Power Supply
Do not power up the EM20-M37 until it is properly connected. Be sure the power is cut off before connecting a cable to or
disconnecting a cable from the host interface connector. Hot-plugging could damage the engine.
Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may lead to unstable
performance of the engine. Do not resupply the power immediately after cutting it off.
Ripple Noise
To ensure the image quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak) :
≤
80mV
