The Schneider Electric / Modicon 140CPS11420 is a power supply module in the Quantum automation platform. It can use a summable or standalone power supply type. The module has an internal output overvoltage and overload protection. It comes in a standard module format and weights 0.65 kg. When in a standalone configuration, the 140CPS11420 uses a maximum current of 11 amps. In a summable configuration, the module has a maximum current of 20 amps. Its internal power dissipation is less than 12 watts at a full load.

A normally closed relay contact rated at 220 volts AC, 6 amp / 30 volts DC, 5A is available on terminals 1 and 2 of the power terminal strip. This contact set may be used to signal input power Off. The relay will de-energize when input power drops below 70 volts AC, when the input voltage is set to 115 volts AC, or 140 volts AC when the input is set to 230 volts AC. Its output to the Bus is 5.1 volts DC. No minimum current is required. The module's input frequency can range from 47 - 63 Hz. the 140CPS11420's input voltage total harmonic distortion is less than 10% of the fundamental root mean square value. The input power interruption is no less than 1 second when in a 1/2 cycle at full load, and at the minimum rated line voltage and frequency.

Remove the power line prior to insertion or removal of the module.Use only compatible combinations of summable and standalone power supplies in the Quantum back plane as stated above. If these precautions are not taken, serious injury and/or equipment damage could occur.
