ILLUSTRATION 4 – OUTPUT CONTACT DERATING CURVE
6.0 POWER CONSIDERATIONS
The ED2.0 power supply recharge unit adapts any voltage within the specified range of the
board to maintain 80 V across the capacitors. The following voltage thresholds must be
reached to complete the specified operations:
1. The capacitor voltage threshold for an Open operation is 49 volts.
2. The capacitor voltage threshold for a Close-Open operation is 72.5 volts.
3. The capacitor voltage threshold for a Open-Close-Open operation is 78 volts.
Illustrations 5 and 6 are provided to indicate the states of the Ready LED, Ready and Not
Ready output contacts.
