WebThe general lighting load for hospitals is 2 volt-amperes per square foot. Therefore, multiply the square-foot area by 2 volt-amperes per square foot (45,000 × 2 = 90,000). The general lighting load is 90,000 volt-amperes. Multiply the first 50,000 by 40 percent (50,000 × 40% = 20,000). This leaves 40,000 volt-amperes (90,000 – 50,000 = 40,000). WebThis technology is called light load mode. Switching between PWM control featuring a constant period at heavy loads (large current) and PFM control that changes the period at light loads (low current) depending on the conditions makes it possible to further improve efficiency.
