NTS-250P/400P Series

In order to meet market demand for more cost-effective inverters, MEAN WELL has planned a new-generation NTS/NTU family of 250W~3200W inverters. The first products to be launched are the MEAN WELL pioneered built-in type DC-AC pure sine wave inverters, the NTS-250P/400P series. Key product features include:
  • DC-AC pure since wave output
  • Convection cooled fanless design, high efficiency up to 93%
  • 200% Peak power capability (NTS-250P up to 500W, NTS-400P up to 800W)
  • Built-in DIP switches to adjust AC output voltage, frequency, and work mode
  • Energy saving mode no load power consumption
  • -20~+70℃ ultra-wide operating temperature
  • Built-in remote ON/OFF control
  • Support Tx /Rx computer communication interface to monitor inverter status
  • Multiple intelligent protection functions (abnormal automatic shutdown):
    DC input side – reverse polarity, under voltage, over voltage protections
    AC output side – short circuit, overload, over temperature protections
  • PCB conformal coating, protection from moisture / dust / dirt
  • Wide DC voltage input range, suitable for lead acid and lithium batteries
  • Safety approvals: CB, E13, EAC, RCM, CE, FCC
  • Dimensions (L x W x H): 186 x 100.5 x 32mm
  • 3-year warranty


To offer more SELV(Class III) DC input step-down LED drives for the promising market of the safety Low-voltage centralized bus, MEAN WELL has developed two direct current (DC) input LED drivers, NLDD-H and LDDS-H series. Key product features include:
  • Wide DC input Voltage operation
  • Wide output forward voltage design
  • Constant current output design
  • High efficiency up to 96%
  • Protections: Over temperature/ Short circuit
  • Compact size and Fully encapsulated
  • 3 years warranty (NLDD-H) and 5 Years warranty (LDDS-H)

HEP-1000-W Series

To provide a complete harsh environment power supply product, MEAN WELL has released new HEP-1000-W series. The difference between this series and the previous HEP-1000 product lies in that the input and output adopt the waterproof wires, meeting the IP67 standard. Key product features include:
  • Fanless and fully-potted design for harsh environment
  • PFC design and High efficiency up to 96%
  • Wide working temperature range : -40~+70℃
  • Withstand 10G vibration test
  • Built-in 2/3 stage charging curves and programmable curve
  • Output voltage and constant current level programmable
  • Protections : Short circuit / Overload / Over voltage / Over temperature
  • Built-in PMbus and CANBus protocal (optional)
  • Built-in DC OK active signal and 12V auxiliary power output
  • 6 years warranty
