Foreword
This Standard is drafted according to the rules in GB/T 1.1-2009.
This Standard replaces GB/T 19826-2005 ?€?General specification and safety requirements for DC power supply equipment of power project?€?. Compared with GB/T 19826-2005, the main technical changes in this Standard are as follows. - ADD the requirements of integrated power supply equipment;
- CHANGE the range of AC input voltage from (85 % ~ 115 %)Un to (85 % ~ 120 %)Un;
- CHANGE the ripple coefficient to ripple factor, which is redefined and coordinated with other standards;
- ADD the requirements of soft start characteristic;
- DELETE the requirements of other charging units;
- DELETE the requirements of cadmium-nickel storage battery.
This Standard is proposed by China Electrical Equipment Industry Association. This Standard is under the jurisdiction of National Technical Committee on Measuring Relay and Protective Equipment of Standardization Administration of China (SAC/TC 154).
