4.2.5.1 AC Solid State Relays

The preferred relay to use in most cases is the AC solid state TRIAC relay on the primary-side of the rectifier transformer.
Mobiltex has several standard AC relays and heatsinks available as optional components for the RMU5.
K0513245010 AC Relay - 24-280 VAC RMS 50 Amps max. 0-8A=No Heatsink, 8-50A=HE-54
K0513211010 AC Relay - 24-280 VAC RMS 110 Amps max. 0-8A=No Heatsink, 8-60A=HE-54, 60-110A=HE-90
K0513285010 AC Relay - 48-530 VAC RMS 50 Amps max. 0-8A=No Heatsink, 8-50A=HE-54

Figure 12 Mobiltex Standard Single Phase Solid State AC Relays

All 3 relays are about the same physical size and look very similar. The heatsink requirements are listed above. These
relays can be used to either interrupt the primary line AC (for 120 & 230 volt rectifiers) or the secondary AC of the
rectifier.
K05232R5016 AC Relay - 3 phase, 48-530 VAC RMS 50 Amps max. 0-4A=No Heatsink, 4-30A=HE-90
