25, 40 & 50 AMP Rated

"COOL ONE" Panel Mount SCR Power Controller with 0-135Ω Input
(Phase Angle)

Anacon Power & Controls SCR Controller's are designed to offer proven solutions to both Phase Angle and Burst Fire applications. Our Phase Angle SCR Controllers operate by varying the firing point of an SSR's input.  The power delivered to the load is proportional to the command input signal. SCR Controllers allow you to apply more precise control to any heater application, regardless of the type of heater elements you choose.

rating number in the standard part number.
Notes:
  • Ratings based upon 100% duty cycle for 20 minutes or 80% duty cycle continuous.
  • Ratings are based upon relays being mounted either individually or side by side with zero spacing.
  • Cool One's unique construction allows better performance than conventional heat sink designs even when mounted side by side.

The APCSCR series are SCR Power Controllers (phase angle). The 0-135Ω input series has a dedicated input and can only accept 0-135Ω. This function is dip switch selected at Anacon and is noted above. The power delivered to the load is proportional to the command signal input.

Input selection is restricted to 0-135Ω.

A line to 24Vac transformer supplies power and phase information to the controller card. The transformer is connected across the AC power source as noted below. There is a feature to compensate for line voltage variation. By adjusting the phase angle automatically with line voltage changes, constant power is maintained at the load. To use the line voltage compensation feature properly, the 24Vac transformer should be fed from the same mains as the load circuit to be controlled per the wiring diagram per Figure 1. Line voltage compensation can be enabled or disabled via dip switch selections noted above.

A separate control transformer is required for each APCSCR assembly.

See User Manual for complete list of commands & wiring options.
