GW Instek PFR-100L power supply
Details
The GW Instek PFR-100L is an industrial high-quality power supply rated for 100W, with maximal output of 50V/10A (not simultaneously). The power supply has a fanless design, making it very silent and therefore suitable for industrial purposes. The PFR-100L can operate in two ranges: 50V/2A or 10V/10A, and has a resolution of 2mV/1mA. Connections to the power supply can either be made with the front terminals for easy test lead replacement, or with the rear terminals, which is more suitable for rack mount assembly operation.
The PFR-100L has several interface possibilities, such as USB, RS232/ RS-485, and analog control, to obtain full remote control over the power supply. Additional features such as an output on/ off delay function, an adjustable slew rate, a remote sensing function, and the possibility for web server monitoring and control enhance the capabilities of the GW Instek PFR-100L, making it especially suitable for industrial applications.
