GW Instek PSW 800-1.44 DC Power Supply

The GW Instek PSW 800-1.44 is a single-output, multi-range programmable DC power supply. It is engineered for benchtop electronics testing, semiconductor evaluation, and automated manufacturing lines. Operating at up to 800 V and 1.44 A with a 360 W maximum power rating, it delivers versatile power output profiles within a compact 1/6-rack chassis.

GW Instek PSW 800-1.44 Power and Output Capabilities

The instrument utilizes multi-range capability to deliver wide voltage and current envelopes within its 360 W capacity limit:

• Multi-Range Power Envelope: The system automatically adjusts output combinations. It allows higher voltages at lower currents or higher currents at lower voltages. Consequently, one unit covers testing needs that typically require multiple fixed-range power supplies.
• Adjustable Slew Rate: Operators can independently program voltage and current rise and fall times. Therefore, technicians can prevent damaging inrush currents when powering delicate semiconductor components.
• Bleeder Circuit Control: An integrated bleeder resistor circuit accelerates output capacitor discharge when powering down. As a result, safe bench conditions are restored quickly after high-voltage test cycles.
• Constant Voltage (CV) and Constant Current (CC) Priority: CV and CC priority modes protect non-linear loads, such as LEDs and DC-DC converters, from transient overshoot during turn-on.

Hardware Architecture and System Integration

Designed for high-density automated test equipment (ATE) racks and clean workbenches, the unit emphasizes rugged physical design and fast connectivity:

• Compact 1/6-Rack Form Factor: Its slim vertical profile enables multi-unit side-by-side mounting in standard 19-inch racks. Thus, facilities maximize benchtop and rack space efficiency.
• Series and Parallel Expandability: Up to two units can connect in series to double output voltage. Meanwhile, up to three units can link in parallel to triple output current.
• Standard Automated Interfaces: Standard USB and LAN interfaces provide straightforward remote programming and automated data collection. Furthermore, it supports standard SCPI command protocols and LabVIEW drivers.
• Comprehensive Protection Mechanisms: Hardware-level OVP (Over Voltage), OCP (Over Current), and OTP (Over Temperature) safeguards trip rapidly to protect both the load and supply.

Applications and Industrial Utility

The supply serves diverse high-voltage, low-current testing applications across aerospace, renewable energy, and industrial electronics. Specifically, it supports solar inverter component testing, high-voltage relay verification, capacitor breakdown analysis, and electric vehicle subsystem qualification.

Ultimately, the GW Instek PSW 800-1.44 programmable DC power supply offers testing engineers and QA laboratories a flexible, space-saving solution for precision high-voltage power delivery.
