Voltage regulator, stabilize the voltage, to prevent voltage instability, to achieve power-saving effect, thereby extending the life of electrical appliances. Products installed anti-wave device, to prevent current bumps, protect electrical appliances. Electronic control capacitors, balance current, all-round use of electrical products to improve the use of power, to avoid the waste of electricity. Product itself does not consume current, 24 hours 365 days, all-weather use will not increase the electricity burden. Applicable to air-conditioning, washing machines, refrigerators, fans, television, water pumps, audio, fluorescent and other products. For general family, the company line number, shops, small factories. Plug the generators directly in the main line above any one of the idle socket (wall socket) can be formed in the home circuit back to start saving electricity. After plugging the Saver,do not remove or turn off the power, the longer the product is used, the better result it gets. Applicable to any meter common, as long as the current through the energy can play a role, it can save 20-50% eletricity, the biggest advantage of this product is that it do not need electricity meter. Placed in any of the walls of a wall outlet, 24-48 hours or so the whole family's current will be fully controlled Specification Applicable voltage :90V-240V / 50Hz-60Hz Working temperature: -60-75 degree Effective carrying: 15,000 or 18,000W Size: 11.5 * 6.5 * 4CM Weight: 100g Model:EU/US/UK Specifications: Stabilize the voltage,prevent voltage instability, to achieve power-saving effect, thereby extending the life of electrical appliances.
