Output and model selection

Complete model / series DETN02N-15 / DETN02. Input code N: 24 V nominal; output code 15: ±15 V dual output. No suffix selects the standard version.
Conversion and rated power Isolated, unregulated dual output; 2 W total rated power. The positive and negative rails share this total; rounded current values do not increase the rated power.
Output voltage and current ±15 VDC relative to Common; 6–67 mA per rail. Observe the stated minimum load on each rail.
Efficiency 80% typical for this model; the series feature statement is up to 83%.
Maximum capacitive load 220 µF, as listed in the model-selection table.
Voltage accuracy ±2.0%.
Line regulation 1.2% for 1% input variation; measured from low line to high line at rated load.

Input voltage 24 VDC nominal; operating range 21.6–26.4 VDC.
Input current No load: 15 mA; full load: 104 mA.
Input surge 30 VDC for 100 ms maximum; this does not extend the continuous input range.

Short circuit Standard version: 0.5 second maximum short-circuit duration.

Environment, reliability and compliance

Operating temperature and derating −40 to +100°C ambient, subject to the derating curve. Standard curve: 100% load through +90°C, 50% at +95°C and 40% at +100°C. The curve beyond +100°C does not extend the specified operating range.
Maximum case temperature +105°C maximum. The ambient range and derating curve do not override this case-temperature limit.
Cooling Free-air convection.
