Phoenix Contact DIN Rail Power Supply, Adjustable Output Voltage, IP20 Rating - STEP-PS/ 1AC/24DC/4.2 - 2868664
An internal varistor converts and steps down your chosen input voltage to a stable load of 24V DC that's handy for running battery-powered equipment. Thanks to an adjustable output, you can further tweak this between 22.5 and 29.5V DC to suit the specifics of your application. This PSU reliably functions in operating temperatures between -25°C and +70°C to cope with demanding settings.
Features & Benefits
• IP20 rating means it's touch-safe
• Internal slow-blowing 4A fuse on inputs cuts off faults to prevent damage
• Transient surge protection protects you and your kit against spikes and lightning strikes
• Adaptable 24 to 12AWG (0.2 to 2.5mm²) screw connections achieve a robust electrical link
