Information About DB20-60K2-0000
The DB20-60K2-0000 is a Style B controller designed for integration into electric heating control panels. Its four SCRs form two switched legs, with an integrated heat sink that dissipates heat through natural convection. The K2 input configuration interfaces with compatible AC control outputs and provides zero-cross contactor operation for resistive heater loads. This configuration supports DIN-rail or back-panel mounting and specifies no alarm option and an English user manual.
Key Features:
- Three-Phase Switching: Controls two legs of a three-phase power circuit using four SCRs.
- Load Voltage Compatibility: Supports nominal line and load voltages of 277–600 VAC.
- AC Control Input: Accepts a 100–120 VAC command for contactor-style switching.
- Zero-Cross Operation: Starts conduction near the AC voltage zero crossing.
- Natural-Convection Cooling: Dissipates switching heat through an integrated heat sink without a cooling fan.
- Solid-State Output: Switches heater current electronically without moving power contacts.
- Cabinet Installation: Supports standard DIN-rail or back-panel mounting.
- Alarm Configuration: Specified without the optional alarm function.
The DB20-60K2-0000 delivers the reliability and precision required for externally commanded switching of compatible three-phase industrial heater loads.
