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.
