Maas SPA-8350 Power Supply




SPA-8350: This range of super efficient power supplies delivers long term cost savings in energy costs, increased reliability, longer life and requires less warranty coverage. The zero voltage switching design reduces power dissipation in the switching transistors and the EMI level, resulting in a quiet (less switching noise) and cooler running power supply. It is especially suitable for telecommunications, long term use and in close proximity to other equipment. The circuit of the device is designed for the operation of radio devices and receivers and is also HF-proof and short circuit proof.
