Can switching power supplies be paralleled for high current output? When ordered with the "P" option, low profile switching power supplies can be paralleled for high output current. Four units can be connected in parallel for 2880 watts. The power supplies will actually share the current.
The switching power supply is smaller, lighter and more efficient than the linear power supply. For example, a linear power supply would require 600 in 3 of installation space and weigh 26 pounds, while a similar AC-DC switching power supply would require 60 in 3 of installation space and weigh 2 pounds. Linear power supplies have efficiencies in the 40-60 percent range, while switching power supplies have efficiencies in the 70-90 percent range. This means less power is wasted as heat, which reduces operating costs.
Switching power supplies use complex high-frequency switching (using pulse width modulation and feedback) to regulate the output voltage. Switching power supplies also incorporate filtering and shielding to attenuate common-mode and differential-mode noise conducted to the line and load. Current is standard on our switchers, providing the user with input to output and output to versatility. Switching regulated power supplies are highly efficient, small and lightweight, and are available in AC-DC single and wide regulated outputs as well as DC-DC configurations. Our low-profile regulated output switching power supplies can be voltage or current regulated and can be programmed externally.
