terminals 23, 24 : relay contact redundancy Output type : relay contact load share
- contact is closed if the adjustment of the output voltages are sufficient
- contact is open if an even load share does not occur and readjustment of the output voltage is required
relay contact redundancy
- contact is closed if no fault is detected
- contact is open if one or both input voltages are below 22 V DC or above 30 V DC
- contact is open if the output current is higher than the adjusted value of the output current
- contact is open if an internal defect of the device is detected Contact loading : max. 60 V DC/0.3 A ; 30 V DC/1 A ; 30 V AC/0.5 A resistive load
min. 1 mA at 5 V DC Input/Output : SELV/PELV Display elements : LED green: output status
- LED lights up if the output current is smaller than the adjusted value of the output current
LEDs green: load share status
- LEDs indicate the load share status between the two power supplies
LED green: redundancy status
- LED lights up if no fault is detected
- LED flashes if one ore both input values are below 22 V or above 30 V
- LED flashes if the output current is higher than the adjusted value of the output current
- LED flashes if an internal defect is detected Control elements : rotary switch Configuration : setting of the output current via rotary switch
- switch setting to 5 A in combination with two 5A power supplies (1+1 redundancy)
