Both products are low power output types, suitable for operation at low voltages. To suppress AM band noise, they use high frequency sine wave oscillation. Both products are available in two output voltages, allowing the user to select the most efficient voltage for the equipment. The products have built-in rectifier diodes and small packages, contributing to equipment miniaturization.
