DOLD PH 9260.91 AC 48 - 480V AC 50A

The PH 9260 series AC Semiconductor Relay with switching at cero crossing. The semiconductor relay switches at zero crossing and is suitable for many applications extrusion machines for plastic and rubber, packaging machines, solder lines and machines in food industry. The solid state relay PH switching at voltage maximum is suitable to switch transformers. It is designed with 2 anti-parallel connected thyristors switching at zero crossing. When connecting the control voltage the output of the semiconductor relay is activated at the next zero crossing of the sinusoidal voltage. When disconnecting the control voltage the output is switched OFF at the next zero crossing of the load current. The LED shows the state of the control input. The service life and long-time reliability of a solid-state relay depends on its installation and use. Load type, load current, switching frequency, mains voltage and ambient temperature must be taken into account during the project design.
