Input Voltage Range

The RPA200H series has an adjustable under voltage lockout which will shut down the

converter according to following settings.

Continuous full power operation is rated between 16.5V and 140V,

including full load start-up.

Once running, the converter will operate for short periods of time over

an extended input voltage range down to 14.4V and up to 156V, thus

covering all EN50155 under-voltage and over-voltage transient

conditions.
