DC power supply for notebook computers Ingestion-build-264231 BS EN 62087-3 includes measuring1 Scope This Technical Specification states the minimum requirements for DC power supply for notebook computers. Specifically, it gives an electrical specification (performance characteristics), an ID pin method, a connector for DC power output. The no load power and power efficiency are outside the scope of this Technical Specification. NOTE that safety requirements are covered by IEC 609501 and EMC requirements are covered by CISPR 22 and CISPR 24.
