Performance/Functional Specifications
Typical at TA = +25°C and VIN = 85-264V @47-63Hz
➀ All models will also operate from a regulated and filtered 110 to 340Vdc input.
➁ Unless 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.
➂ Transient response is defined as the output returning to within its specified
tolerance in 10ms or less, following a 90% load change.
