Open switch power supply in stock, free delivery
2025.09.17
Open switching power supplies are available in stock and free of charge. The working process of an open switching power supply is quite easy to understand. In a linear power supply, the power transistor operates in linear mode. Unlike a linear power supply, a PWM switching power supply operates the power transistor in on and off states. In these two states, the volt ampere product added to the power transistor/power device is the loss generated on the power semiconductor device.
Features:
1. Small size and light weight: Due to the absence of power frequency transformers, the volume and weight are only 20-30% of linear power supplies.
2. Low power consumption and high efficiency: Power transistors work in a switching state, so the power consumption on the transistor is low and the conversion efficiency is high, generally 60-70%, while linear power supplies only have 30-40%.
