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
