2400W Single Output Power Supply 2.Alarm Signal Output (1)Alarm signal is sent out through "P OK" & "P OK GND" and P OK2 & P OK GND2 pins. (2)An external voltage source is required for this function. (3)Table 2.1 explains the alarm function built-in the power supply. Function Description Output of alarm(P OK, Relay Contact) Output of alarm(P OK2, TTL Signal) The signal is "Low" when the power supply is above Low (0.5V max at 500mA) Low (0.5V max at 10mA) 80% of the rated output voltage-Power OK P OK High or open The signal turns to be "High" when the power supply High or open is under 80% of...

2400W Single Output Power Supply (1)Parallel operation is available by connecting the units shown as below (+S.-S and CS are connected mutually in parallel): (2)The voltage difference among each output should be minimized that less than ±2% is required. (3)The total output current must not exceed the value determined by the following equation. (Output current at parallel operation)=(The rated current per unit) x (Number of unit) x 0.9 (4) In parallel operation 3 units is the maximum, please consult the manufacturer for other applications. (5) When remote sensing is used in parallel operation,...
