It’s part of the UNI 901 PHT series. “PHT” stands for Phase Angle High Power Thyristor / SSR – analog phase‐angle controlled SSR.
-
“44” is likely the input voltage code (control / input specification), often meaning 4‑20 mA input with 100 Ω impedance for that input type.
-
“50” is the load current rating: 50 Amps.
-
“420” I believe refers to the output voltage / isolation rating (or part of the series where the SSR can handle up to 420 VAC or is designed around that in some way).
-
“AL5” seems to be the body/insulation or design code (material, mounting, heat‐sink version) used by Unison.
Additional Information:
- Item Code: PHT
- Production Capacity: MAX
