Series H12 25-90Amp * 480 Vac * AC Output * 1200 Volt Blocking High voltage relays use IC driven circuits for switching loads up to 660 VAC. All models come with 1200 Volts blocking and are available with either AC or DC input (coil) control. Types H12CA, H12CD and H12WD are snubberless (reduced leakage current). Manufactured in Crydom's ISO 9002 Certified facility for optimum product performance and reliability. * Panel Mount * Up to 660 Vac * Zero Voltage Switching and Random Turn-On * SCR Output MODEL NUMBERS DC CONTROL H12CD4850 H12CD4890 H12WD4850 H12WD4890 A C C ONTROL H12CA4850 H12CA4890 H12D4825 H12D4850 H12D4875 H12D4890 OUTPUT SPECIFICATIONS 48-660 48-660 48-530 48-530 48-530 48-530 Max.
