Information About DC21-24C0-S000
The DC21-24C0-S000 is a Watlow DIN-A-MITE C Series power controller developed for industrial resistance heating systems. Its construction combines semiconductor switching components, two controlled power legs, an integrated heat sink, and forced-air cooling within an industrial power control assembly. The unit is designed for integration with compatible temperature controllers, PLC outputs, and automation circuits providing a low-voltage DC switching command. Its zero-cross switching technology and shorted-output monitoring support repetitive heater operation while providing fault indication when an SCR output fails in a conducting state.
Key Features:
-
DIN-A-MITE C Series: Industrial solid-state power controller for electric heating applications.
-
Three-Phase Operation: Designed for compatible three-phase AC resistance heating loads.
-
Two Controlled Legs: Switches two phases of the three-phase power circuit.
-
Rated Output Current: Provides a nominal 65 A load current capacity under specified cooling conditions.
-
Operating Voltage: Supports 120–240 VAC line and load voltage.
-
DC Control Input: Accepts a 4–32 VDC switching command.
-
Contactor-Style Operation: Provides on/off heater power switching in response to an external control signal.
-
Zero-Cross Switching: Activates SCR devices near the AC voltage zero crossing to reduce electrical interference.
-
Fan-Cooled Heat Sink: Uses forced-air cooling to dissipate heat generated by the power semiconductors.
-
Shorted SCR Alarm: Provides fault indication when a controlled output remains conducting unexpectedly.
-
Touch-Safe Terminals: Protected power connections help reduce accidental contact during installation and maintenance.
-
Short-Circuit Current Rating: Supports up to 200 kA SCCR when installed with the manufacturer-specified protective devices.
The DC21-24C0-S000 delivers the reliability and precision required for three-phase electric heater switching, SCR fault monitoring, and industrial thermal process control.
