What is "stage charging" in a battery charger? / I have summarized information about stage charging. Please check it out from the catalog download.

Compact battery charger suitable for various charging applications.

The "GC Series" is a charger that employs a "two-stage charging" method for high efficiency and long battery life. The two-stage charging consists of an initial charge and a float charge. It is adopted as a built-in 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 protection features included *For more details, please refer to the PDF document or feel free to contact us.

"Tough charger" that endures even in harsh environments.

The HEP Series is a battery charger that supports a wide input voltage range with a three-stage charging method. Despite being a "high-quality" charger with various features and characteristics, the HEP Series is designed with an aluminum case filled with thermally conductive silicone, making it "tough." It can withstand applications in environments where high temperatures, high humidity, dust, high vibration (10G), oil (including machine oil), steam, altitude, oil smoke, and corrosive gases are present, which is why it is 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 ■ Adopts stage charging *For more details, please refer to the PDF document or feel free to contact us.
