DC power supply requirements
Standard DC units powered by 12VDC power supply may draw up to 1.2A of
current steady state. Low power DC units may draw up to 0.25A of current
steady state. Peak inrush is 42A at 42VDC supply, lasting approximately 1ms.
Inrush for other supply voltages can be estimated with: Inrush (Amps) =
Supply (Volts) / 1.0
