A31 INVERTER Ferroresonant Technology

The La Marche A31 Inverter is designed based on robust ferro technology. This DC-AC pure sine wave inverter utilizes IGBT Switching to assure reliable performance. The 22U Series provides a wide range of features such as static transfer switch and a 4-line LCD display for monitoring. It incorporates a DC input breaker and an automatic under/over voltage shutdown circuit to protect the inverter and battery. The A31 has a polarity indicator to tell you if the battery is connected incorrectly. The La Marche A31 is equipped with an input filter pre-charge circuit which includes an indicator to inform you that the inverter is ready for operation. Applications may include data centers, fire alarms, telecommunications, emergency lighting, security, oil exploration and utility substation systems.

ADVANTGAES:

 

Highly Reliable Ferroresonant Transformer Design. Ferroresonant transformers are known for their ruggedness and ability to handle electrical noise and voltage fluctuations, making this inverter ideal for harsh industrial environments and mission-critical applications where reliability is non-negotiable.

 

Pure Sine Wave Output. A pure sine wave ensures clean, stable power for sensitive equipment like servers, communication systems, and control units. It prevents malfunctions or damage that might occur with modified or square wave inverters.

 

Digital Static Transfer Switch (DSTS). The DSTS enables instantaneous switching (within milliseconds) to an alternate power source if the main inverter path fails, ensuring uninterrupted operation for essential loads such as emergency lighting or telecom systems.

 

Comprehensive Protection Features (Over/Under Voltage, Polarity, Overload). Built-in protection features like automatic shutdown for over/under voltage, polarity indicator, and overload protection help protect both the inverter and connected equipment, reducing maintenance costs and preventing downtime.

 

User-Friendly Monitoring & Diagnostics (LCD Display + LEDs). The 4-line LCD display and alarm LEDs offer real-time insight into system status, voltages, and alarms, enabling fast troubleshooting and ensuring operators can monitor performance with ease.
