Output and model selection

Model DLC03A-15
Output type Isolated, regulated dual output; positive and negative rails referenced to Common.
Output voltage ±15 V DC relative to Common.
Output current 0–100 mA per output rail.
Rated output power 3 W total across the positive and negative outputs; observe the current limit of each output.
Typical efficiency 81% at nominal input and rated load, 25°C and 70% RH.
Maximum capacitive load 220 µF per output.
Voltage accuracy ±2%.
Ripple and noise 50 mVp-p. Measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Line regulation ±0.2%, measured from low input to high input at rated load.
Load regulation ±0.5%, measured from 10% to 100% rated load.
Switching frequency 100 kHz typical.

Input and protection

Input voltage 9–18 V DC; 12 V DC nominal.
Input current 32 mA at no load; 313 mA at full load.
Input surge voltage 25 V DC for 100 ms maximum.
