PK ENG Co., Ltd.

Incheon developer and maker of solid state relays, SCR power regulators and temperature controllers

LISTEDMANUFACTURER Incheon, South Korea

About

PK ENG develops, manufactures and sells power electronics for industrial automation from its base in Bupyeong, Incheon. The core range is solid state relays (SSR) and thyristor (SCR) power regulators for heater control, together with temperature controllers for freeze-protection systems.

Its products are built for compact panel installation, with slim housings, current monitoring, heater-break and overcurrent (EOCR-type) functions, and communication-based status monitoring on newer models. Typical users are plastics, heat-treatment, food and semiconductor/display equipment builders.

Products

Solid State Relays (SSR)

Contactless relays for switching resistive heater loads, including multi-function versions with built-in current detection, heater-break and overcurrent protection.

Key features

  • Single-phase, three-phase and 3-channel single-phase versions
  • Built-in current detection and heater-break alarm (multi-function types)
  • EOCR-type overcurrent protection on SSR-2MF/3MF/M3C
  • Super slim 15 mm and slim 22 mm housings
  • Two-element, two-wire cut-off designs

Applications

  • Injection molding and extrusion heaters
  • Heat-treatment furnaces
  • Food processing ovens
  • Semiconductor and display equipment
  • Single- and three-phase; 15–160 A; 15 mm and 22 mm slim types
