Power Supply
A high level of power supply filtering has been built into the unit, to meet EMC/EMI compliance.
However, a power supply with low noise and ripple levels, and adequate transient response is still recommended.
The unit contains a fully isolated power supply and has separate grounds for power and signals to ensure that power supply noise does not corrupt communications or cause ground loops with other equipment.
The power supply must be able to reliably provide the maximum current at the chosen voltage, especially in systems with substantial load variations. Make sure that all system components are rated (including safety factors) for the anticipated environmental operating conditions and stressors of the system. Refer to the Hardware Specifications for further information.
The unit contains an active protection circuit on the power supply input that protects the unit from:
- Under Voltage
- Over Voltage
- Reverse Polarity
It is recommended to always operate the unit at a voltage higher than the minimum mentioned in the Electrical Specifications. Take caution when using a supply voltage close to the minimum voltage as minor voltage fluctuations could trigger under-voltage protection, leading to unexpected oscillations between the on and off states.
