Phototherapy, or heliotherapy, is the treatment of skin disorders using light. Systems are now using LEDs and target the skin with precise light wavelengths from red, blue and near-infrared LED sources that control the depth of the skin treatment. Output power is also adjusted to reach the target cells.

Looking for a 24V output Class II (no earth ground connection) medical power supply that had very low audible noise, designers of a new LED phototherapy machine chose TDK-Lambda’s XMS500 configurable medical power supplies. Options selected were the remote on/off and a 12V 1A standby voltage, so that the main 24V output powering the LEDs could be disabled and power still be supplied to keep the system processors operational.
