Notes:

1. For U-frame models, the maximum output power is 400W with a minimum of 27 CFM forced air, 220 W maximum with convection cooling.

2. For CNF models, the maximum output is 220 W with convection cooling.

3. For U-frame models, the total combined output power is 320W with a minimum of 27 CFM forced air, 180 W maximum with convection cooling.

4. For CNF models, the maximum output is 180 W with convection cooling.

5. For U-frame models, the total combined output power is 400W with a minimum of 27 CFM forced air, 200 W maximum with convection cooling.

6. For CNF models, the maximum output is 200 W with convection cooling.

7. Output can be custom set within range.

8. Measured at 10 kHz ~ 20 MHz bandwidth, with a 22 µF electrolytic and 0.1 µF ceramic capacitor on the output.

9. 1% minimum load is required to maintain ripple and regulation (10% for dual output models).

10. * Discontinued model.
