The MCROEM module derives power directly from the host. After supply power is applied to 
the MCR it will be operational in less than 1.2 seconds. 

Supply voltage 

12Vdc +10%/-5%, with ripple of less than 50mV peak-peak.  

Supply current 

Maximum 300 mA, typical 150 mA 

Input power 
requirements 

Maximum 3.60 Watts 

The standards supported by the RF controller are ISO/IEC 14443 Type A, ISO/IEC 14443 
Type B and Mifare Standard. 

The MCR transmitter complies with the following specifications:
