120W Waterproof LED Power Supplies

Mean Well Enterprise Co. Ltd. has expanded its offering of LED power supplies to include the NPF-120(D) and PWM-120. Following the features of the previously-introduced 40W, 60W and 90W, the NPF-120(D) and PWM-120 conform to the requirement for a power factor above 0.9, a set up time under 500ms, and a no load power consumption under 0.5W as regulated by the EU ErP directive. As a result of the IP67 protection level, these series fit the operation in highly dusty and humid environments.

Recommended: Extending PoE Transmission Range to 3000 Meters

NPF-120(D) series provide the ordinary dc style output, suiting various kinds of applications such as indoor LED lighting and LED decorative lighting. PWM-120 offers the pwm style output so that it can work with LED strips or the LED luminaries which have built-in current limiting resistors. Mean Well expects that these three series will all be the prevailing models in the LED power supply market.

These LED power supplies have an input voltage range of 90- to 305-Vac. The fanless design is 91% efficient and can be cooled with free air convection. They have an operating temperature range of -40 to +70 degrees C and include short-circuit, over-current (NPF series) or overload (PWM series), over-voltage, and over-temperature protection. These Class II power units (no FG) are packaged in a 94V-0 flame retardant plastic case measuring (L x W x H) 191 x 63 x 37.5mm. They carry approvals from UL/CUL/ENEC/CB/CE and have a five-year warranty.
