Energy-saving IT devices become the "trend" this summer

As continuous heat waves have significantly increased power consumption recently, many people are trembling with fear over the "electricity bill explosion" of progressive rates. In this sweltering heat where continuous use of air conditioning and fans is inevitable, many people are increasingly refraining from using IT products that consume large amounts of power.

Naturally, interest in energy-saving IT devices is rising. Products with high energy efficiency and features that help reduce power consumption are receiving significant attention, freeing users from the fear of progressive rates.

In particular, smart energy-saving products are establishing themselves as a trend across the entire IT field, from home appliances to portable mobile IT devices carried daily and peripherals. What are the products that prevent power waste and maximize energy efficiency through various energy-saving functions?

Brother Printer Multifunction Device applies "Low Energy Standby" technology to reduce standby power

Printers and multifunction devices, which are essential items in homes and offices, are typical office equipment that is not actually used for very long periods. Therefore, while power consumption during operation is important, it is crucial to consider how much standby power a product reduces. Printers consume 430W during operation and 65W in standby mode, which is relatively high standby power compared to audio equipment (400W, 9W), microwave ovens (1100W, 5W), computers (70W, 50W), and set-top boxes (85W, 30W).

Accordingly, Brother International Korea Co., Ltd. (www.brother-korea.com, hereinafter Brother), a global printer/multifunction device specialist, applies "Low Energy Standby" technology to its products, which reduces power consumption to less than 1W when the device is not in use while the plug remains connected, minimizing standby power costs and implementing eco-friendly operation. This technology can reduce standby power consumption to nearly zero levels.

Brother's color laser printers "HL-L8350CDW" and "HL-L8250CDN" are products that provide high work efficiency even in complex business environments with fast print speeds for quick task processing, networking management and mobile printing support that add flexibility to work. These products incorporate Brother's energy-saving technology "Low Energy Standby," reducing power consumption to 0.04W when powered off (with the plug still connected), enabling cost savings.

Additionally, the "Low Energy Standby" technology is also applied to the A3 multifunction device "MFC-J2320 InkBenefit." The "Low Energy Standby" technology delivers power through a supply board to the main board when the power is on, but when the power is off, it delivers power through a highly efficient low-power supply board, minimizing standby power consumption. Through this, it maintains a state ready for 24-hour printing with only extremely low power consumption of 0.02W.

This device supports fast speeds of up to 35ppm for both black and white/color printing in multifunction high-speed mode, and 27ppm for color, allowing many printing tasks to be completed in a short time. Additionally, it can print up to 2,400 pages in black and white and 1,200 pages in color, and with color ink save mode applied, the three color inks can be individually replaced according to consumption status, reducing unnecessary consumable replacement costs.

LG Electronics UHD TV achieves Korea's first energy efficiency grade 1 rating

LG Electronics' six UHD TV models (65•55•49•43UF6800, 49•43UF6400) have garnered attention as the first UHD TVs launched in the domestic market to achieve energy efficiency grade 1 rating from the Korea Energy Agency.

LG Ultra HD TV comes in two series with six models (model names: 65/55/49/43UF6800, 49/43UF6400) with consumption efficiency ratings from the Korea Energy Agency corresponding to grade 1, showing 60 or below.


These products significantly reduced power consumption by applying panels with RGBW technology. The RGBW panel adds W (White) to the existing pixel arrangement where three sub-pixels of R (Red), G (Green), and B (Blue) are repeatedly placed, arranging sub-pixels continuously in RGBW order.

Since W (White) pixels are placed periodically, light transmittance increases. The RGBW panel can improve brightness by approximately 50% and reduce power consumption by approximately 35% compared to conventional LCD panels of the same size and resolution.

Additionally, LG Ultra HD TV features APL Dimming (Average Picture Level Dimming) function that analyzes the brightness of received video signals, lowering screen brightness when viewing dark images and raising brightness for bright images. This function increases contrast ratio while reducing power consumption.

Sarotech Large-capacity RAID Storage with energy-saving functions

Sarotech (CEO Park Sang-in, www.sarotech.com), a storage specialist, presents two models from the "PRORAID" series of intelligent large-capacity RAID storage equipped with smart panels: "PRORAID 2-bay (model name: PRORAID-20US6G)" and "PRORAID 4-bay (model name: PRORAID-40US3)"

The PRORAID series is linked with PC power and automatically shuts off when the PC is turned off, providing high energy-saving effectiveness. Also, various functions can be checked and configured directly through the Multi-Function LED display, a smart panel on the device front, and various RAID modes can be controlled with a single button. It features forced air circulation (built-in fan) to effectively expel heat outside the product and a smart fan that adjusts fan speed according to internal temperature, and supports hot-swap function for easy replacement with new hard drives.

Vornado launches ultra-energy-saving air circulator with 80% reduced power consumption

In summer, "air circulator" products are gaining popularity. When used together with air conditioning during summer, they provide excellent cooling effects, reducing electricity bills, and can be used like fans, attracting attention as energy-saving appliances.

Air circulators resemble fans but function differently. Fans spread air in nearby distances, while air circulators discharge straight vortex winds beyond 20 meters. They circulate stagnant indoor air and maintain uniform indoor temperature. When an air conditioner and air circulator are used together, you can set the air conditioner temperature 2-3 degrees higher and the room cools quickly, reducing electricity bills. Ventilation can also be done quickly, and when used with a dehumidifier, it is useful for lowering humidity.

Vornado Korea is introducing two new Vornado DC models that enhance air circulation effects while reducing power consumption by 80%.

The newly launched Vornado DC (direct current) models are ultra-energy-saving air circulator models that have relatively lower heat generation, power consumption, and noise compared to existing AC (alternating current) models. The DC models, applying Vornado's exclusive "Energy Smart™" technology, reduce power while strengthening air circulation effects, making them useful for efficient energy savings during periods of increased summer cooling usage.

Additionally, the existing three-stage wind speed adjustment function has been changed to a stepless method, allowing free setting of desired wind speeds without stage limitations. As the first in the industry, motor warranty has been extended from the existing 5 years to 10 years.

Inca Solutions energy-saving multi-outlet "Check Tap"

Inca Solutions (CEO Lee Jung-soo, www.incas.co.kr) presents the energy-saving multi-outlet "Check Tap."

Check Tap consists of a main unit (digital multi-outlet), software, and USB data cable. When computers or peripheral devices are left on but not actually in use, the power to each device is automatically cut off in a gradual, selective, or collective manner, enabling energy savings of approximately 50% of total power usage.


Additionally, energy savings and power consumption amounts and CO2 reduction amounts are recorded and analyzed in real-time, generating customized energy-saving reports.

The new model features central monitoring and analysis report functions, with energy-saving results from PCs where Check Tap is installed automatically transmitted to a server PC, where an energy-saving results analyzer installed on the server PC generates energy-saving performance analysis reports including daily, monthly, annual, and period-specific energy-saving amounts and savings, CO2 reduction results, and investment recovery periods.
