NOTES:

1

Consult factory for availability of 28V and 48V units with DC input.

2

Output currents ratings are expressed with 300 LFM forced air.

3

Remote sense connected. See Application Note #P1 for load regulation when using the D option for 24V units.

4

Maximum peak to peak noise expressed as a percentage of output voltage, 20 MHz bandwidth. For ripple/noise on “D” option models,

see options data.

5

Models without suffix G use the lead solder exemption
