enclosed case. This series has a universal input voltage range of 90~264VAC (127~370VDC) and single outputs of 12, 15,
24, 27, and 48VDC. Standard features include high efficiency up to 90%, active power-factor-correction, programmable
output voltage and output current, remote on/off, remote sense, power OK signal, and internal ball bearing fan. This series
also has over voltage, short circuit, over load, and over temperature protection. All models are RoHS compliant and have
UL/cUL, TUV, and CE safety approvals.

NOTES
1. Ripple & noise is measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1µF capacitor and a
47µF capacitor in parallel.
2. Tolerance includes set up tolerance, line regulation, and load regulation.
3. For voltages near the low end of the input voltage range, see the derating curve for the power supply output rating.
4. When in parallel operation only one unit might operate if the total output load is less than 5% of the rated load condition.
5. 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.
