Description
Switching power supplies are designed for high efficiency and small size. They incorporate a switching regulator to convert electrical power efficiently. Switching DC power supplies regulate the output voltage through a process called pulse width modulation (PWM). Using a PWM allows various topologies to be used such as buck, boost, forward converter, half bridge rectifier, or flyback depending on the output power requirements. The PWM process generates some high frequency noise, but enables the switching power supplies to be built with very high power efficiency and a small form factor. A switching power supply has greater efficiency than linear regulators because the switching transistor dissipates little power when acting as a switch.
Product characteristics:
- ideal for Nema 23 stepper motors
- small volume, light weight
- safety, high reliability
- excellent performance: switching power supply has delay detection circuit of 5-10 seconds to protect the load from high voltage and large current output
- full protection function: short circuit, overcurrent, overload, overheat
- fan dependent cooling
- convenient installation
