cations that apply to all standard models are listed in the
paragraphs following Table 1. Other models are also avail-
able; consult your Kepco representative for their specifica-
tions.

(1) Derates same as Output Power.
(2) Current Limit is rectangular. After the overload is removed,
output is automatically restored.
(3) See power derating curve, Figure 4.
(4) Peak current and thermal protection applicable to 24V model only.
See Figure 1 for peak power requirements.
(5) Ripple and noise will be approximately 1.5 times higher when
operating temperature range is between –10°C to 0°C.
