The 1024A is available as a Custom OEM model only. Contact the factory for more information.
The models 1024 and 1024A are single phase, zero- cross power controllers.
The model 1024 controller responds to a DC command signal between 3.5 and 32 Volts.
The model 1024A controller responds to an AC com- mand signal between 90 and 280 Volts.
Both models control the average AC voltage to the load proportional to the command signal.
The command signal is electrically isolated from the line and load voltage.
