General Description
Delta CliQ II Buffer Module offers the most widely used output voltage of 24V and one of the longest buffering time of 0.25 sec (min) at
20A in wide input range from 22.8Vdc to 28.8Vdc. The Buffer Module utilizes maintenance-free electrolytic capacitors to store energy,
thus eliminates the need of periodic replacement as compared to costlier batteries which also have shorter functional life span. Delta CliQ
II Buffer Module comes with comprehensive protection features like overcurrent/overload, overvoltage and short circuit protection. Delta
CliQ II series of products is IP20 compliant with full corrosion resistant Aluminium chassis and conformal coating on the PCBAs to provide
protection against dust and chemical pollutants.

Components may degrade, or be damaged,
when the buffer module is continuously used
outside the shaded region, refer to the graph
shown in Fig. 2.
In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance of 20mm with adjacent units
while the device is in operation.
Depending on the surrounding air temperature
and output load delivered by the buffer
module, the device housing can be very hot!
If the device has to be mounted in any other
orientation, please do not hesitate to contact
[email protected] for more details.

Assembly & Installation
The buffer module can be mounted on 35mm DIN rails in accordance with EN60715. The device should be installed with input / output
terminal block at the top.
Each device is delivered ready to install.
Mounting
Dismounting
Fig. 3.1 Mounting
Fig. 3.2 Dismounting
Snap on the DIN rail as shown in Fig. 3.1:
1. Tilt the unit upwards and insert it onto the DIN rail.
2. Push downwards until stopped.
3. Press against the bottom front side for locking.
4. Shake the unit slightly to ensure that it is secured.

ALWAYS switch mains of input power OFF before connecting and
disconnecting the input voltage to the unit. If mains are not turned
OFF, there is risk of explosion / severe damage.
To guarantee sufficient convection cooling, keep a distance of
50mm above and below the device as well as a lateral distance of
20mm to other units.
Note that the enclosure of the device can become very hot depending
on the surrounding air temperature and load of the power supply. Risk
of burns!
Only plug in and unplug connectors when power is turned off!
DO NOT insert any objects into the unit.
Hazardous voltages may be present for up to 5 minutes after the input
mains voltage is disconnected. Do not touch the unit during this time.
The power supplies unit must be installed in an IP54 enclosure.
The power supplies are built in units and must be installed in a cabinet
or room (condensation free environment and indoor location) that is
relatively free of conductive contaminants.
All parameters are specified at 25°C ambient unless otherwise noted.

Inrush Current
Inrush current is the peak, instantaneous, input current measured
and occurs when input voltage is first applied. For DC input
voltage the maximum peak value of inrush will occur during the
first applied DC voltage.
Overload & Overcurrent Protections
When the output current exceeds 120% of IO (Max load) buffer
module will shut down and latch. Normal operation of buffer
module can be resumed upon removal of fault and power supply
input is recycled (ON/OFF) or input to buffer module is recycled.
Short Circuit Protection
Overvoltage Protection
The buffer module’s overvoltage protection will be activated when
DC input to the module exceeds the maximum specifed input
voltage. The overvoltage limits are same as power supply limits,
32V ± 10%. Buffer module will shut down and latch during
overvoltage mode, and will return to normal operation upon
removal of fault and power supply input is recycled (ON/OFF) or
input to buffer module is recycled.
10
Buffer module is protected by short circuit during buffering mode,
in the event of short circuit the module will shut down and latch.
Operation can be resumed upon removal of fault and power
supply input is recycled (ON/OFF) or input to buffer module is
recycled.

Delta RoHS Compliant
Restriction of the usage of hazardous substances
The European directive 2011/65/EC limits the maximum impurity level of homogeneous materials such as lead,
mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and
electronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in
electrical and electronic equipment”.
This product conforms to this standard.
Conformal Coating
The Protective Coating Technology
Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including
under device, and prevents leakage. The conformal coating dipping can be applied to PCBs or circuit board.
The coating preserves the performance of precision electronic primarily by preventing ionizable contaminants
such as salt from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem
especially in highly conversing atmosphere.
