"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.

Aren't you using a charger that has been unofficially customized? That is considered unregulated and the seller is also committing the same violation!

  • Product news

We are Earth Power Co., Ltd. Recently, robots and AGVs have been widely adopted and produced in Japan. Such robots and AGVs always require battery chargers, and we receive many inquiries about this at Earth Power. Q. Are there any battery chargers for unmanned transport vehicles that are safe to use and have obtained PSE certification? This is the question. Earth Power has also obtained PSE certification, so you can use our products without any issues. However, it seems that other manufacturers, in their attempt to produce at a low cost, have created products that do not meet the standards or lack after-sales service, leading to many problems. While it is understandable to prioritize "cost," it is important to note that the issues arising from focusing too much on cost can actually end up being more expensive. Regarding this issue, our battery chargers are shipped only as normal products, and we can provide certification documents. We also conduct warranty and repair analysis domestically. We have a wide range of products, so please visit our website for more details. Please note that this news may also have implications beyond just chargers.
