Notes:
1. Peak power of 600 W within 500 µs only applies to single output models
2. Total continuous output power will not exceed 300 W with 25 CFM forced air, 150 W without fan.
3. Total combined continuous output power will not exceed 240 W with 25 CFM forced air, 120 W without fan.
4. Measured at 10 kHz ~ 20 MHz, with 0.1 µF ceramic and 22 µF electrolytic parallel capacitors
5. 1% minimum load is required to maintain the ripple and regulation (10% for dual output models)
