Power Consumption LCD Vs CRT Monitor

Power Consumption LCD Vs CRT Monitor – Power Consumption LCD Vs CRT Monitor, By using the clamp ammeters, it is known that the Samsung SyncMaster 900NF CRT monitor uses an electric current of 0.52 A, while the Samsung SyncMaster 171V LCD monitor is only 0.16 A. Power Consumption LCD Vs CRT Monitor

With voltage 220V, the CRT monitor consumes power equal to 0.52 A * 220V = 114W. While the LCD monitor consumes 0.16A * 220V = 35W.

AssuminPower Consumption LCD Vs CRT Monitorg that both monitors are turned on 8 hours / day within 20 days / month. So CRT monitor energy consumption by 114W * 8 * 20 hours = 18.24 kWh. While the LCD monitor energy consumption of 35W * 8 * 20 hours = 5.6 kWh.

With the price of electric energy use by TDL housing category 2 think of it amounted to Rp. 890/kWh, then the CRT monitor will cost RP 18.24 * 890 = Rp. 16.233/month and LCD monitor will cost Rp 5.6 * 890 = Rp. 4984. That is, changing from CRT to LCD monitors can save the cost of Rp. 16 233 – Rp 4984 = Rp. 11.249/month. Power Consumption LCD Vs CRT Monitor

The conclusion? LCD monitors are far more efficient, but for home users, energy-saving LCD monitor compared to CRT monitors do not seem too significant. Except maybe if your electric utility close to the limits allowed, using the LCD monitor can avoid having to upgrade electrical service to a level that is more expensive. In contrast to corporate users who use the monitor in large quantities, replacing CRT monitors to LCD may be a significant savings. Power Consumption LCD Vs CRT Monitor

– TDL = electricity basic tariff
– The example we give is the household tariff in Indonesia
