Description
RQ-125B series is a 125W quad-output enclosed type power supply with 38mm of low profile design. The AC input is 88 ~ 132VAC / 176 ~ 264VAC (selected by switch) which could be directly supplied from the house supplied voltage. The output Voltages from SMPS will be +5V, +12V,-5V, -12V. The SMPS has high efficiency up to 77%, the design is of metallic mesh case which enhances the heat dissipation of RQ-125B that the whole series operates from -25°C through +70°C. RQ-125B has complete protection functions and 5G antivibration capability; it complies with international safety regulations such as UL62368-1, TUV BS EN/EN62368-1. RQ-125B series can be used for many purposes with the best performance from it.
