GW Instek PSW-720H88 DC Power Supply

Overview

The GW Instek PSW-720H88 is a dual-channel programmable switching DC power supply from the PSW-Multi Series. It delivers 800/800V output with a maximum power of 720W. This supply is engineered for high-voltage applications requiring precise voltage and current control, particularly when testing power-sensitive components such as LEDs and battery systems. The CV/CC priority mode selection allows users to prevent inrush current damage during power-on transients.

Key Features

• Dual-channel configuration with 800V/800V output and 720W maximum power
• Output latency between channels less than 0.1ms for synchronized operation
• CV/CC priority mode selection to minimize inrush current and protect sensitive devices
• Adjustable slew rate for controlled voltage and current rise and fall times
• Over-voltage (OVP) and over-current (OCP) protection at 110% of rated values
• Advanced web server interface with direct SCPI command execution
• Standard LAN and USB connectivity with optional GPIB-USB and RS232-USB interfaces
• Data logging at 1-second intervals with sequence editing capability
• LabVIEW driver support for automated test sequences
• Bleed circuit for accelerated voltage fall times

Applications

• High-voltage LED characterization and burn-in testing
• High-voltage battery testing and capacity verification
• Power consumption analysis of high-voltage electronic devices
• I-V curve characterization for high-voltage semiconductor components
• Automated high-voltage manufacturing test sequences with USB storage
