The Series ZD, Series ZD20CF, Series ZD24CC, and Series LPD70 solid-state relays provide short-circuit and overload protection. The 1-A, 80-Vdc ZD uses a power FET switch and optical isolation to ...
Overcurrent relays with inverse definite minimum time (IDMT) characteristics are widely used in power systems to protect ...
In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...
