NOTES

1. The output voltage is specified as a range (Ex: 17 – 23 VDC); the customer must specify what they would like the output

voltage set at otherwise it will be the preset voltage.

2. PSRL9827Fx Series, identical to PSRL9827Sx except with cover and DC fan installed.

3. PSRL9827S Series: 150W max. with 16CFM forced air flow offering; 100W max. under air convection. (Option: Top Cover

Type A or B)

4. PSRL9827F Series: 150W max. with Top built-in Fan flow.

5. Providing peak power to 600W within 500uS for all models, longer duty duration need contact manufacturer.

6. Ripple and noise is measured from 10KHZ to 20MHz bandwidth at output with parallel 0.1uF ceramic and 22uF electrolytic

capacitors.

7. 1% minimum load is required to maintain the ripple and regulation.

8. Output is fully isolated.
