basic information

【 Power Mode 】 In power mode, in addition to the battery, you can connect a load, allowing for charging while also supplying power to the load. This mode does not bring the battery to a low voltage state, and since it can provide a stable supply to the load, it can be a suitable mode depending on the system. 【 Lineup 】 - NPP-450-12JP - NPP-450-24JP - NPP-450-48JP - NPP-450-72JP - NPP-750-12JP - NPP-750-24JP - NPP-750-48JP - NPP-1200-12JP - NPP-1200-24JP - NPP-1200-48JP - NPP-1700-12JP - NPP-1700-24JP - NPP-1700-48JP The dimensions and weight vary.

The "NPP Series" battery charger can also be used as an AC-DC constant voltage output power supply! It allows for charging while supplying power to the load! It can be used for various applications with full charging and stable supply.

  • Product news

Battery Charger "NPP Series" This product is equipped with two modes: battery charger mode and power supply mode. In battery charger mode, it performs excellently as a charger by utilizing stage charging! However! In power supply mode, it is possible to provide stable DC output while charging the battery and connecting a load to the unit! In the "3-stage charging" of the charger mode, it transitions from bulk charging to absorption charging and then to float charging. However, if a minimal load such as 5A is used, it may not transition to float charging and the charging will stop (it will not reach full charge). However, by using power supply mode, it can achieve a full charge while also providing stable power to the load. Once the battery is fully charged, it will only supply power to the load. By disconnecting the battery, it can also be used as an AC-DC power supply. For more details, please visit our website or view the catalog below.

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.
