Profile
Wattcor W401 line offers a wide range of solid state power controllers with "zero crossing" switching for resistive loads with 45A and 100A current ratings and 460Vac nominal voltage.
This product is designed to be used as intelligent peripherals in industrial heat-treatment processes using programmable logics or computers.
A switch enables to select the external -On/Off (standard)- or internal control mode, controlled by a microprocessor and configurable via serial link.
The RS485 MODBUS communication system allows the control of variables, such as power capacity control and cycle time, as well as the accurate monitoring of load voltage and current RMS values.
Data strings are also available, concerning: instrument identification, diagnostic and hardware configuration.
The conduction is activated by the control signal at the first zero crossing of the load power voltage.
Switching off occurs by the first zero crossing of the load current after disabling the control signal.
The control of three-phase loads can be made by two or three W401 fired in parallel.
Each model is equipped with a logic (active low) input to disable the power controller and eventually break power supply off.
The auxiliary power supply output (+15Vdc) is available to activate autonomous control and inhibition logic inputs. Wattcor W401 series are designed to operate nominal current and voltage values at 40°C ambient temperature.
The internal extra-fast fuse option is available for both ratings.
Signal connections are made via "plug-in" connectors to enable easy wiring, while power connections are made through terminals integrated in the mounting socket, where the power controller itself is placed.
The instrument mounting is on panel by means of screws.
