➀All models will also operate from a regulated and filtered 110 to 340Vdc input.
➁Unless otherwise specified, load regulation is measured with the output under test undergoing a load change of 100% to 50% at nominal line input and, when applicable, with all other outputs operating at 50% of rated load.
➂Transient response is defined as the output returning to within its specified tolerance in 10ms or less, following a 90% load change.
