USER INSTRUCTIONS
1) DESCRIPTION
DIN Rail Universal Active ORing Controller for redundant connection to a common Load of 2 DC Power supplies of same rating, with any voltage in the range 12 – 85 VDC
and Load Current ≤ 50 A.
Warning: Voltages ≥ 60 VDC are dangerous! Use appropriate safety rules!
2) INSTALLATION
Use DIN-rails according to EN 60715. Installation should be made vertically (see Fig.4). For better device stability fix the rail to the wall close to the point where the device
is to be mounted. In order to guarantee sufficient convection, we recommend observing a minimum distance to other modules (see Fig.3).
3) CONNECTIONS
The device is equipped with pluggable screw terminals. To avoid sparks, do not connect or disconnect the connectors before having previously turned-off input power
and waited for internal capacitors discharge (minimum 1 minute)
In order to comply with UL certification, use appropriate copper cables of indicated cross section, designed for an operating temperatures of:
60°C for ambient up to 45°C
75°C for ambient up to 60°C
90°C for ambient up to 70°C
Strip the connecting ends of the wires according to the indication and ensure that all strands of a stranded wire enter the terminal connection (see Fig.5)
4) INPUT / OUTPUT CONNECTION
The device is suitable for SELV and PELV circuitry (if you use a source with Vout higher than 60 VDC it is not a SELV device)
Check Vout before connecting the power supply to the load.
5) OPERATION
Connect the LDX-D50 as indicated in Fig.7.
Turn on power supply “A” and adjust the load voltage to the needed level by measuring directly at the load.
Turn on power supply “B”. Trim its voltage until the green LED in the LDX-D50 bar-graph is lit. At this moment power supplies “A” and ”B” share the load with balanced
currents.
In case one of the two power supplies does not operate anymore the load is supplied by the second one without any interruption.
6) STATUS SIGNALS
LDX-D50 provides specific status signals related to:
• acknowledgment of the power supplies availability (correct output voltage for each) (OR OK)
• correct current share between the two power supplies (SHARE OK)
• load current > 50 A (OVERLOAD)
These signals are displayed on the LDX-D50 front panel trough LEDs and are also present on 2 relays dry contacts for remote monitoring of the unit.
IN1 (IN2) OK LED: Indicates that the voltage present on IN1 (IN2) is > 0.9*Vout. It is an indication of the presence of the correct voltage from the power supply connected
to IN1 (IN2).
FAIL LED: Indicates that the system has a problem and the redundancy is no more guaranteed. It can have 3 status
• OFF continuously: means that the redundancy is guaranteed. In this status the OR-OK dry contact is closed
• ON continuously: means that the voltage on one of the two inputs is not present or out of range. In this status the OR-OK dry contact is open
Blinking at 0.5 Hz: means that the output current has exceeded the maximum of 50 A. In this status the SHARE-OK dry contact is closed and open at
0.5 Hz rate (1s ON / 1s OFF).
Current share bar-graph: Indicates the current distribution between the two power supplies. The current balancing is calculated in the following way: unbal = (I1-
I2)/(I1+I2); bal = 0% means perfect current sharing while unbal = 100% (-100%) indicates that the load current is provided only by power supply 1(2).
The central green LED has a threshold of around ±15% current unbalancing, while the two external red LEDs are actives when the current unbalancing is greater than
60%.
When one of the two red LEDs is on the SHARE-OK dry contact is open.
Note: when the load current is < 2 A the bar-graph green LED is always on and the SHARE-OK dry contact is always closed.
The current unbalancing is not calculated when the load current is < 2 A.
OR-OK relay dry contact: It acts in exactly the same way as the FAIL LED. It is closed when the redundancy is guaranteed and open in case of failure.
The relay contact rating is 24 V / 1 A
SHARE-OK relay dry contact: It is closed when the load current unbalance is <60% and open when the current unbalance is > 60% indicating that the current sharing
between the two sources is lost. It toggles at 0.5 Hz rate (1s closed / 1s open) when the load current exceeds 50 A.
