The 77 series “single-pole” solid state relays from Finder are now available in eight new versions, including a 30A current rating to complement the existing 5A models. The range includes distinct models for zero-voltage and instantaneous switch on.The existing 5A model range is designed specifically for lighting control where zero-voltage switching can significantly reduce high inrush currents. The instantaneous switch on feature provides near instant switching for high speed operation, and simultaneous switching in multi-phase circuits, such as three phase motors.
The high inrush capability of 520A (10ms) guarantees reliability over a long life in a wide range of applications, particularly the switching of lighting where power factor compensation and electronic ballasts have historically been problematic, also making this ideal for the control of heating, solenoids and motors.
The relays are ideal for use in control panels and cabinets in both industrial and commercial applications due to their 22.5mm housing incorporating the heat sink and designed for 35mm rail mounting.
Features:
- Can switch single phase motors up to 2.5kW or lamp loads up to 6000W
- Silent, high speed switching
- Suitable for many environments
- Input voltages of 230Vac and 24Vdc
