Please refer to the full part number structure for additional ordering part numbers and options.
➁ All specifi cations are typical at nominal line voltage and full load, +25ºC. unless otherwise noted.
Units are tested with a 1uF ceramic external output capacitor and a 100uf and 2.2uF external
input capacitor.
➂ Full power continuous output requires baseplate installation. Please refer to the derating curves.
