone controlled rectifier, and the current can be up to 80A, which is a good solution for overcurrent of electric stove wire caused by low resistance during cooling. It can easily adjust the output voltage on a 0-scale (non-linear) to power the electrical appliance. Designed with a large and thick heatsink that would improve heat dissipation. This voltage regulator is adjusted by button, which is much more stable than potentiometer. The voltage regulator has a wave voltage absorbing circuit and effectively protects the large silicone controlled rectifier energy, longer service life and more durable. Can be used as a power supply for large electrical appliances, sufficient for household appliances or for a small factory. It can be widely used as heat controller on electric furnaces, water heaters, light dimmer on lamps, speed controller on small motors or temperature controller on electric soldering iron etc. Specification: Voltage: AC 220V Maximum power: 6000W (instantaneous limit power for resistive load; For long time use, 3000w or less is recommended) Voltage regulation: 0- (non-linear) Controller size: 9.7 * 5.7 * 4.2cm / 3.8 * 2.2 * 1.7in Panel size: 7.5 * 6 * 1.7cm / 3 * 2.4 * 0, 7in Panel Screw Hole Spacing: 6*4.5cm / 2.4*1.8in Cable Length: 28.7cm / 11.3in Weight: 190g / 6.7oz (Approx.) Package List oacute;w: 1 x SCR Controller 1 x ABS panel 1 x cable Note: 1, AC input, AC output, the output voltage is lower than (or equal to) the input voltage; The voltage can only be adjusted when connected to the load; Mainly used for resistive loads (e.g. heating cable, electric bulb). 2, it cannot replace electric battery charger, nor drive electrical appliances that use switch power supply (such as 110V TV, speaker, refrigerator, air conditioner, rice cooker with computer), and cannot drive induction cooker, energy-saving lamp . 3. Please note that the new type and old type of this product will be shipped randomly, and please make sure you don't mind before ordering.
