Littelfuse PHS Relays Provide Exceptional Phase Control Protection
The PHS Series Relays are designed for changing lamp intensity, varying the speed of a fan, or controlling the temperature of a heater. The effective output voltage is adjusted with an accessory external potentiometer suitable for line voltage applications.
Operation Upon application of input voltage, effective output voltage can be adjusted by changing the external resistance value. As the external resistance increases, the effective output voltage decreases, and the inverse is also true.
- External adjustment – potentiometer rated at 230 V ac
- Up to 20 A steady state – 200 A inrush
- Single hole surface mounting
- Solid-state design
- Allows direct control of heavy loads
- Allows direct control of heavy loads
