Company Profile

JKW Technology Co., Ltd

Power supplies · AC adapters
LED drivers · Battery chargers
PoE midspans · Electronic ballasts

JKW Industrial Co., Ltd. was founded in January, 2009. We are specialized in manufacturing lithium battery chargers which can be largely applied for E-motorcycles, E-sweepers and E-forklifts. We adopt high-rate switching mode technology. Our chargers are high quality, stable, smart, portable and efficient (up to 93%). They have aluminium case, elegant appearance, light weight and small size.

We own high-level developing engineers and manufacturing staff, and have ability to handle large orders. Our company has a group of engineers who have been in this field for more than 40 years both in production and management, and a group of young and knowledgeable people with doctor degrees who are skilled in high-tech and innovative thinking.

    US Department of Energy (DOE): Energy Conservation Program

     
     
     

    Mandatory requirement February 10, 2016

    US Department of Energy has created a new standard governing the efficiency in external power adapters. The Energy Policy and Conservation Act (EPCA) covers a wide range of consumer, commercial and industrial equipment, including and external power supplies. The new EPCA would expand the 2007 EISA program to include a much wider variety of a power supplies including multiple output EPSs.

    Naming Conventions

    EPS is External Power Supply
    Pno is the nameplate output power of the unit under test. Ln refers to the natural logarithm.
    Low Voltage EPS is an EPS where the output voltage <6V. This specification is accepted as Level VI under the International Efficiency Marking Protocol.

    The following are exempt from this regulation:

    • Open Frame Power Supplies
    • LED Drivers
    • Active POE Power Supplies
    • Power Supplies for Medical Application
    • Power Supplies with Output <3V and >1A
