electrical ceramic heater 1.Product instruction: it heats inside, and its thickness is 1.2mm 2.It can hoist temperature rapidly, especially, when it is used, it can renew the temperature in 7 seconds after hair is straightened. But the PTC heater needs 2-3 minutes to renew temperature. 3.Because the inside resistance can be adjusted, the temperature can be adjusted, but PTC can’t do it; the ceramic heater is safe and ideal for applying to top-grade hair straighteners, liquid crystal hair straighteners and digital straighteners. 4.The temperature can be hoisted to 200 oC in seconds and 500 oC in 30 seconds, the max and steady temperature can be up to 600 oC-800oC 5.Electricity: 70x15 200V, 150Ω 2.47-2.5A 6.Voltage: 55V, 110V, 220V it can bear high voltage of 5000V 7.Ceramic heater pass 30 minutes ’On’, 30 minutes ’off’ for 1000 cycles life test. 8.Specification of Ceramic Heater: Length x Width, Resistance, Voltage a.70±3% mm x 7±0.2mm, 30Ω~180Ω, 110 Vac.~220Vac. b.70±3% mm x 10±0.5mm, 30Ω~180Ω, 110 Vac.~220Vac. c.70±3% mm x 15±0.5mm , 30Ω~180Ω, 110 Vac.~220Vac. d.70±3% mm x 20±0.5mm, 30Ω~180Ω, 110 Vac.~220Vac. e.70±3% mm x 30±0.5mm, 30Ω~180Ω, 110 Vac.~220Vac.
