The QuasarLR is powered using 24 V DC which are connected at the front of the device. If
you do not use a power supply supplied by metraTec, please make sure that your own PSU
provides a supply voltage of high quality. If possible, use a PSU with high precision/high
speed linear regulator. If you use a switching PSU, please make sure that the switching
frequency is > 500 kHz.
