Enclosed AC-DC switching single output power supply with battery charger (UPS Function) Two modes for output voltage (simultaneously, through two channels). Depending on the chosen model, the current intensity may vary for each channel. With power LED indicator and overloading protection, short-circuit and over voltage. Cooling by free air convection. Fixed switching frequency at PFC 67 KHz and PWM 134 KHz. The output power rate oscilates between 149,9W and 152,75W depending on the chosen model.
