Details
Meanwell ENP-120-48 is 120W desktop type power supply with 55.2V2.2A350mVp-p47.5-58.8V. The item works perfectly for communication related applications, and offers the most frequently used voltage in the communication field. Based on the rugged mechanical design and the high efficiency circuitry, ENP-120-48 could operate for the ambient temperature range -30℃~+70℃ under free air convection. Compared with ESP and ESC, the product has significant improvement: wide input range (88~132VAC / 176~264VAC→90~264VAC), new active power factor correction function (Active PFC), extended warranty period (2 years→ 3 years), 7" standard width and complete safety certification (UL/CUL/CB/CE/FCC). Apart from them, the model complies with the latest global energy consumption standards EISA 2007/DoE Level VI, NRCan, EU ErP and CoC Fifth Edition. This permits Meanwell ENP-120-48 ideal for applications such as radio system redundancy solutions, land radio systems, monitoring systems, electric and bicycle chargers, etc.
