Instek PSW 800-4.32 DC Power Supply 1080W

The GW Instek PSW 800-4.32 is a single-output, multi-range programmable DC power supply engineered for benchtop testing, automated systems, and high-voltage component evaluation. Operating at up to 800 V and 4.32 A with a 1080 W maximum power rating, it provides wide operating flexibility within a compact 1/2-rack form factor.

GW Instek PSW 800-4.32 Power and Operational Performance

The instrument uses an advanced multi-range power envelope to maximize operational versatility within its 1080 W power envelope:

• Multi-Range AutoRange Envelope: The system automatically calculates combinations of voltage and current. It supplies higher voltage at lower current or higher current at lower voltage. Consequently, a single unit covers testing requirements that traditionally require multiple fixed-range power supplies.
• Adjustable Slew Rate: Operators can independently program voltage and current rise and fall times. Therefore, test setups prevent damaging inrush currents during sensitive semiconductor turn-on phases.
• Constant Voltage (CV) and Constant Current (CC) Priority: Dedicated CV and CC priority modes safeguard non-linear loads, such as power converters and LED arrays, from transient current and voltage spikes.
• Bleeder Circuit Discharge Control: An internal bleeder resistor safely discharges output capacitors upon power-down. As a result, safe bench conditions are restored quickly after high-voltage test sequences.

System Integration and Hardware Architecture

Built for both benchtop testing and high-density automated test equipment (ATE) racks, the unit emphasizes rugged physical construction:

• Compact 1/2-Rack Chassis: The space-efficient form factor enables side-by-side mounting in standard 19-inch equipment racks. Thus, testing facilities conserve valuable rack real estate.
• Series and Parallel Scaling: Units can connect in series (up to 2 units) to double output voltage, or in parallel (up to 3 units) to triple current output.
• Automated Test Interfaces: Built-in USB and LAN interfaces support remote programming and data acquisition. Furthermore, the unit supports standard SCPI command protocols and LabVIEW drivers.
• Hardware-Level Protection: Comprehensive OVP (Over Voltage), OCP (Over Current), and OTP (Over Temperature) circuits trip quickly to safeguard the supply and attached devices.

Industrial Applications and Testing Utility

The supply supports diverse high-voltage test applications across automotive electronics, aerospace, and energy storage. Specifically, it accommodates solar inverter testing, electric vehicle subsystem evaluation, DC-DC converter characterization, and high-voltage relay validation.

Ultimately, the GW Instek PSW 800-4.32 programmable DC power supply offers testing engineers a versatile, space-efficient solution for reliable high-voltage power delivery.
