PSW-720L44 | Power supply 2-channel, multi-range, 720W, CH1: 80V CH2: 80V, LAN, USB, analogue, 3U


The programmable 2-channel multi-range DC laboratory power supply PSW-720L44 is particularly characterized by its high efficiency and the flexible setting and application options.

The flexible, adjustable power control of the power supplies of the GW Instek PSW series automatically adjusts the output voltage and output current so that the maximum output power is not exceeded.

Thanks to this high level of flexibility, the power supply units can be used for many performance requirements. This noticeably reduces your costs for additional power supplies.

The GW Instek PSW-720L44 has a constant voltage (Constant Voltage CV) and constant current (Constant Current CC) function. This protects your device under test (DUT) from overshoot or current spikes.

Rise times and fall times (slew rates) can be set for both voltage and current. This makes it possible to test the DUT in a controlled manner with changing voltages and currents.
You can use the output on/off control with an adjustable delay to define fixed times for switching on or off connected power supplies. Simulate and test your DUT with changing voltages or currents. These processes are programmed via the analogue interface on your PC.

Of course, the DC power supply has overvoltage (OVP), overcurrent (OCP) and overheating protection (OHP).

The GW Instek PSW-720L44 is equipped with USB and LAN interfaces as standard. A GPIB-USB adapter is optionally available. The analog interface available on the rear is also available as an option.
