Solid State Relays
Industrial, 1Phase Peak Switching
Type RM1C
• Ideal for switching of transformers
and other highly inductive loads
• Direct copper bonding (DCB) technology
• Thyristor power units
• LED indication
• Clip-on IP20 protection cover
• Housing free of moulding mass
• Self lifting terminals
• Operational ratings up to 100AACrms and 600VACrms
• Blocking voltage up to 1400Vp
• Opto isolation: 4000 VACrms
Product De scrip tion
The peak switching SSR is
primarily used for transformer applications. By applying
DC control voltage, the output
semiconductor is activated at
the peak of the line voltage.
The semiconductor switches
OFF, when load current crosses zero, upon removal of the
control voltage. The LED indicates when the output is activated.

va-rying stray inductances
and stray capacitances, it is
al ways advisable to use external overvoltage pro tec tion.
