You may refer to chapter 11 on “How to easily perform voltage testing on SMPS circuit”. I have built many circuits in my life, but this is actually the first time I’ve built a power supply circuit from scratch. For instantaneous attracted armature type relays, the minimum closing and resetting values are checked. Check behind the CRT/Screen- usually 5,12 or 24 VDC External power connection Door Interlock circuit. Investigate values which deviate from those of similar bolted connections by more than 50 percent of the lowest value. Using the previously measured rectified DC voltage, and Zener voltage, calculate the minimum value of R s required to protected the Zener diode under the condition when the load is an open circuit (this is the worst case condition). If the measurement is not within this range, the system never sees the Power_Good signal and therefore does not start or run properly. “Emergency Generator Mode Selector Switch” is in the “NORMAL” position. Among these provisions were a definition of EPS and a requirement that DOE prescribe “definitions and test procedures for the power use of battery chargers and external power supplies. ) Make sure the new RAM module is seated properly. The number under 2716 is the quantity of 2716 EPROM's (or 9316 proms) that should be used on the board. The primary function of SMPS is to convert the alternating current (AC) power available in homes into direct current (DC) required for a computer system. Set your test meter to it's highest AC voltage scale (at least 750 VAC, preferably 1000VAC). It is very important to keep a multimeter, a small battery-operated device with electrically conductive probes, on hand to test well used power cords, including extension and removable cords.
