  • Page 12: Power Dissipation

    For example, if a 1260-21 module (containing 12 relays) has 3 relays closed, passing a current of 10 A, then: Total power dissipation = [(current) * (path resistance) * 3 ] + (coil power * 3) + (quiescent power) Racal Instruments © 2005 Specifications 1-4...
  • Page 13: About Mtbf

    Additionally, if fewer plug-in modules are used, more power may be dissipated by the remaining cards. By using a chassis with high cooling capacity, such as the Racal Instruments 1261B, almost any configuration may be realized. The 1260-21 MTBF is 1,500,000 hours, calculated in accordance...
