DESCRIPTION
The PSDN-40 series of AC/DC DIN Rail power supplies provides 40 Watts of continuous output power. All models have a
single output and a universal input range. All models are over load, over voltage, and short circuit protected.
SPECIFICATIONS: PSDN-40 Series
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.
We reserve the right to change specifications based on technological advances.

NOTES
1. Ripple & noise is measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1µF & 47µF capacitors
in parallel.
2. Tolerance includes set up tolerance, line regulation, and load regulation.
3. Derating may be needed under low input voltages. Please check the derating curve for more details.
4. The power supply is considered a component, which will be installed into final equipment. The final equipment must be
re-confirmed that it still meets EMC directives.
5. In parallel connection only one unit may operate if the total output load is less than 5% of the rated load.
