Product Overview

 

Delta Electronics CliQII  DC-UPS Modules

The CliQ II Delta’s Chrome DC-UPS module is designed to use in small cabinets where space is very critical. The module requires less installation space due to its flat body with depth of only 55.6mm, 71mm wide and 91mm tall. The tough plastic case has flame retardant property certified to UL 94V-0 specification. The module supports 24Vdc system with external battery up to 12AH capacity and comes with potential free contacts for battery management signals and LED indicator for battery status. The highly efficient convection cooled design is certified to major safety approvals including IEC/EN/UL 60950-1 for ITE and UL 508 for Industrial, which allows the module to be used reliably in most industrial applications.
