(1) See Temperature vs Power curve. Maximum Power Rating (W) = Nominal Output Volts (V) x Maximum Output Current (A). Reducing voltage allows operation without degradation at higher current as long as maximum power rating is not exceeded.
(2) Overcurrent Limit is rectangular (50W) or hiccup type (100W, 150W). After the overload is removed, output is automatically restored.
(3) Identical units may be paralleled, however forced current sharing is not available.
(4) T, C, X and Y Suffix models only.
(5) 3.2A Peak (Peak current and thermal protection applicable to 24V standard (no options) and C suffix models only; see 24V Peak Current Requirements).
(6) 3.3A min for 24V standard (no suffix) and C suffix 50W models only.
(7) 10A Peak (Peak current and thermal protection applicable to 24V standard (no options) and C suffix models only; see 24V Peak Current Requirements).
