If you decide not to use the standard 50 VDC power supply unit and want to power the device with other voltages (7-57 VDC{{#ifeq:{{{name}}}|TSW304| or 9-40 VAC|}}), please make sure that you choose a power supply of high quality. Some power supplies can produce voltage peaks significantly higher than the declared output voltage, especially during connection and disconnection. | If you decide not to use the standard 50 VDC power supply unit and want to power the device with other voltages (7-57 VDC{{#ifeq:{{{name}}}|TSW304| or 9-40 VAC|}}), please make sure that you choose a power supply of high quality.
