MEAN WELL GSV30 30W and GSV60 60W Wall-Mount LED Power Supplies are external wall-mounted LED power supplies with a power factor correction (PFC) function. These series have a constant voltage output with the European standard AC plug adapter, comply with Class II and SELV with double insulation design, in line with the European EN61347 and EN61000-3-2 Harmonic Class C lighting regulations. In addition, the no-load power consumption is less than 0.5W, making GSV30 and GSV60 conform to the ErP regulation required by European Union for lighting systems. There are three available output voltages of 12V/24V and 48V. This adapter can be directly used with LED light strips or used with any PWM or RGB dimming controllers.
