Product Model

ABB PSTP-280/16 Thyristor

Product Overview

The ABB PSTP-280/16 is a high-power industrial thyristor widely used in AC power control and rectification circuits. It allows precise current control via gate triggering, enabling accurate load power regulation. This thyristor model features high voltage resistance, high current carrying capability, and fast response, making it suitable for industrial heating, motor control, power electronics, and rectifier systems.

Technical Specifications

• Model: PSTP-280/16

• Type: Thyristor

• Maximum Average Current (IT(AV)): 280 A

• Maximum Repetitive Peak Current (IT(RMS)): approx. 400 A

• Maximum Repetitive Peak Reverse Voltage (VDRM/VRRM): 1600 V

• Triggering Method: Gate triggering

• Package Type: Power thyristor module

• Operating Temperature Range: –40°C … +125°C (junction)

• Cooling: Forced cooling required (heatsink recommended)

• Application Type: Industrial power control, rectification, voltage regulation

• Protection: Can be combined with gate circuit and thermal management for overcurrent/overtemperature protection

Advantages & Key Features

1. High current capability: Rated average current up to 280 A for high-power loads.

2. High voltage tolerance: Max repetitive peak voltage of 1600 V suitable for industrial high-voltage environments.

3. Fast response: Gate-triggered control allows precise power regulation.

4. Modular packaging: Easy to install in industrial control cabinets with heatsinks.

5. High reliability: Industrial-grade design tolerates high temperature, vibration, and electrical interference.

6. Flexible applications: Suitable for motor drives, industrial heating, rectifiers, and AC power control.

Application Areas

• Industrial heating systems (resistance furnaces, electric heaters)

• Motor soft-start and speed control systems

• Rectifiers and power conversion systems

• Thyristor regulators and AC power control applications

• Automated industrial production lines and large power electronics equipment

Precautions

1. Ensure current, voltage, and cooling requirements meet system design before installation.

2. Use appropriate heatsinks and temperature monitoring to prevent overheating.

3. Avoid exceeding maximum rated current, peak voltage, and ambient temperature.

4. Ensure proper insulation and grounding during installation to prevent shock or device damage.

5. Design gate control circuitry carefully to avoid misfiring or overcurrent.

6. Periodically check cooling systems and electrical connections to ensure safe long-term operation.
