November 8, 2021

November 8, 2021 MEANWELL New Product Launch

01. INTRODUCTION

MEAN WELL KULON adheres to the concept of environmentally friendly and sustainable development and promotes multi-purpose product designs to conserve resources. The newly launched MEAN WELL KULON product NPB-450 and NPB-750 series are unique 450W & 750W universal chargers with intelligence, wide voltage, multi-purpose design, flexible functions, safety and durability as their core features. The units are designed with built-in MCU and newly patented auto ranging battery detection technology, which will automatically adjust charging voltage settings depending on the battery voltage (Note this mode is only suitable for Li-ion batteries with BMS). Additionally, there are 12V(10.5~21V), 24V(21~42V), 48V(42~80V), and 72V(54~100V) four different models that come with a 2:1 wide charging voltage range. Each unit can be used for a wide range of batteries, so the users do no need to purchase multiple chargers due to variety of batteries. This not only saves costs for users, but also contributes to saving the environment for the next generation.

In addition to intelligent voltage detection, ultra-wide voltage, and universal applications, the MEAN WELL KULON product NPB-450 and NPB-750 series can also pair with the MEAN WELL KULON SBP-001 to connect to computer to program various parameter such as select 2/3 stage charging, adjust charging voltage/current, set charger timeout, etc. The charger parameters may also be adjusted manually via the user-friendly DIP S.W. on the front panel for the charging current (50~100%) or selection between the 4 preset curves. For more professional application integration, the MEAN WELL KULON product NPB-450/750 have built-in CANBus protocol, which allows remote setting and monitoring of the charger. In terms of safety features, the chargers detect if battery voltage is correct and if it is properly connected before it starts charging. The chargers also have reverse polarity protection. They are certified to ITE IEC/EN/UL 62368-1 and household appliances EN60335-1/-2-29 dual safety, ensuring reliable operation. Combined with 3 years warranty, they are universal intelligent chargers with excellent cost performance. The products are suitable for charging applications for electric motorcycles, unicycles, scooters, camping vehicles, UAV, mobile robots, hand-held power tools, floor scrubbers, etc.

As the global partner of MEAN WELL, KULON company introduces the latest products of MEAN WELL to customers, and provides samples for customers in need, as a test, welcome to contact us, we will provide you with high-quality services.
