MEAN WELL ENP-120-12 96W 12V 8A Battery Charger Power Supply with PFC

The MEAN WELL ENP-120-12 is a robust 96-watt battery charger and power supply that delivers a regulated 12V DC output at up to 8A. Its active power factor correction (PFC) and high efficiency make it an energy-conscious choice for demanding industrial and commercial charging applications.

Advantages

Built around a 2-stage constant current/constant voltage charging algorithm, the ENP-120-12 ensures safe and complete charging for lead-acid batteries. The integrated active PFC (PF > 0.95) reduces harmonic distortion and improves energy utilization, while the wide input range of 90–264 VAC allows operation from virtually any AC mains worldwide. Free air convection cooling eliminates fan noise and moving parts, enhancing reliability in dusty or vibration-prone environments. Comprehensive protections—including short circuit, overload, over voltage, over temperature, and battery reverse polarity—guard both the charger and the connected battery.

Suitable for

• Charging 12V lead-acid batteries in UPS systems, alarm panels, and emergency lighting
• Powering 12V DC equipment such as LED lighting, CCTV cameras, and industrial controls
• Portable or stationary applications requiring a compact, fanless power source
• Installations with fluctuating or unstable AC mains due to the wide input voltage range
