Description
The new Redundancy Module DRR 20A is the latest offering from one of the World’s No.1 Power Supply
Company. The product offers a variable input & output voltage from 22-60V, a wide temperature range from
-40°C to 80°C. The state-of-the-art design is made to withstand harsh industrial environments. The rugged,
compact aluminium case is shock and vibration resistant according to IEC60068-2-6. Due to the wide input
& output voltage range from 22 to 60Vdc, the Delta’s CliQ II Redundancy Module is able to support power
supply in parallel operation. The DRR module has an alarm relay contact as an indicator.

Derating Curve: Model DRR 20A, 40A
NOTE
1. Do not use the Redundancy Module in areas outside the shaded portion as shown in the above
graph, internal parts may occasionally deteriorate or be damaged.
2. For the power derating refer above graph ambient temperature > 50°C, the output capacity has to
be reduced by 2.5% per degree Celsius increase in temperature. If the output capacity is not
reduced when Amb > 50°C, some device will run into thermal stress problem, the ORing diodes
will get too hot.
3. If the Redundancy Module has to be mounted in any other direction please contact your service
provider.
4. In order for the device to function in the manner intended, it is also necessary to observe lateral
spacing of 20mm. to other modules.
5. Depending on the ambient temperature and load of the device, the temperature of the housing can
become very high!

Redundancy operation with DRP 20A- (40A)
Parallel Operation
When 2 Power Supplies are connected in parallel, they can share the load if the following steps are taken.
Step1. Measure the output voltages at no load from Anode1 to Ground i.e. Voltage Anode1 to Ground of PSU1 and
Voltage Anode2 to Ground of PSU2. If the voltages are not the same, follow Step 2. If they are the same, skip to Step 3.
Step2. . Adjust the output voltages, with the help of VR on the Power Supply front panel market as ADJUST, to the
same level. For e.g. if PSU1 is measuring 24.15Vdc and PSU2 is measuring 24.25Vdc, adjust the output voltage of one
to be the same as the other
Step3. Connect the Power Supply to the end system load and measure the output voltages from A1 to Ground i.e.
Voltage Anode 1 to Ground of PSU1 and Voltage Anode 2 to Ground of PSU2. Ensure that the output voltages are the
same even after the 2 Power Supplies are connected to load. If not, adjust them with the VR available on the front panel.
A tolerance of +/-25mV would be acceptable.
Note
1)
If the output voltage of any Power Supply is higher, it will take the initial load and share the maximum load.
2)
If the output voltages are the same, then an equal load current sharing between the 2 Power Supplies can be
achieved.
3)
The ORing diode must be of an appropriate rating. The rating must be at least 4 times of the output load current
and at least reverse voltage rating of 20Vrr.
4)
The use of a heat sink is advised to ensure the ORing Diode does not overheat.
