Overview
What it is
The MEAN WELL NTS-250P-124 is a DC-AC inverter from the NTS-250P series (250 W High Reliable Built-in Type True Sine Wave DC-AC Power Inverter), rated 24 V DC to 110 V AC, 250 W.
What it is used for
PCB built-in inverter module that turns a 24 V battery supply into a true sine wave 110 V AC output, for building into equipment that needs AC power from a battery. MEAN WELL lists applications such as mobile devices, home and office appliances, off-grid solar power systems, telecom or datacom systems.
Key features
- True sine wave output (THD <3%).
- Surge power up to 500 W.
- AC output voltage and frequency selectable by DIP switch.
- Protections: reverse polarity, DC low alarm, DC low shutdown, over voltage; output short circuit, overload, over temperature.
- Battery over discharge protection (low voltage disconnect).
- Suitable for lead acid or Li-ion batteries.
Key Specifications
- DC Input Voltage: 24 V DC nominal (20 to 33 V DC).
- AC Output Voltage: 110 V AC default; 100, 110, 115 or 120 V AC selectable by DIP switch.
- Rated Output Power: 250 W continuous.
- Surge Power: 500 W for 30 cycles.
- Output Waveform: True sine wave (THD <3%).
Buying considerations
Size the unit with headroom above the connected load and check the derating information in the datasheet for high ambient temperature or low input voltage. Other models in the same series are listed on this page.
Installation considerations
MEAN WELL treats this unit as a component of the final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring and safety details are in the official datasheet linked below.
