SMART 50 A SCR Power Controller in Evaporation Boat Heating Control at Shanghai Baodu Vacuum Coating

Industry: Vacuum coating  |  Reference site: Shanghai Baodu  |  Configuration: SMART SCR power controller 50 A

Kulun Electric’s SMART series 50 A SCR power controller is applied at the Shanghai Baodu vacuum coating site, for evaporation boat heating control in vacuum hydrogen sulfide film deposition. The project uses multiple SCR power controllers for per-loop control of evaporation boat heating circuits, providing stable, adjustable and integration-friendly heating power output for the coating process.

1. Project Overview

2. Application Background

The evaporation boat heating stage of vacuum coating equipment has high requirements for power output stability and multi-loop control consistency. Heating circuits must be regulated according to process status to keep evaporation stable and reduce the effect of temperature fluctuation on coating quality and production continuity.

The Shanghai Baodu site uses multi-loop evaporation boat heating control, requiring stable power regulation, fast response, centralized arrangement and easy system integration. Kulun configured the SMART 50 A SCR power controller for these conditions, meeting per-loop control of vacuum coating heating circuits.

3. Requirements & Technical Challenges

For this application, the heating and power control system had to address the following points:

• Multi-loop heating control: Multiple evaporation boat groups need per-loop regulation with controllable output on each circuit.
• High output stability requirement: The coating process is sensitive to heating fluctuation and needs smooth output.
• Limited integration space: Coating equipment electrical systems have many loops in compact space, so the product must be easy to install and arrange.
• Continuous operation reliability: The heating system must run for long periods, reducing downtime impact on production rhythm.
• Protection and maintenance: Overcurrent and overheating protection are needed, with easy observation, commissioning and maintenance.
