Product Description P/N: DC20-60F0-S000
Description
The Watlow DC20-60F0-S000 is a DIN-A-MITE C SCR power controller that regulates three-phase electric heating loads through two controlled legs. It converts a 4–20 mA DC command signal into proportional heater power using zero-cross, variable time-base switching.

Information About DC20-60F0-S000
The DC20-60F0-S000 is part of Watlow’s DIN-A-MITE Style C family, combining solid-state switching components and a naturally cooled heatsink in one assembly. Its four-SCR arrangement controls two legs of a three-phase circuit supplied at 277–600 VAC, 50/60 Hz. The proportional input interfaces with a compatible temperature or process controller supplying a 4–20 mA DC signal. This configuration includes a shorted SCR alarm, standard customization options, and English user documentation.
Key Features:
- Three-Phase Power Control: Regulates a three-phase heating circuit through two controlled legs using four SCRs.
- Proportional Current Input: Accepts a 4–20 mA DC command signal from a compatible external controller.
- Variable Time-Base Operation: Adjusts the switching pattern to vary average power delivered to the heater.
- Zero-Cross Switching: Switches at AC zero crossings to reduce switching-related electrical noise.
- Natural Convection Cooling: Dissipates heat through an integrated heatsink without a cooling fan.
- Shorted SCR Alarm: Signals detected load current when the control command requests the output to remain off.
- Industrial Voltage Range: Supports nominal line and load voltages of 277–600 VAC at 50/60 Hz.
- Flexible Mounting: Supports DIN-rail or back-panel installation.
The DC20-60F0-S000 delivers the reliability and precision required for proportional electric heater power control in industrial thermal systems.
