Datos técnicos

Panorámica

Wattcor W212 line offers a wide range of solid state power controllers with "zero crossing" switching for resistive loads with current ratings up to 600A and 660Vac nominal voltages.
The models of the W212 series accept logic commands in volts, milliamperes and from a potentiometer.
Directly on the W212 it is possible to set, using a trimmer, the cycle time which is used for the power modulation in relation to the input analogue signal.
The control of the triphase loads can be made with a W212 used as master and one or more W211 used as slaves.
Each model is equipped with a logic input to disable the solid state relay/power controller and eventually break off power supply.
Different options are available for the more critical applications, such as the "load control" (RPC option) which detects and indicates partial load failure interruption/cut-off, with a LED on the faceplate, and a relay alarm output. The DTC option allows the control of a possible SCR short-circuit or the complete current failure in the load.
A further safety option is represented by the "electronic cut-off" circuit, (DE option), a device protecting the power element against a momentary excess current higher than a selected value, corresponding to approx. 13 times the nominal current of the solid state power controller.
The alarm condition disables the power supply, activates an alarm relay (in common with RPC option) and allows the instrument resetting through a front button.
The WATTCOR W212 series are designed to guarantee nominal current and voltage values at 50°C ambient temperature, with a working temperature range from -5°C up to 60°C.
250A and 600A units are supplied with internal fuse and digital output for the fuse status. Signal connections are made via "plug-in" connectors to enable easy wiring.
The instrument can be DIN rail or panel mounted (from 250 up to 600A current ratings, panel mounting only).
