Solid State Relays Industrial, 1-Phase ZS (IO) w. LED and Built-in Varistor Type HPR48 • Zero switching • Direct copper bonding (DCB) technology • LED indication • Built-in varistor 480 V • Clip-on IP 20 protection cover • Self-lifting terminals • Housing free of moulding mass • 2 input ranges: 4-32 VDC and 20-280 VAC/22-48 VDC • Operational ratings: Up to 75 AMPS rms • Rated voltage: 480 VAC rms • Blocking voltage: 1200Vp • Opto-isolation: > 4000VAC rms Ordering Key Solid State Relay Rated voltage Control voltage Rated operational current Product Description The industrial, 1-phase relay with antiparallel thyristor output is the most widely used industrial SSR due to its multiple application possibilities. The relay can be used for resistive, inductive and capacitive loads. The zero switching relay switches ON when the sinusoidal curve crosses zero and switches OFF when the current crosses zero. The instant-on relay HPR 48 A 25 with DC control input can be used for phase control. The built-in varistor secures transient protection for the heavy industrial applications, and the LED indicates the status of the control input. The clipon cover is securing touch protection to IP 20. Protected output terminals can handle cables up to 16mm2.
