NOTES:

1

Output currents ratings are expressed with 300 LFM forced air.

2

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

3

Peak loads up to 450 Watts for 60 seconds or less are acceptable, (10% duty cycle max.).

Peak power must not exceed 450 Watts.

4

V4 can be adjusted to 16 V with a minimum load of 5 A on V1.

5

For operation of V4 greater than 24 V, consult factory.

6

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

7

Models without suffix G use the lead solder exemption
