PSL Series Single-Channel Regulated Linear DC Power Supply with 4 Digits Display Linear power supplies are designed for low noise and quiet since there is no highfrequency switching. They are commonly used where excellent regulation, low ripple, low electromagnetic emissions and good transient response are needed. A linear power supply typically uses a transformer to step down AC voltage and then uses a series of rectifier circuitry and filtering process to produce a clean DC voltage. The PSL Series is a high-performance, precision DC regulated power supply with a digital LED display. Our PSL series has constant voltage mode, constant current mode, and current output protection function for most demanding electronic applications. Some examples of applications that may require communication equipment, power equipment, medical equipment, laboratory test equipment, control circuits, computer and industrial applications, etc. The PSL series provides full load stable performance, an intelligent ventilation fan to suppress / minimise acoustic noise during operation, and adjustable, fully flexible voltage and current readings. On-screen, three sets of the display. Operators directly monitor output voltage, current and wattage usage status simultaneously. All these excellent performances with extract stability and enhanced linearity make the unit outstanding. The PSL series is the ideal equipment where high performance and precision regulated DC power source is required.
