[Free Catalog Available!] What is "Stage Charging," which is also featured in our battery chargers? [Basic Knowledge Material]

A compact battery charger suitable for various charging applications.

The "GC Series" is a charger that employs a "two-stage charging" method to achieve high efficiency and extend battery life. The two-stage charging consists of an initial charging phase and a float charging phase. It is used as an embedded unit in chargers and is incorporated into portable power units and UPS systems. 【Features】 ■ Two-stage charging method ■ Wide input voltage: AC90–264V ■ Wide temperature range: -30℃ to +60℃ ■ W testing conducted in Taiwan and Japan ■ Primary and secondary side insulation design ■ Various protective functions included *For more details, please refer to the PDF document or feel free to contact us.

A "tough charger" that endures even in harsh environments.

The HEP Series is a battery charger that supports a wide range of input voltages with a three-stage charging method. Despite being a "high-quality" charger with various functions and features, the HEP Series is also "tough." It is designed with an aluminum case filled with thermally conductive silicone, allowing it to withstand applications in environments where high temperatures, high humidity, dust, high vibration (10G), oil (including machine oil), steam, altitude, oil smoke, and corrosive gases may occur, making it widely adopted due to its toughness. It is equipped with a PFC power factor correction circuit. The output voltage and current can be adjusted via an internal potentiometer. 【Features】 ■ High efficiency of 93.5% to 95.5% ■ Equipped with PFC (Power Factor Correction) circuit ■ Output voltage and current adjustable via internal potentiometer ■ Aluminum housing with high heat dissipation effect ■ Suitable for lead-acid and lithium-ion batteries ■ Employs stage charging *For more details, please refer to the PDF document or feel free to contact us.

iPick Co., Ltd., a partition manufacturer, will explain the definition of non-combustible materials under the Building Standards Act and their importance in office interiors. Fire-resistant materials are classified into three categories: non-combustible, quasi-non-combustible, and flame-retardant, based on safety during a fire. At iPick, we handle aluminum partitions that have received non-combustible certification, demonstrating high fire resistance, which is required by "interior restrictions" depending on the size and use of the building. Selecting appropriate materials is crucial not only for protecting the lives of employees but also from the perspective of asset protection and business continuity planning (BCP). We propose the creation of safe spaces that balance compliance with regulations and design. ＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊ For the design and construction of interior partitions from offices to toilet booths, leave it to iPick, the partition specialist manufacturer!
