NOTES: 1) Output currents ratings are expressed with 300 LFM forced air.

2) Peak loads up to 450 Watts for 60 seconds or less are acceptable, (10% duty cycle max.). Peak power must not exceed 450 Watts.

3) Maximum peak-to-peak noise expressed as a percentage of output voltage, 20 MHz bandwidth.

4) V3 and V4 may be series connected to obtain 48V.
