REFERENCE DESIGNS DER-172: 70V @ 130mA, 108 ~ 132VAC in This power supply operates using input voltages ranging from 108 to 132 VAC. This ensures a DC bus voltage large enough to support a 70 V output. In a buck topology the output voltage is always smaller than the input voltage.

Identifying Capacitor Polarization

BLOG Identifying Capacitor Polarization Polarized capacitors will always have some sort of designator on them identifying polarity. This is important, because hooking one up backwards can be dangerous.
