1 Rectifier DPR 2900. Description The DPR 2900 rectifier is part of DELTA 's EnergE. Series with 96 %, high efficiency standard. Combined with market's leading Power density DELTA DPR 2900. is ensuring cutting edge total energy efficiency. The robustness to operate in harsh temperature environ- ment allows increasing temperature settings of the cooling infrastructure, which bring additional energy saving in the installation. This rectifier is optimal for 1U Solutions and provides in one shelf. Installation is simplified as all DELTA rectifiers have DELTA rectifiers are market leaders in Power their connectors at rear and are hot-pluggable.
