■ Description
NTS-250P is a 250W highly reliable built-in type off-grid true sine wave DC-AC power inverter. Its key
features include: digital design with MCU control, streamlined control circuitry that quickly responds to
environmental changes and improves reliability, compact size, light weight, fanless quiet design, 500W
peak power, adjustable AC output voltage and frequency, -20~+70℃ wide operating temperature range,
built-in remote ON/OFF control, low no-load power consumption (energy saving mode < 1.5W max.),
complete protection features, and etc. Combined with batteries, the NTS-250P is suitable for use in
residential, commercial, marine, automobile, and remote areas with no access to utility power, and the
output can be used to power fans, TV, radio, phone charger, PC/laptop, lighting, outdoor camping
equipment, marine AC power, and etc.

1.Efficiency, AC regulation and THD are tested by 250W, linear load at 12.5Vdc/25Vdc/50Vdc input voltage.
2.All parameters not specified above are measured at rated load, 25℃ of ambient temperature and set to factory setting.
3.The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the
EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
