I product features Using unique pulse phase modulation method eliminate tubes acoustic oscillation to ensure the safety of tubes, prolong services life. Adopt unique pulse deduct technology to achieve overload protection. Its consumption is low, the efficiency is as high as 96%; the power factor above 0.99, low total harmonic current distortion, less impact on power network. Wide working voltage range: ac 90v~260v, which can guarantee the output power constant when the input power voltage is unstable. Perfect protection function, such as built-in overvoltage, undervoltage, output short circuit, open circuit, which can protect automatically for safe use. Low temperature rise, it is suitable for wide range environment temperature: -30? to +50?(-22~+122f) Ii technical parameters Lamp watts: 70w high pressure sodium lamp Input voltage frequency: 50/60hz Input voltage range: 160-260v ac Input current: 0.35a Power factor: >0.99 Total harmonic current distortion: =8% Short circuit protection yes Open circuit protection yes Overheating protection yes Lamp failure protection yes Temperature range : - 30 ? ~ + 50 ?
